To counter Reliance Jio 4G internet packs, Bharti Airtel has come up with a new prepaid plan. Under the new plan, Airtel is offering 1.4GB data per day and unlimited voice calling in Rs 419. The new Airtel prepaid plan is an open market plan which means it is available across the country and can be recharged from company’s offline as well as online store along with the other vendors.

Airtel’s Rs 419 plan comes with a validity of 75 days and also offers 100 free text messages to customers every day.

The news Rs 419 plan will compete with Jio’s Rs 398 and BSNL’s Rs 349 plan. The Jio plan offers 2GB data per day along with unlimited voice calling benefits, 100 SMS per day and complimentary subscription to Jio Apps for 70 days.

Meanwhile, a report by Bernstein claimed thatReliance Jio, the new telecom player, may capture the top position by 2021 on a revenue basis.

“Given the current rate of ongoing customer acquisition, Jio could reach the leading position on a revenue basis by 2021 and on a subscriber basis by 2022,” Bernstein analysts Chris Lane and Samuel Chen said in the report on Monday.

No start-up operator has managed such a feat anywhere and certainly not in a market where penetration levels among the ‘middle classes’ were already high, it said, adding Bharti Airtel had survived extreme Darwinian competition to emerge as a competitive market leader, while Vodafone has the backing of a global giant.

Bernstein expects Jio to reach 28% revenue market share and 26% subscriber share by the end of this financial year (March 2019) as it did not see both Bharti and Vodafone responding directly. “Neither Bharti nor Vodafone Idea have the stomach to engage in a pointless subsidy war. Instead we believe they have accepted their fate, and are looking forward to a time when Jio, having achieved a leading position, starts to monetise their base through higher pricing,” the report said.

Read Time: 3 minutes

Out of all the features rolled out with WhatsApp beta, one of the most awaited and cherished one is the “dark mode” (or night mode). Apart from carrying along with it an aesthetically-pleasing dark design factor, dark mode can also add to the overall user experience by improving readability, reducing eye-fatigue, and enhancing the overall battery consumption on the device among others.

However, no word is out yet on the official launch of dark mode and it’s still under works. But, till then you can play around with the feature on your device. Here’s how.

WhatsApp Dark Mode for Android

The first step to be able to enable dark mode for WhatsApp on your device is to run the latest Android Q beta version. Once you have the OS running on your device, follow these steps:

  • Turn on the Android Q’s native dark theme on the device by going to Settings, select Display, select theme, and then choose ‘dark’.
  • Once you have enabled the dark theme, you then have to turn on ‘developer options’. To enable developer options, go to Settings, select about phone, and then tap the “build number” seven times.
  • Now that you’ve enabled the developer option, you need to select “override force-dark” to apply the theme across all the apps on the phone.
  • Since you have applied dark mode across all the apps, you’ll notice that WhatsApp too would have a dark theme across it. To apply dark mode to chat threads, hit settings – wallpaper – no wallpaper to darken up the thread section. You have now dark mode enabled on WhatsApp.

So, that was super simple on Android. Now, let’s quickly look at how you can enable dark mode on WhatsApp for iOS.

WhatsApp Dark Mode for iOS

We’ll now look at the ‘smart-invert’ method that basically uses the iOS 11’s “smart invert’ feature that reverses the display color in an iPhone. can give your WhatsApp a darker appearance on iOS.

Once you have iOS 11 on your phone, go to settings, select General, then Accessibility, select display accommodations – Invert colors – smart invert. You’ll have a darker- looking appearance across your device, without it interfering with the quality of your photos or video.

However, the theme doesn’t apply across all parts of WhatsApp. For instance, if you want a dark theme across chat threads, you’ll have to pick a darker chat background wallpaper. Also, in case you don’t want any discrepancies at all, in terms of media quality, you can disable the feature for other apps excluding WhatsApp.

After making a major uproar in the market with the launch of its new smartphone series, OnePlus might soon announce the OnePlus TV soon in India,

Serial tipster Ishan Agarwal mentioned on Twitter, “Have some good news for you all: The OnePlus TV is not very far away, at least according to one source. The launch might be soon, so stay tuned. I have very high expectations from it, what about you.”.

Given that OnePlus is known to offer affordable yet premium-feel smartphones, its television sets are also expected to be the same: Premium, yet affordable by all.

OnePlus hasn’t revealed any details regarding the TV or its launch. However, it is believed that the TVs display might not be OLED, as it is available in other premium TV sets. Other smart features that the TV reportedly might sport includes a 4K HDR display, an AI voice assistant, ability to integrate with other devices, and will run on OxygenOS.

The news of OnePlus branching out and working on its TVs first came to light, last year. Pete Lau mentioned an interview that OnePlus might launch TVs in 2020 and India would be the first nation to get the OnePlus TV.

This is because OnePlus wants to take its time creating a software that can truly offer an immersive and unique experience to the users.

Now, although the TV isn’t out yet, we can’t wait to see how OnePlus would bring a premium touch to affordable TVs and how it would fair against major rivals in a saturated Indian smart TV market.

Google is about to introduce a System-Wide Dark Theme with the arrival of Android Q. However, many apps from the company still lack proper Dark Mode. Gmail is one of these apps, but according to a new report, this is about to change. Google’s App, Drive and Keep already received their Darker treatment, now the search giant is working hard to deliver a proper experience on their popular e-mail app.

According to a report from AndroidPolice, the long overdue dark mode is starting to show up in Gmail App. However, it still needs to be fully implemented. While developers could found it after digging into the code, the app still lacks a toggle to enable and disable the Dark interface. Furthermore, the dark mode seems to be available in settings only for the time being. It currently, pops up randomly whenever it wants.

Gmail is one of the most popular Google Apps for Android device. So it’s a bit curious to see many other G-apps getting Dark UI treatment and Gmail left in the light-blinding the only option. We believe that Google is saving the best for last. Apparently, the dark mode appears in Gmail v2019.06.09. For instance, if you have this specific version installed in your device, you might sporadically enjoy the new implementation.

Google’s Safe Browsing feature will only work if it knows what websites to protect you against, which is why the tech giant is encouraging users to report suspicious sites. The company has launched a new Chrome extension called Suspicious Site Reporter, which provides you a quick way to let Google know if a website looks, well, suspicious. It adds a flag right next to your other extensions that turns orange if it finds anything doubtful about the page you’re visiting.

Sometimes the things it considers questionable are as trivial as the website not belonging in the top 5,000. But if it does find something truly unsavory, you can easily notify Google by clicking the Send Report button, which will send the company that website’s URL, a screenshot of it and all the site’s HTML. In the announcement, Google said the extension is for “power users”,presumably, that means system administrators — but we were able to access it and send a report just fine.

In addition, Google is revealing a new feature for Chrome 75 that can prevent you from loading deceptive websites. If you try to load go0gle.com instead of google.com, for instance, the browser will issue a full page warning. It will ask if the legit website is the one you actually want to go to, because you don’t usually visit the one you’re loading.

The Vivo Z1 Pro is hpoefully debut soon in India as an international version of the Vivo Z5x smartphone that was recently launched in China. In comparison with the Vivo Z5x, the Z1 Pro will be arriving with some improvements in departments like processor and front-facing camera. Vivo has not confirmed the launch date of the Vivo Z1 Pro in India till now. Couple of live shots of the smartphone have been shared by Indian tipster Mukul Sharma today to reveal its entire design.

The Vivo Z1 Pro images show that the rear shell of the phone is fitted with a vertical triple camera setup at its top-left corner. A fingerprint scanner is available on its rear. The back panel of the phone seems to be made out of glass.

The Vivo Z1 Pro will be one of the first mid-range category smartphones to arrive with punch-hole display design. On June 20, Motorola will be launching the Motorola One Vision smartphone in India with the same display design. Coming back to the Z1 Pro, except for its thicker chin, the display is surrounded by slimmer bezels on all three sides.

Vivo India has confirmed many features of the Vivo Z1 Pro smartphone through its official page. It will be arriving as India first phone fueled by the Snapdragon 712 chipset. The Vivo Z5x features the Snapdragon 710. In comparison, the SD712 offers faster clocking speed than the SD710 chip.

The Vivo Z1 Pro will feature a front-facing camera of 32-megapixel. This feature is being dubbed as in-display camera technology.

The Z1 pro will be backed 5,000mAh battery and it will carry support for 18W fast charging. However, it is yet to be confirmed whether it will be featuring a microUSB or USB-C port. The bottom edge of the phone features a 3.5mm audio jack, microphones and an external speaker apart from the charging port.

There is no information available on the pricing of the Vivo Z1 Pro smartphone till now. Probably, the company may announce it by the end of this month.

Huawei files for trademark registration of its own mobile OS after US ban

Read Time: 2 minutes

Chinese communications giant Huawei now wants to register and launch its one operating system “Hongmeng” that can replace the Android OS on their smartphones and other devices. This follows the ban imposed by the US government on Huawei that prevents the Chinese company from dealing with American companies. The ban means that millions of Huawei phones around the world cannot receive the Android OS updates and it will directly impact the company’s business. Huawei is the second largest smartphone manufacturer in the world and that position too could be in jeopardy.

The information regarding Huawei filing for trademark registration of its “Hongmeng” OS in many non-US geographies has come from a UN body. The countries being mentioned are Cambodia, Canada, South Korea and New Zealand, besides Peru and the European Union.

The US administration, however, does not appear to be in any mood to relax their ban and some senior state department officials have been quoted as saying that the Chinese company won’t be able to carry on without the support of the US companies. US may try and influence some of the friendly nations, including the European Union not to deal with Huawei.

The accusation against the Chinese company may have some connections to the Chinese government and that its software may be used for spying. The company has been denying that it has anything to do with spying for the Chinese government.

It is not as if Huawei has been very successful in obtaining the trademark registration for the “Hongmeng” OS. In the case of Peru, for example, Indecopi, the country’s antitrust agency has disclosed that it had asked for additional information on the OS from Huawei and no response has come forth for nine months.

It may well be some time before the “Hongmeng” OS gets the clearances required and their phones can be updated with the proprietary OS.

Titbits of Tropical Cyclone

Published

on


Spread the love
Read Time: 16 minutes

A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane typhoon tropical storm, cyclonic storm, tropical depression, and simply cyclone. A hurricane is a tropical cyclone that occurs in the Atlantic Ocean and the northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean; in the south Pacific or the Indian Ocean, comparable storms are referred to simply as “tropical cyclones” or “severe cyclonic storms”.

“Tropical” refers to the geographical origin of these systems, which form almost exclusively over tropical seas. “Cyclone” refers to their winds moving in a circle, whirling around their central clear eye, with their winds blowing counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The opposite direction of circulation is due to the Coriolis effect. Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water from the ocean surface, which ultimately recondenses into clouds and rain when moist air rises and cools to saturation.

The strong rotating winds of a tropical cyclone are a result of the conservation of angular momentum imparted by the Earth’s rotation as air flows inward toward the axis of rotation. As a result, they rarely form within 5° of the equator.

Tropical cyclones are almost unknown in the South Atlantic due to consistently strong wind shear and a weak Intertropical Convergence Zone. Also, the African easterly jet and areas of atmospheric instability which give rise to cyclones in the Atlantic Ocean and the Caribbean Sea, along with the Asian monsoon and Western Pacific Warm Pool, are features of the Northern Hemisphere and Australia.

Why the east coast of India is more prone to cyclone rather than the west coast?

Causes:

The Indian subcontinent is one of the worst cyclone-affected areas in the world. Unfortunately, almost 80 percent of the cyclones hit the eastern coast only. The reasons for this difference in hit ratio can be the following:-

(a) Temperature:- BOB(Bay of Bengal) is hotter than the Arabian sea. Hot water temperature is the basic criteria for the development & intensification of cyclones.

(b) Salinity:- Arabian sea has higher salinity than BOB. Its easier to heat & simultaneously evaporate water having lower salinity.

(c) Location:- The typhoons originating in the Pacific ocean too influences the cyclones in BOB, not the case in the Arabian sea.

(d) Movement:- According to IMD cyclones originating in the Arabian sea are believed to move northwest. So they actually move away from the Indian mainland.

Other causes:

  • Tropical easterly jet stream shifts its position wrt ITCZ(from east to west) and the tropical cyclones that get embedded in it flow towards the west that is the east coast.
  • Warmer coromandel coast due to a comparatively high sea surface temperature of Bay of Bengal that provides an ideal factor of cyclone formation.
  • The Bay of Bengal offers a lower vertical wind speed or wind shear which is ideal for a tropical cyclone to be formed.
  • Typhoons of S.China sea provide the leftover moisture to Bay Of Bengal adding to favorable conditions.
  • East coast, unlike west coast, has no strong mountain range like the Western Ghats to block the cyclonic winds.

Why tropical cyclones hit Odisha frequently?

Because the geographical location of Odisha puts it in the prime path of the retreating Northern East monsoon during October, when the rainy season ends. The northern coasts of Andhra Pradesh, entire Odisha, Eastern Bihar, Southern part of West Bengal most of the times come in the red alert zone when retreating monsoon passes through them. That’s because the Bay of Bengal which is warmer than the Arabian Sea often experiences depression concentrated in Sea due to low pressure.

This is the cyclonic depressions of 2018.

That depression sometimes dissolves and causes heavy rain only. Otherwise, it turns into the severe cyclone and affects Odisha severely on a large scale.

See the path of these tropical cyclones over the years.

Pathway of Super cyclone 1999.

2013 cyclone Phailin pathway.

2014, Hudhud cyclone pathway.

2018, Pathway of the cyclone Titli.

One can easily notice that Odisha is most of the time the first land to be struck by the emerged cyclone. Until it passes to other areas the effects are a little bit dissolved that that of Odisha. So sadly Odisha becomes the most vulnerable state to get affected by the cyclone.

Why do paths of hurricanes, typhoons, and other tropical cyclones recurve? 

Generally, tropical cyclones, known variously as a hurricane, typhoons, etc., start out moving west then turn toward the pole of their hemisphere and finally end up moving east. This pattern is called curvature. Here is the worldwide pattern.

From the above display, it is clear that curvature has something to do with the rotation of the Earth. Local wind and temperature conditions and local topography can influence the path and produce erratic elements to the paths but the general pattern has to have a geophysical explanation.

That explanation is that a cyclone has two components of angular momenta. One is with respect to its own spin axis and the other is with respect to the spin axis of the Earth. When a body with angular momenta, such as a gyroscope, is subjected to a torque it processes; i.e., it angular momentum vector rotates. If a body with angular momentum is forced to process then it is subject to a torque. A cyclone rotates with the Earth and its angular momentum vector is kept pointing vertically because of the rising of warm air in its eye (center). The resulting torque forces the cyclone toward the pole in its hemisphere. But as the cyclone moves toward the pole it gets closer to the spin axis of the Earth. The preservation of angular momentum then results in the cyclone moving faster with respect to the pole and hence starts moving east. Its path has thus recurved.

What makes cyclone Fani special?

Timing and strength are two factors that make Cyclone Fani different from most other tropical cyclones in this time of the year. Cyclone Fani developed near the Equator and this allowed it to gather massive strength and moisture as it could travel a long distance over the sea.

Cyclone Fani, which has been classified as an extremely severe cyclone (ESC), is the 10th such cyclone to hit India in May in past 52 years. Data from the India Meteorological Department (IMD) show that the last time an extremely severe cyclone hit India in May was in 2004. The other years when such cyclones were witnessed in May are 1968, 1976, 1979, 1982, 1997, 1999 and 2001.

Generally, extremely severe cyclones hit India’s east coast in the post-monsoon season (October-December). IMD data on cyclones that hit India between 1965 and 2017 show that the country has weathered 39 extremely severe cyclones in these 52 years. Of these, nearly 60 percent (23) was between October and December.

The India Meteorological Department (IMD) classifies cyclones on the basis of the maximum sustained surface wind speed (MSW) they generate.

The Cyclones are classified as severe (MSW of 48-63 knots), very severe (MSW of 64-89 knots), extremely severe (MSW of 90-119 knots) and super cyclonic storm (MSW of 120 knots or more). One knot is equal to 1.8 kmph.

Timing and strength are two factors that make Cyclone Fani, pronounced as Foni, different from most other tropical cyclones in this time of the year. Cyclone Fani started developing around April 25 and has made landfall this morning in Odisha on the east coast.

Traversing for nearly 10 days over the sea allowed Fani to gather such strength that it is now classified as an extremely severe cyclone. Generally, tropical cyclones over the Bay of Bengal have a lifespan of four-seven days. But Cyclone Fani is different.

What makes Cyclone Fani special is its trajectory. Fani started developing around the Equator and moved upwards. The long journey allowed it to gather a lot of moisture and momentum, resulting in strong winds.

It has been observed that cyclones/hurricanes/tornados that spend a long time traveling over the sea are generally more powerful than the ones that hit the landmass within a few days.

The reason is that the longer duration at sea allows storms to gather more water and momentum and thus generate stronger winds.

Another aspect that makes Cyclone Fani special is its trajectory. Fani started developing around the Equator and moved upwards (see image below). It thus has had a much longer journey from its starting point to the point where it made landfall than other cyclones that generate in the Bay of Bengal.

Path of Cyclone Fani. It started as a depression very close to the Equator and moved northwards thereafter. (Photo: IMD)

The IMD had first predicted that Cyclone Fani would make a landfall in Tamil Nadu but the forecast was updated as the cyclone altered its course. Had Cyclone Fani made its landfall in Tamil Nadu, it was possible that its strength would have been lower than its present strength because a landfall in Tamil Nadu would have meant that Fani would have covered a shorter distance over the sea.

Most cyclones that generate exclusively in the Bay of Bengal become relatively weaker by the time they reach the Indian landmass. However, the case with Cyclone Fani is different since it developed almost close to the Equator.

The World Meteorological Organisation (WMO), a United Nations body that monitors weather conditions, had said the extremely severe Cyclone Fani will make landfall in Odisha with wind speeds of more than 170 km/h.

However, even after making the landfall, the cyclone will move north-northeastwards and strike West Bengal as a severe cyclone and is expected to hit Bangladesh on May 4 as a cyclonic storm.

This means that besides having covered a long journey over the sea (during which Cyclone Fani collected a massive amount of moisture), the cyclone will also travel considerable distance over the land.

The timing of Cyclone Fani is important because the cyclone started developing in April, a month that has historically seen very few cyclones that were categorized as extremely severe.

Between 1965 and 2017, India was hit by 145 cyclonic storms that were classified as a severe, very severe, extremely severe and super cyclonic storm. Of these, only seven (5 percent) were in April and 27 (18 percent) in May.

Most of these cyclones (90 i.e. 62 percent) were generated between October and December.

Even after making the landfall, the cyclone will move north-northeastwards and strike West Bengal as a severe cyclone and is expected to hit Bangladesh on May 4 as a cyclonic storm.

Madhavan Rajeevan, secretary in the Ministry of Earth Sciences in a tweet said, “In the past (1891-2017) only 14 severe tropical cyclones were formed in April over the Bay of Bengal and only one storm crossed the Indian mainland. Cyclone Fani is the second storm forming in April and crossing the mainland. The last time it happened was Cyclone Nargis that devastated Myanmar in 2008.”

In the past (1891-2017) only 14 severe tropical cyclones formed in APRIL over Bay of Bengal Only one storm crossed the Indian main land. Cyclone FANI the second storm forming in April and crossing the main land. Last severe cyclone NARGIS in 2008 devastated Myanmar

According to the India Meteorological Department, “Out of 10 recorded cases of very heavy loss of life (ranging from about 40,000 to well over 2,00,000) in the world due to tropical cyclones, nine cases were in the Bay of Bengal and the Arabian Sea.”

Five of these were in Bangladesh, three in India and one in Myanmar.

World’s highest recorded storm tide measuring 45 feet occurred in 1876 during the Bakherganj cyclone near Meghna Estuary, Bangladesh.

In fact, IMD says that the world’s highest recorded storm tide measuring 45 feet occurred in this region. It was way back in 1876 during the Bakherganj cyclone near Meghna Estuary, Bangladesh.

The Indian subcontinent is considered to be one of the worst-affected regions by tropical cyclones. The region has witnessed some of the deadliest cyclones in world history.

According to the Nation Cyclone Risk Mitigation Project (NCRMP), the Indian subcontinent is exposed to “nearly 10 percent” of the world’s tropical cyclones. NCRMP’s data analysis shows that between 1980 and 2000, on an average annually 370 million (37,00,000) people were exposed to cyclones in India.

A 2014 report of the World Meteorological Organisation, a United Nations organization on weather monitoring, states that cyclonic storms have been the main cause of deaths due to natural disasters in Asia between 1970 and 2012. A majority of these cyclone-related deaths have occurred in India and Bangladesh.

When it comes to deaths, cyclonic storms were responsible for 76 percent of all deaths caused by natural disasters in Asia in this period. (The report estimates 9.15 lakh deaths were caused due to natural disasters in Asia and 6.95 of them were related to tropical cyclones.)

The top three deadliest disasters in this period were all tropical cyclones. Two of them hit Bangladesh (in 1970 and 1991) and one hit Myanmar (Cyclone Nargis in 2008). The total deaths caused by just these three cyclones was 5,77,232.

Source: World Meteorological Organisation

Of the 10 most severe natural disasters (in terms of deaths) that struck Asia between 1970 and 2012, eight were tropical storms that hit India, Bangladesh, and Myanmar.

In terms of economic loss, Asia suffered a loss of $789.8 billion in these 42 years and 30 percent of it was due to cyclonic storms.

Taking a global picture, the 10 deadliest disasters that hit the world between 1970 and 2012 included three cyclones in Bangladesh and one in Myanmar.

In fact, the 1970 cyclone in Bangladesh caused the greatest number of deaths (3 lakh) in any natural disaster in the world. The Bangladesh cyclone shared the top place with the 1983 drought in Ethiopia that killed the same number of people.

Besides this, analysis of the WMO data shows that between 1970 and 2012, 7,77,861 people were killed due to storms (cyclones/hurricanes/tornadoes). However, 89 percent of the deaths (6.95 lakh) were caused in Asia, and primarily in Bangladesh, Myanmar, and India.

How cyclones cause damage?

Cyclones are powerful storms that generate strong windspeeds and have the potential to trigger sudden and heavy rain in the affected areas. There are basically three aspects related to cyclones that have the potential to cause destruction-flooding due to the rising sea, the destruction caused by strong winds and damage due to heavy rains.

Between 1970 and 2012, 7.77 lakh people were killed due to storms cyclones/hurricanes/tornadoes) world over. But, 89% of these deaths (6.95 lakh) were caused in Asia, and primarily in Bangladesh, Myanmar, and India.

When a cyclone is formed over the sea, it generates strong winds along with it. These winds have the potential to generate storm surges. A storm surge is an abnormal rise in the sea level due to a storm (cyclone, hurricane, etc).

A storm surge becomes dangerous because it has the potential to flood low-lying areas along the coast. It can drown humans and animals, destroy infrastructure and damage the environment by eroding beaches, flooding vegetation, among others.

The second dame-causing aspect of cyclones is the strong winds that are generated by the storm. These strong winds that accompany cyclones can uproot trees, electricity poles, shatter houses, etc. This is a common phenomenon in the United States of America which regularly weathers strong hurricanes.

The third aspect with cyclones is their ability to cause sudden, heavy and prolonged rain in the affected areas. This causes floods in rivers, pollutes drinking water and if combined with storm surge, it becomes a double whammy.

The 1999 cyclone in Odisha (then Orissa) killed more than 9,000 people and was one of the worst disasters in recent Indian history.

Unfortunately, all three factors occur at the same time when a cyclone makes landfall. The IMD states that of three factors, it is a storm surge that is most catastrophic and causes widespread destruction. “Past history indicates that loss of life is significant when surge magnitude is three meters or more and catastrophic when five meters and above,” it says. A possible reason for this could be that not much can actually be done against rising sea waves, especially if they are more than 3 meters in height. Storm surge becomes more dangerous if their timing coincides with the timing of high tides.

East coast of India including Odisha is the more susceptible to tropical cyclones during the onset of monsoon in April and May and retreat of monsoon in the month of October and November respectively. As in each year, littoral states are encountering such natural disasters without any answers, it is for the center and state to get geared up with all sort of preparedness and prepare their financial budgets in advance to mitigate the natural calamity in near future.
