Cyclone Asani – formed in the Andaman Sea – is now located in the Bay of Bengal. Another depression, on the other hand, has formed in the Indian Ocean – this too could turn into a “cyclone”, fears the Indian Meteorological Department, saying that the Cyclonic Storm Asani could take a terrible form due to the effect of the new cyclone.     

At the center of the Cyclone Asani, the maximum wind speed is rising to 117 kmph. At present, it is moving towards the coast at a speed of 25 kmph.

According to the Indian media, quoting the Indian Meteorological Department, it is not yet clear whether the “twin cyclones” will accelerate the speed of the Cyclonic Storm Asani — because it depends on the strength of the other depression.

It is learned that the Cyclone Asani is located North of the Equator. Besides, the depression located South of the Equator will be intensified further, fearing the formation of another cyclone.   

Meteorologists say Asani, on the one hand, will evaporate water vapor from the Andaman Sea, on the other hand, the new depression will draw “water vapor” from the Indian Ocean. There will be a “lot of stretch” between the two. As a result, on the one hand, as the “wind flows in a clockwise direction”, on the other hand, it will also “rotate counterclockwise” — whichever pulls the air more, the more energy it will have.

Twin cyclones are nothing new. Three years ago, on May 3, 2019, when Cyclone Fani formed in the Bay of Bengal, Cyclone Lorna formed in the Indian Ocean at the same time. However, because Lorna was not strong, Fani intensified into an extremely severe cyclone.

Bangladesh meteorologists could not say much about this. Sanaul Haque Mondal, deputy director of the Bangladesh Meteorological Department (BMD), said they were currently monitoring the cyclone. They will monitor the situation when the depression in the Indian Ocean turns into a cyclone and moves towards the coast. “There is almost no danger of such a distant storm affecting Bangladesh,” he added.

Gowhar Naeem Wara, a cyclone and disaster management analyst, said the “twin cyclones were, in fact, a matter of concern”. However, the Indian ocean is far away. There will be a storm and it will take a long time to reach the coast through the Bay of Bengal. Even though it will rain heavily at that time, the strength of the storm was “greatly reduced”, he also said.

Mentioning that when there is a storm during the full moon, the water level rises normally, Gowhar Naeem Wara said the next full moon on May 16. At that time, there is a fear of at least three to four feet more tidal waves than the normal tide if a storm takes place on the coast

“It’s hurricane season,” he said, adding, “It is not uncommon for twin cyclones to form. But meteorologists now have to decide which will be stronger, or which will have an effect.”

Meteorologist Kh. Hafizur Rahman said the strong cyclone ASANI located in the West-Central Bay of Bengal and adjoining Southeastern Bay of Bengal has moved to the northwest and is located in the West-Central Bay of Bengal and adjoining areas. It is now located 1085 kms South-Southwest from Chattogram seaport on Monday (May 9) at 6 am, 1020 kms South-Southwest from Cox’s Bazar seaport, 1020 kms South-Southwest from Mongla seaport and 995 kms South-Southwest from Payra seaport. “It is likely to move further Northwest,” he added.

Within 64 kms of the strong cyclone center, the maximum continuous wind speed is 89 kmph, which is increasing up to 117 km in the form of gusts or gusts of wind. The sea is very rough near the epicenter of the cyclone.

Therefore, Chattogram, Cox’s Bazar, Mongla and Payra seaports have been asked to display a distant warning signal no. 2 (two).

Besides, all fishing boats and trawlers stationed in the North Bay have been asked to proceed cautiously from near the coast. At the same time, they have been told not to venture into the deep sea.

The way a cyclone forms

Cyclones are usually formed out of depression. If the sea surface temperature rises in the equatorial region, then warm and humid air becomes lighter and rises, creating a void. To fill that void, cold air from the polar region rushed toward the equator. However, this air does not flow directly. As the earth revolves around its own axis, a force is created that causes the wind to bend south to the northern hemisphere and north to the southern hemisphere. This wind, which blows at a high speed, creates a whirlwind, which we call a cyclone or a hurricane.
