12 News Weather Updates : Aila, Ampan, and Yas are warning of another cyclone (Ashani) in the fall. Nature, however, does not stop there. The threat of two cyclones. Certainly simultaneously. Twin cyclones or twin cyclones, as meteorologists put it!
So the country’s disaster risk has been doubled?
No. There is no such thing as fear. However, whether cyclone ‘Ashani’ will become a hurricane like its predecessor Ampan will be heavily dependent on the other.
The other is that the twin cyclone’s second incarnation is set to be born in the Indian Ocean. The point is, two cyclones in two hemispheres. Lightning north of the equator.
And the second is located south of the equator. The Andaman Sea is already under siege. By Sunday, it will have strengthened into a cyclone in three stages. The Indian Ocean’s low pressure is also causing cyclones to form quickly. That’s the nudge.
What produces twin cyclones?
Parthasarathy Mukherjee, a climate expert at the Indian Institute of Tropical Meteorology in Pune, adds, ‘Behind it is a western wind burst. At the present the westerly winds in the Indian Ocean are so powerful that it is feasible for two cyclones to form concurrently in two hemispheres. The cyclone winds in the Bay of Bengal, on the other hand, will rotate counterclockwise. In the Indian Ocean, cyclones will wind clockwise.
Two cyclones at each end, similar to scales. ‘Part of the wind is pulling the low pressure in the Andaman Sea,’ says Parthasarathy. The other part is the depression in the Indian Ocean. The stronger the depression or cyclone, the stronger the westerly winds can pull.
This isn’t the first time a double cyclone has hit.
Consider the following example. When Cyclone Fani Puri made landfall on May 3, 2019, Cyclone Lorna formed in the Indian Ocean at the same That time Lorna couldn’t clean her teeth that way. As a result, Fani evolved into a powerful cyclone. The toll has to be calculated across Orissa’s broad plateau, including Puri. It is still less likely at this moment as strong as hint, fani or ampan.
The storm’s greatest speed in the Bay of Bengal might reach 90 kilometres per hour by May 10. The greatest wind speed reached 175 km/h when the Ampan transformed into a super cyclone in the Bay of Bengal and landed on land.
The Indian Ocean plays a major part in this. A probable storm in the Indian Ocean is pulling a substantial portion of the westerly winds, as can be observed. There is no risk of threatening any town, however. Because the land in that area is limited. The starting point is at least 1,500 kilometres from Jakarta, Indonesia’s capital.
So, will the storm be classified as a minor cyclone? Or, as in Java, will there be a scarcity of water vapour in the sea? “The strength of the cyclone depends on a variety of circumstances,” Sanjeev Bandyopadhyay, deputy director general of the eastern head of Mausam Bhaban, noted. One of the requirements is that the sea level temperature be enough.
That situation is ideal. The Andaman Sea’s low pressure will bring water vapour from the Indian Ocean, as well as the Arabian Sea and the South China Sea. As a result, without further time, it is impossible to say clearly.’
It is currently unknown what he will do after leaving the position. Thunderstorms are expected to approach the Andhra Pradesh-Orissa coast, according to Mausam Bhavan.The possibilities of relocating to Bangladesh are significantly better then.
If that is the case, it will either hit Bangladesh directly or via passing through the Sundarbans like cyclone Bulbul; meteorologists are looking into all possibilities. Following a deep depression, the picture may become clearer.
