Cyclone Biparjoy to stretch nearly 10 days Arabian Sea cyclones are lasting longer
It is learnt that Cyclone Biparjoy is likely to stretch nearly 10 days with Arabian Sea cyclones to last longer.
Biparjoy, which formed into a cyclonic storm on June 6, is expected to hit the Kutch coast after having existed as a cyclone over the Arabian Sea for nearly 10 days.
This makes it one of the longest lasting cyclones to impact India in recent decades.
As per reports, the cyclonic storms over the Arabian Sea are emerging more frequent and severe under the influence of global warming. The same study also found that cyclones were persisting for longer periods in Arabian Sea, increasing the chances of more severe storms.
Scientists at Pune’s Indian Institute of Tropical Meteorology claim that
there has been an 80% increase in duration of cyclones in the Arabian Sea in the last four decades, with the duration of very severe cyclones having increased by 260%, and the changing status of tropical cyclones in the north Indian Ocean”, by scientists at Pune’s Indian Institute of Tropical Meteorology.
Reportedly, according to
Roxy Mathew Koll from IITM, one of the authors of the study.
Duration of a cyclone impacts the number of fishing days in the open sea. Such fishing usually takes place in the pre- and post-monsoon months. Higher frequency.
The longer a cyclonic storm remains over the sea the more energy and moisture it is likely to accumulate, increasing the chances of the storm becoming more severe and causing destruction after landfall.
Biparjoy, which is currently an extremely severe cyclonic storm in terms of intensity, has been moving at a particularly slow rate because of steering winds and anti-cyclonic circulations on either side of the system. That’s one of the reasons why it was difficult to predict where the cyclone would make landfall,” said India Meteorological Department chief Mrutyunjay Mohapatra.
The IITM study too had found that the translation speed of cyclones – the speed at which a cyclone moves – had decreased in the Arabian Sea. It also reported a 52% increase in the number of cyclones in the Arabian Sea since 1982, along with a 150% increase in very severe cyclones.
At the same time, the number of cyclones in the Bay of Bengal had decreased by 8%.
