Cyclone Asna will cause havoc!
An unusual cyclone in the Arabian Sea after crossing the Gujarat coast has surprised meteorologists. Meteorologists have described it as a rare phenomenon and said that for the first time since 1976, a cyclone has formed in the Arabian Sea after crossing land, challenging the long-held understanding of cyclone formation in the region. Scientists say that in 1976 a cyclone started over Odisha, moved west-northwest, entered the Arabian Sea. That storm followed a looping track, and weakened over northwest Arabian Sea near the Oman coast.
Why are scientists surprised about Asana
Weather scientists have described the timing of Cyclone Asan as particularly surprising. Usually, the temperature of the Arabian Sea remains below 26 degrees Celsius during the monsoon season, making cyclone formation unlikely between July and September. A deep depression is a low-pressure system with wind speeds ranging from 52 kmph to 61 kmph, while a cyclone has wind speeds between 63 kmph and 87 kmph, scientists said. For cyclogenesis to occur, the sea surface temperature must be above 26.5 degrees Celsius.
Scientists are looking for the reasons
The western Arabian Sea is generally unfavorable for cyclone formation due to cool ocean temperatures and dry air from the Arabian Peninsula. These conditions are in stark contrast to the more cyclone-friendly environments of the Bay of Bengal and the eastern Arabian Sea. Historically, the northern Indian Ocean, which includes both the Bay of Bengal and the Arabian Sea, has had about five cyclones each year. The Bay of Bengal typically has four times as many cyclones as the Arabian Sea, with most occurring between May and November.
Madhavan Rajeevan, former secretary of the Ministry of Earth Sciences, expressed surprise at the magnitude of the cyclone and questioned whether global warming could be influencing these unusual conditions. The intensity of this system challenges conventional understanding of the region’s meteorology and raises important questions about changing climate patterns.
Global warming is not the reason
Scientists said that the occurrence of cyclone Asna at this time is an unprecedented event and this unprecedented event points to the urgent need for more research on the changing dynamics of cyclogenesis in the Arabian Sea. Meteorologists are now faced with the challenge of understanding how global warming may alter established weather patterns and cyclone formation processes in this region.
As climate change continues to impact global weather systems, events like the Arabian Sea cyclone point to possible long-term changes in tropical storm behaviour. The scientific community will closely monitor the development of this cyclone and analyse its implications for future weather predictions and climate models in the region.
