Unlike typical cyclones that form over warm ocean waters, Asna originated as a deep depression over land in Gujrat and poised to intensify into a tropical cyclone over the Arabian Sea. 

  • According to IMD, only on three occasions (1976, 1964, and 1944), cyclones originated over mainland India in August and gathered strength as they entered the Arabian Sea.
  • Possible reasons: Unusual monsoon wind system, moisture from the Arabian Sea and soil moisture from the lands, warming of Indian Ocean, etc.

Tropical Cyclones

  • It is a rapidly rotating storm that begins over tropical oceans. 
  • Cyclones are classified as extratropical cyclones (temperate cyclones); and tropical cyclones.
  • Known as typhoons (China Sea & Pacific Ocean); hurricanes (Caribbean Sea & Atlantic Ocean); tornadoes (West Africa & southern USA); & willy-willies (Australia). 

In India 

  • India is exposed to nearly 10 % of the world’s tropical cyclones, which occur in May-June and October-November
  • More cyclones occur in the Bay of Bengal than Arabian Sea and the ratio is approximately 4:1.
  • However, cyclones are becoming more frequent on the western coast due to climate crisis and the warming of the Arabian Sea.
