Amphan Cyclone - Timeline

Here, we have shared the timeline of events about Cyclone Amphan that will help you understand what happened during the cyclone better -

  • The super storm was conceived as a cyclonic storm over the Bay of Bengal before turning into an Extremely Severe Cyclonic Storm (ESCS) and making landfall on 20 May between Digha (in West Bengal) and Hatiara (Bangladesh).
  • After making landfall, North Odisha Coast was the most impacted, with wind intensity reaching 110-120mph. The wind intensity reached a maximum of 265 mph before weakening.
  • Vishakhapatnam's Doppler Weather Radar was utilized to track the intensity of super Cyclone Amphan.
  • The National Disaster Response Force (NDRF) monitored the cyclone alongside the National Crisis Monitoring Committee, the Indian Meteorological Committee, and the Cabinet Committee on Security.
  • The other Indian state impacted by Cyclone Amphan was Kerala, which faced heavy rainfall and was issued a yellow alert by the IMD.
  • The causes of the Amphan included the formation of an area of low pressure over the Bay of Bengal about 1020 km to the southeast of Visakhapatnam. This, along with the warm sea temperature (between 32 to 34 degrees Centigrade), became responsible for causing the cyclonic storm.
  • Amphan Cyclone, which took 40 hours to transform into a super cyclone, slowly lost its intensity on 21 May 2020. However, by this time, it had already wreaked severe damage, destroyed properties, and taken the lives of 128 people.

Cyclone Amphan - Cause

The super Cyclone Amphan originated during the cyclone season of the North Indian Ocean in May 2020. The cause of the cyclone was the development of a low pressure that disturbed the warm sea surface. It intensified and developed into a cyclonic storm in a duration of just 12 hours.

Cyclone Amphan travelled northwards towards the Bay of Bengal and made landfall on 16 May 2020, causing destruction all over. It affected parts of Odisha, West Bengal, and Bangladesh as well.
