Every year, during the pre-monsoon season, tropical storms form in the Bay of Bengal (BoB) and hit the eastern coast of India, affecting the lives of people living in the coastal region. On 3 May 2019, deadly cyclone Fani impacted coastal areas of Odisha (eastern province) causing large scale damage and the impact was observed up to the Eastern Himalayan region. Detailed analyses of satellite, ground, and Argo data have provided information about the changes on land due to floods caused by heavy precipitation, weather conditions, atmospheric, and ocean parameters. Pronounced changes in ocean and atmospheric parameters were observed at the time of the formation of the cyclone and its movements towards the land, especially along its track. Changes in ocean parameters such as chlorophyll concentration, dissolved oxygen, salinity, and sea surface and sub-surface temperature are found to be associated with the cyclone Fani. Our analysis shows a strong coupling between the land-ocean-atmosphere associated with the cyclone Fani.
