About Super cyclonic storm:
Amphan intensified from a Category-I cyclone to a Category-5 cyclone in less than 24 hours, thus generating higher wind speed in a short duration. Rapid intensification of a storm occurs if maximum sustained wind speed increases by 55 kmph in 24 hours duration.
It is the highest category used by the India Meteorological Department (IMD) to classify tropical cyclones, within the North Indian Ocean tropical cyclone basin between the Malay Peninsula and the Arabian Peninsula.
The sea surface temperatures (SST) are usually warmer over the Bay of Bengal as compared to the Arabian Sea. This summer, prior to the formation of Amphan, temperature over the Bay of Bengal ranged between 31-34 degree Celsius, which was above the normal levels. Since the temperature is high during summer, conditions are favorable for cyclone formation.
