Master Data: Year, Month and Season-wise Frequency of Cyclonic Disturbances, Cyclones and above and Severe Cyclones and above over Bay of Bengal, Arabian Sea and Land

This Dataset contains year, month and season-wise frequency of Cyclonic Disturbances, Cyclones and above and Severe Cyclones and above over Bay of Bengal, Arabian Sea and Land. Note: 1) Cyclones and above: A cyclonic disturbance in which the maximum average surface wind speed is in the range of 34 to 47 knots (62 to 88 kmph). 2) Cyclonic Disturbances: A non frontal synoptic scale low pressure system originating over tropical waters with organized convection and definite cyclonic wind circulation. It is called as a depression if the associated sustained maximum wind speed at surface level is 17-27 knots. It is called as a deep depression if the sustained maximum wind speed is 28-33 knots. 3) Severe Cyclone and above: A cyclonic disturbance in which the maximum average surface wind speed is in the range of 48 to 63 knots (89 to 117 kmph).
