the super cyclone which slammed orissa in 1999 was with an approximate wind speed of
1999 Odisha cyclone The 1999 Odisha cyclone (IMD designation BOB 03,[1] JTWC designation 05B[3]) was the strongest recorded tropical cyclone in the North Indian Ocean and among the most destructive in the region.[note 1] The 1999 Odisha cyclone organized into a tropical depression in the Andaman Sea on 25 October, though its origins could be traced back to an area of storms in the Sulu Sea four days prior. The disturbance gradually strengthened as it took a west-northwesterly path, reaching cyclonic storm strength the next day. Taking advantage of highly favorable conditions, the storm rapidly intensified, attaining super cyclonic storm intensity on 28 October before peaking with winds of 260 km/h (160 mph) and a record-low pressure of 912 mbar (hPa; 26.93 inHg). The storm maintained this intensity as it made landfall on Odisha on 29 October. The cyclone steadily weakened due to persistent land interaction and dry air, remaining quasi-stationary for two days before slowly drifting offshore as a much weaker system; the storm dissipated on 1 November over the Bay of Bengal.
Tropical cyclone windspeed climatology The strongest winds in a northern hemisphere tropical cyclone is located in the eyewall and the right front quadrant of the tropical cyclone. Severe damage is usually the result when the eyewall of a hurricane, typhoon or cyclone passes over land. The right front quadrant is also an area of a tropical cyclone were the winds are strongest. The reason that the winds are at the front right side of a storm in the northern hemisphere (and the front left hand side in the Southern Hemisphere) is because of the motion of a tropical cyclones motion contributing to its rotation. A 100 mph hurricane while stationary, might have winds of 100 mph on its right side in the northern hemisphere while the rest of the storm might have winds at 70 mph. The location of the right ( or left in the Southern Hemisphere) front quadrant also depends on the storm track. For example, in the northern hemisphere, if the storm was moving west, then the right side is to the north, if it moving north, then the strongest winds will be to the east of the center. [5]
