Deep depression - A depression is<br />

classified as a deep depression when it has<br />

maximum sustained winds between 27 kn<br />

(51 km/h, 31 mph) and 33 kn (61 km/h,<br />

38 mph<br />

Cyclonic storm- If its sustained winds reach<br />

34 kn (62 km/h, 39 mph) a tropical system is<br />

classified as a cyclonic storm<br />

Severe cyclonic storms- In cases where<br />

cyclonic storms possess wind speeds<br />

greater than 48 kn, (88 km/h, 55 mph), they<br />

are classified as severe cyclonic storms.<br />

Very severe cyclonic storm- A severe<br />

cyclonic storm is labelled as a very severe<br />

cyclonic storm when it reaches wind speeds<br />

greater than 64 kn, (118 km/h, 74 mph).<br />

Super cyclonic storm – It is the highest<br />

category that the India Meteorological<br />

Department uses in its <strong>scale</strong>, and is used to<br />

refer to tropical cyclones that have maximum<br />

sustained winds exceeding 120 kn,<br />

(222 km/h, 138 mph). IMD then made<br />

another change in 1998 to introduce a<br />

category for super cyclonic storms which are<br />

cyclonic storms with wind speeds <strong>of</strong> more<br />

than 120 kts, (222 km/h, 138 mph).<br />
