Answers
Different regions of the world use different scales to measure and classify storms and winds caused by depressions.
The Indian Meteorological Department monitors and classifies tropical cyclones within the Indian Ocean and uses a scale ranging from 1 to 7, estimating minimum 3-minutes sustained winds.
Scale 1 is 31 – 50 kilometres/hour winds (Depression)
Scale 2 is 51 – 62 kilometres/hour winds (Deep depression)
Scale 3 is 63 – 88 kilometres/hour winds (Cyclonic storm)
Scale 4 is 89 – 117 kilometres/hour winds (Severe cyclonic storm)
Scale 5 is 118 – 165 kilometres/hour winds (Very severe cyclonic storm)
Scale 6 is 166 – 220 kilometres/hour winds (Extremely severe cyclonic storm)
Scale 7 is > 221 kilometres/hour winds (Super cyclonic storm)
The Saffir-Simpson Hurricane Wind Scale (SSHWS) classifies hurricane and tropical storms in the western hemisphere on a scale of 1 – 5.
The Japan Meteorological Agency (JMA) monitors tropical cyclones within the northern hemisphere.
