A Terminology used for classification of tropical depressions in the South-West Indian Ocean
AREA OF DISTURBED WEATHER
Area of low pressure without organization
TROPICAL DISTURBANCE
Low Pressure area with enhanced convection and a cyclonic wind circulation to be not exceeding 27 kts ( 50 km/h)
TROPICAL DEPRESSION
Low Pressure area with organized convection and definite cyclonic wind circulation in which the maximum of the average wind speed is estimated to be in the range 28 to 33 kts (51 to 62 km/h)
MODERATE TROPICAL STORM
System in which the winds near the centre is estimated between 34 to 47 kts (63 to 88 km/h)
SEVERE TROPICAL STORM
System in which the winds near the centre is estimated between 48 to 63 kts (89 to 117 km/h)
TROPICAL CYCLONE
System in which the winds near the centre is estimated between 64 to 89 kts (118 to 165 km/h)
INTENSE TROPICAL CYCLONE
System in which the winds near the centre is estimated between 90 to 115 kts (166 to 212 km/h)
VERY INTENSE TROPICAL CYCLONE
System in which the winds near the centre is estimated to exceed 115 kts (212 km/h)
SUBTROPICAL DEPRESSION
An hybrid system having during its life some characteristics which could belong to both tropical and extra-tropical depressions. In the South-West Indian Ocean, the genesis of such system is regulary observed over the South of Mozambique channel
* The wind speed is the mean wind over 10 minutes
