Cyclone :
Cyclone is a meteorological phenomenon, intense depressions forming over the open oceans and moving towards the land. On reaching the shores, it move into the interior of the land or along the shore lines.
Thus the Cyclones are the most powerful, destructive, dangerous atmospheric storms on the earth. The cyclone once formed may be active from days to weeks and their speed varies between 180-500 km/hour.
Occurrence :
Tropical Cyclones in the warm oceans are formed because of heat and moisture. The main requirement of formation of the tropical cyclone is that the sea surface temperature (SST) must be below 25*C. The tropical cyclones move like a spinning top at the speed of 10-30 km/hour.
Effect of Cyclone :
The damage depends on the intensity of cyclone. The damage to human life, crops, roads, transport, communications, tanks, canals, livestock could be heavy.
Cyclone Occurrence slow down the developmental activities of the area.
Cyclone Management :
1. Satellite images are used by meteorological departments for forecasting the weather conditions, which reveal the strength and intensity of the storm.
2. Radar System is used to detect the cyclone and is being used for cyclone warning.
3. For observing the exact location of cyclone, every half an hour satellite pictures are analyzed.
4. It is difficult to stop the formation of cyclones, but the effect of which is minimized by planting more trees on the coastal belt, construction of dams, dykes, embankments, wind breaks.
