Q1: Explain wind storms and cyclones along with their effects?
View Answer
Ans:
A windstorm is just a storm with high winds or violent but with little or no rain.
The main effects of tropical cyclones include heavy rain, strong wind, large storm surges at landfall, and tornadoes. The destruction from a tropical cyclone depends mainly on its intensity, its size, and its location.
Severe tropical cyclones are responsible for large number of causalities and considerable damage to property and agricultural crop. The destruction is confined to the coastal districts and the maximum destruction being within 100 km from the centre of the cyclone and on the right side of the storm track. Principal dangers from cyclones are: (i) very strong winds, (ii) torrential rain, and (iii) high storm tides.

Q2: Explain how we can find wind direction at a given place.

Ans:
We can find the wind direction using a Wind Vane or Weather Vane or Weather Cock. It consists of a flat metallic sheet generally cut into shape of a cock or arrow which is mounted on disk and free to move around a axial shaft and point in the direction of wind . They are typically used as an architectural ornament to the highest point of a building. Alsowe can find the direction of light wind using smoke from incense sticks. The direction of smoke will indicate the wind direction.
