Rainfall pattern
Explanation :
Rainfall patterns are decided by the prevailing wind patterns. In large parts of India, rains are mostly brought by the southwest or north-east monsoons. know that the depressions in Bay of Bengal also cause rain at some places of India ?
India gets near about 3 trillion m³ of water from rainfall (or precipitation which amounts for 1405-117cm. annually). Its intensity is different in different zones. On the basis of intensity of rainfall, zones are classified as :
(a) Wet zone : with very high rainfall
(b) Intermediate zone : with heavy rainfall
(c) Semi-arid zone : with moderate rainfall
(d) Arid zone : with low rainfall.
Let us discuss the different types of precipitation.
Different Types of Precipitation (figure.) : There are four main types of precipitation as follows :
(a) Rain : It is the precipitation in the form of liquid
(b) Sleet : It is the rain which freezes.
(c) Snow : It is the small ice crystals that form around dust or salt particles.
(d) Hail : It is the frozen rain that is circulated up and down in a cloud until, it is hard frozen ball of ice.
Cloudy, wet, changeable weather is common in low pressure zones with rising unstable areas. Such conditions are found at temperate latitudes, where warm air rises along polar fronts. Here, spiraling low pressure cells known as depressions (mid-latitude cyclones) are formed. In India, most of the rains are brought by southwest or northeast monsoon.
