Why there is unequal pattern of …

Rainfall depend upon various climatic features. For example, the presence of mountains affect the distribution of rainfall. The moisture laden winds when strike the windward side of the mountains. Causes rainfall. The places located on the leeward side of the mountains get scarce rainfall. This is the reason that Mumbai receive more rainfall than Pune. North eastern India get most of its rainfall in this manner. The Eastern side of the Western Ghats or Ladakh also get scarce rainfall. Heavy rainfall is recorded in hilly and forested regions. Forested regions like Assam, the Ganga delta and the Western Ghats receive abundant rainfall. The regions falling first in the path of moisture laden winds receive more rainfall than the places that fall last. For example, Patna receive more rainfall than Delhi from the Bay of Bengal branch of Monsoon winds. The unpredictability of the monsoon along with phenomena like monsoon troughs, El-Nino and depressions lead to uneven distribution of rainfall. Of late, climatic changes because of global warming have resulted in unpredictable rainfall pattern all over the world including India.

 

Rainfall is unevenly distributed in India because of several reasons:

• Rainfall depend upon various climatic features. For example, the presence of mountains affect the distribution of rainfall. The moisture laden winds when strike the windward side of the mountains.
