Answer 1

Hey Friends,
_______________________________

As we all know India falls in the monsoon climatic region. Rainfall is the backbone of Indian agriculture and economic activities. Below we will have a look at the key features of Indian monsoon as well as its distribution pattern.

Features of Rainfall in India

Rainfall in India mainly occurs in the months of July, August and September.

The Indian rains are chiefly orographic in nature. As a result, the regions situated on the windward side receive greater rainfall than the regions located on the leeward side.

Only a scant amount of rainfall is received from cyclones and convectional rainfall.

Monsoon in India is irregular, not well distributed and unpredictable. While there are floods in some regions, the other regions face drought.

Most parts of the India do not receive rainfall during the winter season. Some areas which receive rainfall during the winters are –

Central and northern parts of India get occasional rainfall during winter.

Weak temperature cyclones lead to rainfall in Delhi, Haryana, Punjab and western Uttar Pradesh. This rainfall benefits the rabi crops.

Northeastern areas of the country also receive winter rainfall.

In October and November, northeast monsoon receives heavy  moisture while blowing over the Bay of Bengal and cause enormous rainfall over the coast of Tamil Nadu and the southern tip of Andhra Pradesh.
