Indian Monsoon

Rain occurs on the windward side of a mountain while the leeward side remains relatively dry. For exams the interior Deccan can be taken as an example.

Low monsoon rainfall can affect crop production and water storage. For exams connect monsoon with agriculture and water resources.

Withdrawal of monsoon generally starts from northwest India. For exams remember onset from the south and withdrawal from the northwest.

During monsoon winds from the sea bring water vapour. For exams understand moist winds as the reason for higher humidity.

El Nino and Southern Oscillation can affect the strength and rainfall of monsoon. For exams connect them with monsoon variability.

During retreating monsoon the Bay of Bengal can become prone to cyclones. For exams connect this period with cyclones on the eastern coast.

The Bay branch enters from the northeast and gradually moves westward across the Ganga plain. For exams understand its route through a map.

Unequal heating of land and sea creates pressure difference and changes wind direction. For exams remember pressure gradient as the cause of wind.

Monsoon rainfall is not uniform or constant so it shows variability. For exams connect both drought and flood with this feature.

Kharif crops are sown with the arrival of monsoon and benefit from rainfall. For exams consider kharif as the crop of rainy season.

Tamil Nadu and the Coromandel Coast receive important rainfall from retreating monsoon. For exams remember autumn rainfall on the eastern coast.

Excessive monsoon rainfall can cause floods in rivers and low-lying areas. For exams remember both benefits and risks of monsoon.

Low monsoon rainfall can reduce soil moisture and water sources. For exams connect weak monsoon with possibility of drought.

A map clearly shows the routes of Arabian Sea and Bay branches and rainfall distribution. For exams remember routes for map-based questions.

Due to low rainfall western Rajasthan has arid and semi-arid conditions. For exams connect the Thar region with low rainfall.

The southwest monsoon generally enters India through the Kerala coast. For exams consider Kerala as a key indicator of monsoon onset.

Monsoon affects farming, water supply and economic activities in India. For exams link monsoon with both life and economy.

Winds from the sea bring water vapour which causes monsoon rainfall. For exams understand moist winds as the basis of rainfall.

Before monsoon intense heat and hot dry winds strengthen low pressure. For exams connect northwest India's heat with monsoon attraction.

Timely rainfall helps sowing and crop growth. For exams connect timely monsoon with agricultural success.
