The seasonal reversal of wind direction occurs over the Indian subcontinent due to differential heating. During summer, land heats faster, creating low pressure, while the oceans maintain higher pressure. This pressure contrast establishes a monsoon trough, attracting moisture-laden winds from the Indian Ocean—known as the southwest monsoon. In winter, the land cools faster, forming high pressure, leading to winds flowing from land to sea—the northeast monsoon. These seasonal pressure differences prompt the reversal of wind patterns, causing the distinct southwest and northeast monsoons.
The bulk of rainfall in India occurs primarily within a few months due to the monsoonal nature of the country's climate.

The bulk of rainfall in India occurs primarily within a few months due to the monsoonal nature of the country’s climate. The southwest monsoon, active from June to September, brings the majority of annual rainfall. This concentrated rainfall is a result of the seasonal winds carrying moisture-laden air from the Indian Ocean. The monsoon’s abrupt onset and gradual withdrawal, coupled with India’s topographical features, lead to the concentration of heavy rainfall within this limited period, impacting agriculture and water resources significantly.
The Tamil Nadu coast experiences winter rainfall due to the retreating northeast monsoon. As the southwest monsoon weakens by September, the northeast monsoon winds blow from land to sea, carrying moisture from the Bay of Bengal towards the coast during October to December.

The Tamil Nadu coast experiences winter rainfall due to the retreating northeast monsoon. As the southwest monsoon weakens by September, the northeast monsoon winds blow from land to sea, carrying moisture from the Bay of Bengal towards the coast during October to December. The Eastern Ghats influence these winds, causing them to ascend and release moisture as rainfall along the Tamil Nadu coast. This winter rainfall phenomenon is a result of the retreating monsoon winds, benefiting the region during the post-monsoon period.
The delta region of the eastern coast faces frequent cyclones due to various factors. Its proximity to the Bay of Bengal exposes it to cyclones originating from warm ocean waters. Low-lying terrain and flat topography make delta areas, like the Ganges-Brahmaputra and Godavari deltas, susceptible toRead more
The delta region of the eastern coast faces frequent cyclones due to various factors. Its proximity to the Bay of Bengal exposes it to cyclones originating from warm ocean waters. Low-lying terrain and flat topography make delta areas, like the Ganges-Brahmaputra and Godavari deltas, susceptible to storm surges and flooding during cyclones. The confluence of rivers and the deltaic formation further exacerbates the region’s vulnerability, leading to frequent cyclone impacts and significant damage along the eastern coast.
Parts of Rajasthan, Gujarat, and the leeward side of the Western Ghats face drought due to various factors. The leeward side of the Western Ghats experiences reduced rainfall due to the rain shadow effect—dry air descending after moist air releases precipitation on the windward side. Additionally, rRead more
Parts of Rajasthan, Gujarat, and the leeward side of the Western Ghats face drought due to various factors. The leeward side of the Western Ghats experiences reduced rainfall due to the rain shadow effect—dry air descending after moist air releases precipitation on the windward side. Additionally, regions in Rajasthan and Gujarat are far from moisture sources, receiving limited rainfall. These areas, characterized by arid landscapes and sparse vegetation, face high temperatures and low precipitation, making them prone to recurrent droughts.
