Indian Climate and Seasons

Southern slopes in the Himalayan region receive more direct and longer sunlight exposure compared to northern slopes, which are often in shadow. This greater solar radiation supports thicker, more diverse vegetation. Northern slopes receive less sunlight and remain cooler, supporting less dense vegetation cover.

The western slopes of the Western Ghats receive significantly heavier rainfall from the southwest monsoon winds than the eastern slopes. This orographic rainfall occurs when moisture-laden air from the Arabian Sea is forced upward by the mountain barrier, cooling and condensing on the windward (western) side. The eastern slopes lie in the rain shadow area and receive much less precipitation.

The southwest monsoon arrives in India by early June and typically withdraws by late September. This period brings 70-80% of India's annual rainfall.

India receives most of its annual rainfall during the southwest monsoon season, which typically brings heavy rains from June to September. This period accounts for about 75-80% of India's annual rainfall. January-April is generally dry, September-December sees the retreating monsoon in some regions, and February-March is typically dry.

India receives an average annual rainfall of about 105 cm, primarily from the southwest monsoon. This varies widely across regions from <10 cm in Rajasthan to >250 cm in the northeast.

West Bengal's hot and humid climate (1) and annual flood-deposited silts (2) directly enable jute cultivation by providing ideal growing conditions and natural fertilization. While mill concentration (3) and coastal location (4) support the industry, they don't cause production itself.

Madras (now Chennai) receives winter rainfall from the Northeast Monsoon, which occurs from October to December. These winds blow from the northeast, pick up moisture from the Bay of Bengal, and release it along the Tamil Nadu coast. The Southwest Monsoon (June-September) bypasses this region due to the Western Ghats.

Tamil Nadu lies in the rain shadow area of the Western Ghats during the southwest monsoon (June-September). The moisture-laden winds shed most of their rainfall on the western side (Kerala), leaving Tamil Nadu relatively dry.

During southwest monsoon, the Western Ghats block the moisture-laden winds, causing heavy rainfall on the windward side (west coast). Tamil Nadu, located on the leeward (eastern) side, receives very little rainfall as it lies in the rain shadow area.

The Tropic of Cancer (23.5°N) passes through the middle of India, dividing the country into two climatic zones. The southern half, being closer to the equator, experiences a tropical climate with high temperatures throughout the year. The northern half, being farther from the equator and more influenced by continental factors, has a more varied climate including temperate conditions in some regions.

During the southwest monsoon season, a low pressure system develops over northwestern India. This low pressure area is a key feature of the monsoon circulation, drawing moist air from the Indian Ocean and causing the characteristic heavy rainfall associated with the monsoon.

During the post-monsoon season in India, the pressure gradient becomes slack (weak). This occurs because the monsoon trough weakens and the temperature contrast between land and sea reduces, leading to reduced pressure differences and generally calmer weather conditions.

Thiruvananthapuram is a place located in the state Kerala, which receives maximum rainfall during the month of June.

Jammu hills receive adequate rainfall (>100 cm annually) due to their location and elevation. Mikir hills in Assam also receive high rainfall typical of the Northeast region. However, Zaskar range (in Ladakh) is a high-altitude cold desert receiving very low precipitation (<10 cm annually), well below 100 cm. Therefore only statements 1 and 2 are correct.

Mawsynram in Meghalaya holds the Guinness World Record for highest average annual rainfall at approximately 11,872 mm. It receives more rainfall than Cherrapunji (also in Meghalaya), which previously held the record. Guwahati, Munnar, and Darjeeling receive significant rainfall but nowhere near Mawsynram's levels.
