The answer is All 1, 2 and 3 Explanation & Key Takeaways: The influence of the Lattitude, Altitude and Pressure is given as follows Latitude • The Tropic of Cancer passes through the middle of the country from the Rann of Kuchchh in the west to Mizoram in the east. • Almost half of the country, lying south of the Tropic of Cancer, belongs to the tropical area. • All the remaining area, north of the Tropic, lies in the sub-tropics. • Therefore, India’s climate has characteristics of tropical as well as subtropical climates. Altitude • India has mountains to the north, which have an average height of about 6,000 metres. • India also has a vast coastal area where the maximum elevation is about 30 metres. • The Himalayas prevent the cold winds from Central Asia from entering the subcontinent. • It is because of these mountains that this subcontinent experiences comparatively milder winters as compared to central Asia. Pressure and Winds • India lies in the region of northeasterly winds. • These winds originate from the subtropical high-pressure belt of the northern hemisphere • The pressure and wind conditions over India are unique. During winter, there is a high-pressure area north of the Himalayas. Cold dry winds blow from this region to the low-pressure areas over the oceans to the south. • In summer, a low-pressure area develops over interior Asia, as well as, over northwestern India. This causes a complete reversal of the direction of winds during summer. Air moves from the high-pressure area over the southern Indian Ocean, in a south-easterly direction, crosses the equator and turns right towards the low-pressure areas over the Indian subcontinent. • These are known as the Southwest Monsoon winds. • These winds blow over the warm oceans, gather moisture and bring widespread rainfall over the mainland of India
