Detailed explanation-1: -During the winter season, cool, dry winds blow from north to the south. The sun rays do not fall directly into the region as a result, the temperatures are quite low in northern India.
Detailed explanation-2: -This position of the earth is referred to as the Winter Solstice. The direct rays of the sun fall on the equator on 21st March and 23rd September. At this position, the whole earth experiences equal days and equal nights since neither of the poles are tilted towards the sun.
Detailed explanation-3: -During January February, the Northern Hemisphere faces away from the Sun, and the vertical rays of the Sun fall between the Tropic of Capricorn and the Equator. Tamil Nadu is near the Equator and receives slant rays of the Sun, leading to cold weather in India.
Detailed explanation-4: -The sun’s rays extend to the North and South Poles equally only twice during the year, on September 23 and March 21. On these two days, the vertical rays of the Sun fall directly on the Equator.
Detailed explanation-5: -During the winter season, the sun rays fall indirectly in the region.
