three controls affecting the climate of India

Answer: The main factors which affect the climate of India are:

  • Latitude

  • Altitude

  • Pressure and Winds


The Tropic of Cancer divides the Indian subcontinent equally in two parts

  1. Tropical climate: This is the climate predominant between the equator and Tropic of Cancer. Unlike the subtropics, where there are significant variations in day length and temperature with season, tropical temperature remains relatively constant throughout the year and seasonal variations are dominated by precipitation.

  2. Subtropical climate: Sub-tropical climate covers most of the Northeast India.


As the altitude increase the atmosphere becomes less dense and temperature decreases that is the reason why hills are cool even during summer.

India has an average height of 6000 meters in the north. In the south along the vast coastal area the maximum elevation is 30 meters. It is because of these differences in altitudes relief Plains of Punjab, Haryana, and UP etc. are too hot during summer and Nainital, Darjeeling, and Ooty like mountains places are cool.

Pressure and Winds

  • India situated in the region of north-easterly winds which blow from sub-tropical high pressure belt of northern hemisphere.

  • Monsoon: Because of the low pressure conditions created in the nearby areas like East Iran, and Central Asia, Tibet, Africa, fury of monsoons and long dry spell happen in India.
