Discuss the important factors that determine the climate of india
Answers
The location of India and the various relief features have deep effect in determining climate of India.
(t) Location
- India is located between 8° N to 37° N latitudes.
- Tropic of Cancer divides the country in two - equal halves— North sub-tropical zone and South tropical zone.
- *India is sorrounded by three water bodies in the south and girdled by a high continuous mountain chain in the North.
- This compact ph^ical setting gives unique and common climatic framework.
- Indian ocean, Bay of Bengal and Arabian sea have moderating effects on India’s climatic condition.
- (ii) Relief
- High mountains in the North act as barriers for cold and hot winds. It provides the whole of North India a tropical climate.
- They may also cause precipitation as they are high enough and lie in the path of rain-bearing winds. For example, the leeward side of Western Ghats remains relatively dry in monsoon season.
- The Himalayas also force the South-West mansoons to shed all their moisture in the sub-continent.
- Thus, it can be concluded that location and relief are important factors in determining the climate of India.
There are basically 6 factors affecting India's climate.
1) LATITUDE - Due to the curvature of the Earth, the amount of solar energy received is different according to the latitudes.
2) ALTITUDE - As we go higher, temperature generally decreases (From equator to poles) as the atmosphere becomes less dense.
3) PRESSURE AND WIND SYSTEM - They depend on the latitude and altitude of a place, thus influencing the rainfall patterns.
4) DISTANCE FROM SEA - The sea has a moderating effect on the climate. As distance from sea increases, this effect decreases and places experience extreme weather conditions (continentality).
5) OCEAN CURRENTS - They affect the climate of the coastal areas with the onshore winds.
6) RELIEF - High mountains act as barriers for cold/hot winds, may also cause precipitation if they are high enough and lie in the path of rain bearing winds. The leeward side of the mountains remains dry.
