Write down the characteristics of the climate of India.
Answers
Explanation:
The climate of India is characterised by the complete reversal of the wind system with the change of seasons. During the winter season, the winds generally blow from northeast to southwest (land to sea), while in summer season the winds blow from southwest to northeast (sea to land).
Explanation:
The climate of India is described as the ‘monsoon’ type because there is a seasonal reversal of wind system. During summer, winds blow from sea to land and during winters wind blow from land to sea.
The following factors factors explain monsoon type of climate in India:
Differential Heating and Cooling of Land and Water
a. Due to this lower pressure is found on the landmass.
b. High pressure is found on the water bodies/seas and oceans around India.
Shift in the position of Inter Tropical Convergence Zone (ITCZ)
a. Inter Tropical Convergence Zone is the equatorial trough (lower pressure area).
b. During summer it shifts its position to the Ganga plain, and is also known as monsoon trough, during the monsoon season.
Presence of High Pressure Area, East of Madagascar
a. The intensity and position of this high pressure area affects the Indian monsoon.
Intensely Heated Tibetan Plateau
a. Tibetan plateau gets intensely heated during summer.
b. It results in the strong vertical currents.
Westerly Jet Stream and Tropical Easterly Jet Stream
a. Westerly Jet stream moves to the north of the Himalayas.
Southern Oscillation
a. Changes in the pressure conditions over the southern oceans also affect monsoons. Normally when the tropical Eastern south Pacific Ocean experiences high pressure, the tropical Eastern south Indian Ocean experiences low pressure.
