Study Notes
- South-west monsoon winds lower temperatures in India during the summer.
- This is most apparent during June, July, and August.
- These winds originate from a high pressure region in the Indian Ocean.
- They move towards low pressure regions in the heated parts of northern India.
- This results in heavy rainfall.
Western Disturbances
- Western disturbances are winds from the Mediterranean.
- They move towards India in the winter.
- They cause light showers in north-west India.
North-East Monsoon Winds
- North-east monsoon winds bring rainfall to the Tamil Nadu coast during winter.
- These winds gather moisture from the Bay of Bengal.
- They originate from high pressure areas of north India and move to the Indian Ocean.
- The Indian Ocean has low pressure.
Inter Tropical Convergence Zone
- The Inter Tropical Convergence Zone (ITCZ) is a convergence zone for the south-east and north-east trade winds.
- The ITCZ is a low pressure area that lies on the Equator (0°).
- During summer, the ITCZ shifts over Central India.
- This is caused by the apparent shift of the Sun over the Tropic of Cancer.
- This attracts the south-east.
- South-west winds strike the west coast of India.
- Western disturbances are cyclonic storms.
- These storms occur during the cold season in northwest India.
