Winds — Geography STD 11 Arts — Question

• Some Asiatic landmass cools faster in winter.
• So high pressure pockets develop here.
• At this time the nearer water mass is a little warmer, so low pressure pockets develop there.
• As a result, winds blow from landmass towards oceans.
• These winds blow over South and South-Asian countries from north-east direction, so these are called North-East Monsoon Winds.
• As these winds blow over from landmass, they contain less moisture and do not give much rain.

When some of their branches pass over the ocean, they hold moisture.

• December January, the North-East Monsoon winds shower most of the annual rains over Coromandel

Coast on the eastern sea coast of India and to northern parts of Sri Lanka.

• Rains caused by these monsoonal winds is irregular and uncertain.
• The rainy season starts earlier sometimes and ends also earlier.
• It starts late sometimes but ends earlier.
• Sometimes these monsoon winds cause very heavy rains or occasionally cause droughts.
• That is why the farmers of this region believe in fate.
• In India, monsoon winds are responsible for uncertainty of rainfall.
