i. These winds from the south-west bring rains to Indian subcontinent. During June to September, India gets rains. After this period these winds retreat.
ii. These winds blowing from the north pole region towards 60°N parallel cause cold wave conditions in extensive areas covering North America, Europe and Russia.
iii. Hilltops get heated quickly during the day. The air in this part becomes hot, light and starts ascending. Hence, a low pressure area forms in this region. At the same time the air at the foothills become cooler and also experiences high pressure. Air in that area blows towards low pressure.
