(a) Monsoon winds are generated due to uneven heating of land & water in different seasons. During summers, monsoon winds blow from sea to land & in winter they blow from land to the sea.
(b) The influence of monsoon winds is seen in summer season in the Indian subcontinent due to high temperature & low pressure in Thar desert region & Punjab plains.
(c) As these winds blow from sea to land the Indian subcontinent experiences monsoon (rainy) season.
(d) During winters, due to high pressure & low temperature in the Indian subcontinent & comparatively low pressure & high temperature in the Indian ocean winds blow from land to sea.
(e) This is the retreating monsoon season in the Indian subcontinent.
Thus the Indian subcontinent experiences monsoon & retreating monsoon season.
