(i) The monsoon rain is unevenly distributed over India because most parts of India receive relief rainfall, therefore windward sides always receive more rainfall than the leeward side. Some places like Aravali and Coromandel coast lie parallel to south west monsoon winds, hence, are not able to obstruct these wind and receive very little rainfall.
(ii) Excessive cold in north India during winter season because north India is far from the sea and the equator. Hence, it experiences continental type of climate — cold winters and hot summers.
(iii) Most of the India remains dry during the North-East Monsoon season because north-east trade winds blow from land to sea and hence, do not carry moisture necessary for rainfall.
