India should have been an arid land,but it is not so. why?
India is not an arid land as the pressure and wind systems over India is quite unique. During winter , there is a high pressure area north of the himalayas. Cold dry winds blow from this region to the low pressure areas over the oceans to the south. In summer , a low pressure area develops over interior asia as well as over northwestern India. This causes a complete reversal of the direction of the winds during summer.
