Rainfall is an essential part of the hydrological cycle and is a major factor in sustaining life on Earth. India, being a tropical country, is highly dependent on rainfall for its agricultural activities and to meet its water needs. It is not surprising, then, that rainfall is an important topic of discussion in the country. In this article, we will explore why the rainfall in Northern India decreases in the east as compared to the west.
Rainfall in Northern India
Rainfall in India is highly seasonal, with most of the country receiving its annual rainfall during the monsoon season. The northern part of India is one of the most important regions in terms of rainfall, as it provides water for the major rivers of the country. The average annual rainfall in this region varies from 500 to 1500 mm.
East vs West
The northern part of India is divided into two parts: the east and the west. The east receives less rainfall than the west. This is because the monsoon winds that bring the rains to the region are blocked by the Himalayan mountains. The winds are forced to pass over the mountains, causing them to lose their moisture and thus reducing the amount of rainfall they bring. The western part of the region, on the other hand, is exposed to the monsoon winds and receives more rainfall.
Another factor that contributes to the difference in rainfall between the east and the west is the topography of the region. The eastern part of the region is generally lower in elevation than the west, and this makes it more prone to evaporation. As a result, the amount of rainfall received in the east is less than in the west.
In conclusion, the rainfall in Northern India is lesser in the east as compared to the west due to the blocking of the monsoon winds by the Himalayas and the lower elevation of the eastern part of the region. This difference in rainfall is an important factor to consider when planning agricultural activities in the region.
