Northern India experiences a decrease in rainfall as one moves from east to west. This phenomenon has been observed for many years and is caused by several factors. This article will discuss the reasons behind the eastward decline in rainfall and its impact on the region.
Eastward Rainfall Decline
Northern India is known to receive most of its rainfall from the monsoon season. During this season, the rains come more heavily from the east than from the west. The amount of rainfall decreases from east to west in a gradual manner. This phenomenon is seen in most parts of the region, with the exception of the Himalayan foothills, which experience a higher amount of rainfall from the west than from the east.
Causes of Decrease
The decrease in rainfall from east to west in Northern India can be attributed to several factors. The most prominent of these is the presence of the Himalayas. The Himalayas act as a barrier to the moisture laden monsoon winds, resulting in a decrease in rainfall as one moves further west. Another factor is the presence of the Thar Desert in the western part of the region. The desert acts as a barrier to the monsoon winds, resulting in a decrease in rainfall in the western part of the region. In addition, the presence of the Indus River in the western part of the region results in the moisture laden monsoon winds being diverted towards the east, resulting in a decrease in rainfall in the western part of the region.
The decrease in rainfall from east to west in Northern India has a significant impact on the region. The lack of rainfall in the western part of the region has resulted in a decrease in agricultural production, leading to a decrease in food security and economic growth. It is thus important to understand the factors behind the eastward decline in rainfall in order to develop strategies to mitigate its effects.
