Northern India experiences a wide range of climatic conditions, with the western regions being the driest and the eastern regions being the wettest. Rainfall in Northern India decreases from east to west. This phenomenon is due to a number of factors, including the topography of the region, its proximity to the Bay of Bengal, and the influence of the monsoon.
Causes of Decreasing Rainfall in Northern India
The topography of Northern India is a major factor in the decreasing rainfall from east to west. The Himalayan Mountains act as a barrier to the moisture-laden winds that come from the Bay of Bengal, resulting in lower rainfall in the western regions. The monsoon winds also play an important role, as they tend to move from east to west and bring with them the moisture-laden air. This results in higher rainfall in the eastern regions and lower rainfall in the western regions.
Impact of Decreasing Rainfall
The decrease in rainfall from east to west in Northern India has a significant impact on the region’s climate and ecology. The lack of rainfall in the western regions leads to a decrease in soil moisture, resulting in reduced crop yields and lower agricultural production. This can have a serious impact on the livelihoods of people in the region, as they are dependent on the agricultural sector for their income. Additionally, the decrease in rainfall can also lead to an increase in water scarcity, as the lack of rainfall results in lower water levels in rivers and reservoirs. This can lead to serious water shortages, particularly in the dry season.
