Rainfall is a critical component of the hydrological cycle, and its variation has significant implications for the environment. In northern India, rainfall decreases from east to west, resulting in significant regional differences in precipitation. This article explores the effects of this east-west rainfall variation and the reasons for its decrease in northern India.
Effects of East-West Rainfall Variation
The east-west variation in rainfall in northern India has many implications for the region. The most significant effect is the difference in water availability. Areas of northern India with higher rainfall receive more water, while areas with lower rainfall experience water scarcity and drought. This can have a major impact on the local economy, as well as the environment. Additionally, the east-west variation in rainfall can lead to regional differences in temperature and humidity, which can have an effect on air quality.
Reasons for Decrease in Northern India
The decrease in rainfall from east to west in northern India is largely due to the region’s geography. Northern India is located in the tropics, and is affected by the monsoon winds that blow from the south. These winds are blocked by the Himalayas, resulting in less precipitation in the western areas of the region. Additionally, the region’s topography plays a role in the east-west rainfall variation. Areas of higher elevation, such as the Himalayas, receive more precipitation, while areas of lower elevation, such as the Thar Desert, receive less.

Understanding the effects of this east-west rainfall variation is essential for effectively managing the region’s water resources.
