Explanation: India's rainfall distribution is highly variable and influenced by several factors, including the monsoon winds, topography, and geographical location. The monsoon season, which typically occurs from June to September, brings significant rainfall to many parts of India, particularly to the regions located in the north and northeast.
Western Uttar Pradesh, Haryana, Punjab, and Eastern Rajasthan are regions that receive an annual rainfall between 50-100 cm. These areas are influenced by the monsoon winds, which bring moisture from the Bay of Bengal and the Arabian Sea. The monsoon winds are crucial for the agricultural activities in these regions, as they provide the necessary water for crops.
Western Rajasthan, on the other hand, is part of the Thar Desert and receives significantly less rainfall, typically less than 50 cm annually. This region is characterized by its arid climate and is not influenced as much by the monsoon winds. The rainfall in Western Rajasthan is often erratic and insufficient for agriculture without the use of irrigation systems.
Understanding the rainfall patterns in different regions of India is essential for planning agricultural activities, water resource management, and disaster preparedness. The monsoon plays a critical role in determining the rainfall distribution, and its variations can have significant impacts on the economy and livelihoods of the people in these regions.
In summary, the regions that receive annual rainfall between 50-100 cm are Western Uttar Pradesh, Haryana, Punjab, and Eastern Rajasthan. These regions are influenced by the monsoon winds, which bring significant rainfall during the monsoon season, supporting agricultural activities and water resources. Western Rajasthan, due to its arid climate, receives less than 50 cm of rainfall annually and is not included in this category.
