Explanation: Mawsynram, a village in the East Khasi Hills district of Meghalaya, holds the record for the highest annual rainfall in the world. This village is located near Cherrapunji, another well-known place for high rainfall. The region's unique topography and location make it a hotspot for monsoon rains.
The Khasi Hills, where Mawsynram is situated, are part of the Eastern Himalayan range. The region's proximity to the Bay of Bengal and the prevailing monsoon winds play a significant role in the high rainfall. The monsoon winds, laden with moisture, are forced to rise over the hills, leading to the formation of clouds and heavy rainfall. This phenomenon is known as orographic precipitation, where the topography of the land forces air to rise, cool, and condense, resulting in precipitation.
Mawsynram receives an average annual rainfall of about 11,871 millimeters (467.4 inches), making it the wettest place on Earth. Cherrapunji, which is also in the same region, was previously recorded as the wettest place in the world, with an average annual rainfall of about 11,777 millimeters (463.7 inches). However, recent records have shown that Mawsynram surpasses Cherrapunji in terms of annual rainfall.
The high rainfall in this region is not only due to the monsoon but also due to the presence of cyclones and depressions that form over the Bay of Bengal. These weather systems bring additional moisture and contribute to the heavy rainfall in the region.
It is important to note that while Mawsynram and Cherrapunji are known for their high rainfall, the region also faces challenges such as landslides and soil erosion due to the heavy rains. The local communities have adapted to these conditions by developing unique architectural styles and agricultural practices that are resilient to the heavy rainfall.
In contrast, the other options listed—Jaisalmer, Drass, and Kargil—are located in regions that are generally dry and do not receive high rainfall. Jaisalmer is in the Thar Desert, known for its arid climate, while Drass and Kargil are in the high-altitude regions of Jammu and Kashmir, known for their cold and dry climate.
Understanding the geographical factors that contribute to high rainfall in Mawsynram and Cherrapunji is crucial for comprehending the unique climate patterns of the northeastern region of India. This knowledge is essential for students studying geography, climate science, and environmental studies.
