Explanations:The summer monsoon in India is a significant weather phenomenon that brings heavy rainfall to many parts of the country. However, the distribution of rainfall is not uniform across the entire subcontinent. Certain regions, particularly in the northeastern part of India, receive exceptionally high amounts of rainfall due to their unique geographical features and the influence of the monsoon winds.
Cherrapunji and Mawsynram, located in the state of Meghalaya, are renowned for receiving the highest rainfall in the world. This is primarily due to their location in the Khasi Hills, which are part of the Eastern Himalayan range. The Khasi Hills act as a barrier to the monsoon winds, causing them to rise and cool, leading to the formation of clouds and heavy rainfall. The monsoon winds, which originate from the Bay of Bengal, are forced to rise over these hills, resulting in orographic precipitation. This process is responsible for the exceptionally high rainfall in these areas, with Cherrapunji and Mawsynram often recording annual rainfall totals exceeding 11,000 mm.
Other regions mentioned in the options, such as Mumbai, Trivandrum, Goa, Agra, Delhi, Jaipur, Kolkata, Patna, and Bhuvaneshwar, also experience significant rainfall during the monsoon season. However, they do not receive the same level of precipitation as Cherrapunji and Mawsynram. Mumbai and Trivandrum, for example, are influenced by both the southwest and northeast monsoons, but their rainfall totals are significantly lower than those in Meghalaya. Similarly, cities like Agra, Delhi, and Jaipur, located in the northern part of India, experience a dry climate with occasional rainfall during the monsoon season, but they are not significantly affected by the heavy monsoon winds.
Understanding the geographical and climatic factors that influence rainfall patterns is crucial for comprehending the distribution of precipitation in India. The unique topography of the Khasi Hills and the influence of the monsoon winds make Cherrapunji and Mawsynram the places that experience the maximum rainfall during the summer monsoon.
