Explanation: Shillong, the capital city of Meghalaya, is renowned for its exceptionally high rainfall, making it one of the rainiest places in the world. This characteristic is primarily due to its geographical location and the influence of the monsoon winds.
Meghalaya, which means "abode of clouds" in Sanskrit, is situated in the northeastern part of India. The region is characterized by its hilly terrain, which plays a crucial role in the precipitation patterns. During the monsoon season, which typically occurs from June to September, the prevailing winds from the Bay of Bengal are forced to rise over the hills of Meghalaya. As these moist winds ascend, they cool and condense, leading to heavy rainfall.
The most notable area for rainfall in Meghalaya is Mawsynram, a village near Shillong, which holds the record for the highest average annual rainfall in the world, with an average of over 11,000 mm. Shillong itself, while not the absolute highest, still receives an average annual rainfall of around 2,500 mm, which is significantly higher than other major cities in India.
In contrast, other cities like Mumbai, Chennai, and Kolkata, while they do experience substantial rainfall, particularly during the monsoon season, do not match the rainfall levels of Shillong. Mumbai, for instance, has an average annual rainfall of around 2,167 mm, Chennai around 1,300 mm, and Kolkata around 1,582 mm. These figures are considerably lower than those recorded in Shillong and the surrounding areas of Meghalaya.
Understanding the geographical and climatic factors that contribute to the high rainfall in Shillong is essential for comprehending the unique weather patterns in this region. The combination of its location, the influence of the monsoon winds, and the hilly terrain all contribute to making Shillong one of the rainiest stations in India and the world.
