Explanation: Kolkata, the capital city of West Bengal, has a tropical wet and dry climate, which is characterized by distinct wet and dry seasons. The climate of Kolkata is influenced by the monsoon winds, which bring significant rainfall to the region during the monsoon season.
The monsoon season in Kolkata typically lasts from June to September. During this period, the city experiences heavy rainfall, high humidity, and frequent thunderstorms. The monsoon is crucial for agriculture in the region and plays a significant role in the overall water supply. However, the monsoon season is relatively short compared to the rest of the year.
Outside the monsoon season, Kolkata experiences a dry climate. The dry season can be further divided into two parts: the pre-monsoon season (March to May) and the post-monsoon season (October to February). During the pre-monsoon season, the city experiences high temperatures and low humidity, often leading to hot and dry conditions. The post-monsoon season, on the other hand, is characterized by cooler temperatures and low humidity, making it a pleasant time to visit the city.
The dry season in Kolkata is marked by low rainfall and high evaporation rates, which contribute to the dry conditions. The city's location near the Bay of Bengal and its proximity to the Himalayas also influence its climate, with the Himalayas acting as a barrier to the cold winds from the north and the Bay of Bengal providing moisture during the monsoon.
Understanding the climate of Kolkata is essential for planning various activities, including tourism, agriculture, and urban planning. The distinct wet and dry seasons require different strategies for water management, infrastructure development, and public health measures. For instance, during the monsoon season, there is a need for effective drainage systems to prevent flooding, while during the dry season, water conservation measures are crucial.
In conclusion, Kolkata remains predominantly dry throughout the year, with the exception of the monsoon months from June to September. This understanding of the city's climate is vital for anyone studying or living in West Bengal, as it impacts daily life, economic activities, and environmental management.
