Explanations:The climograph of Calcutta (Kolkata) is a graphical representation of the city's climate, showing the average temperature and precipitation over the course of a year. Understanding the climograph is essential for comprehending the seasonal patterns and weather conditions in the region.
Calcutta is located in the eastern part of India, and its climate is heavily influenced by the monsoon system. The monsoon season in South Asia typically occurs from June to September, bringing significant rainfall to the region. This heavy rainfall is a defining characteristic of the climograph of Calcutta, as it shows a distinct wet season during the monsoon months.
The monsoon season is crucial for agriculture and water supply in South Asia, but it also leads to seasonal flooding. The heavy rainfall during the monsoon can cause rivers to overflow, leading to flooding in low-lying areas. This is a common occurrence in many parts of South Asia, including Calcutta, and is a significant aspect of the region's climatic pattern.
It is important to note that the climograph of Calcutta does not show four distinct seasonal changes in weather. Instead, it shows a monsoon-influenced climate with a wet season during the monsoon months and a dry season during the rest of the year. The temperature in Calcutta remains relatively stable throughout the year, with minor variations between the wet and dry seasons.
Mountain barriers, such as the Himalayas, do not significantly affect the rainfall in Calcutta during the summer. The monsoon winds bring moisture from the Bay of Bengal, which is the primary source of rainfall for the region. Therefore, the climograph of Calcutta does not indicate a lack of rainfall due to mountain barriers.
In summary, the climograph of Calcutta shows that South Asia experiences seasonal flooding due to the heavy rainfall brought by the monsoon season. This is a key characteristic of the region's climate and is reflected in the climograph of Calcutta.
