Monsoon Trough Brings Rain

Despite the arrival of the southwest monsoon in India, Delhi and several parts of North India have continued to experience intense heat. The India Meteorological Department (IMD) has now forecast significant rainfall as a monsoon trough stretching nearly 1,500 kilometres from the northern Bay of Bengal to Jammu and Kashmir has begun shifting southward. According to the IMD, widespread rainfall is likely across North India between July 1 and July 4.

A monsoon trough is a weather system formed by moisture-laden winds that creates a low-pressure zone, bringing widespread rainfall. For the past several days, the trough remained close to the Himalayan foothills, delaying rainfall over Delhi, Haryana and Rajasthan, where temperatures touched 43°C to 45°C. Meteorologists now say atmospheric conditions have become favourable, and the possible formation of a low-pressure area over the Bay of Bengal could further strengthen monsoon activity across North India.
