What is a break monsoon phase?
"If the monsoon trough shifts close to the foothills of the Himalayas and remains there for two-three consecutive days, we call it a break monsoon phase," he said.
During the monsoon season, there are spells when the trough shifts closer to foothills of the Himalayas, leading to a sharp decline in rainfall over most parts of India. This is called a "break monsoon" phase.
Rainfall
In July, the monsoon had entered the first break phase
However, rainfall increases along the foothills of the Himalayas, northeast India, and parts of the southern peninsula.
In July, the monsoon had entered the first break phase even before reaching most parts of northwest India, including Delhi. The national capital and adjoining areas in northwest India entered a "break monsoon" phase again on August 10 that continued up to August 19.
