Question

Why does Break in Monsoons occur?

Answer 1

1. Shift in the Monsoon Trough: The monsoon trough, which is a region of low pressure that drives the monsoon rains, may shift northward or weaken, leading to a reduction in rainfall.
2. Failure of Tropical Depressions: The tropical depressions or low-pressure systems that usually bring heavy rainfall may weaken or fail to form during the break, leading to dry conditions.
3. Atmospheric Changes: Sometimes, the low-pressure areas (L.P.) that bring rainfall may be replaced by high-pressure systems (H.P.), leading to clear skies and dry weather.
4. Wind Pattern Changes: Changes in the direction of winds or the weakening of southwest monsoon winds can also contribute to a temporary lull in rainfall.
