Both Statement 1 and Statement 2 are correct regarding breaks in the South-West Monsoon.
– Statement 1: Breaks in the monsoon in Northern India occur when the monsoon trough shifts towards the foothills of the Himalayas or is less active. This results in a decrease or cessation of rainfall over the plains, as the rain-bearing storms are no longer frequent along the typical position of the trough.
– Statement 2: On the West Coast, heavy rainfall is caused by the moist monsoon winds striking the Western Ghats. If the winds blow parallel to the coast, instead of perpendicular to the Western Ghats, the orographic lifting is significantly reduced, leading to a dry spell despite the winds potentially carrying moisture.
Breaks in the monsoon are periods during the monsoon season (June-September) when there is a significant reduction or cessation of rainfall over major parts of the country for several days. These breaks have different causes depending on the region. In the Ganga plains, it is often due to the shifting of the monsoon trough. On the West Coast, it is related to the offshore movement of the monsoon trough or changes in wind direction.
