Consider the following statements:1. Western Disturbances are called ...
Statement 1 is correct. Mawath refers to the winter rainfall in Rajasthan, caused by Western Disturbances during the months of December and January. These rains are very beneficial for the Rabi crops like wheat and mustard.
Statement 2 is correct. While the Arabian Sea Branch is more powerful than the Bay of Bengal Branch, it is the latter which provides rain to large parts of India, including Gangatic plains, North-East India, Odisha plains and Central India.
Arabian Sea branch gives copious rainfall on Western Coast, some parts of central India along Narmada and Tapi valley, parts of Gujarat. However, it gives almost no rainfall in Rajasthan as Aravallis are parallel to the branch.
Rajasthan, hence receives some amount of rainfall only from the Bay of Bengal Branch during the monsoon season.
The two branches meet and combine near Delhi to give rainfall over the rest of Northern India.
Statement 3 is incorrect. Konkan coast extends throughout the western coasts of Maharashtra, Goa and Karnataka.It is bounded by the Western Ghats mountain range (also known as Sahyadri) in the east, the Arabian Sea in the west. It receives rainfall mainly from the South-west monsoon.
It is the Coromandel coast which receives rainfall from the North-East or the retreating monsoon.
