Which one of the following causes rainfall in the north-western parts of India during Winter Season ?
– Western Disturbances are low-pressure systems originating over the Mediterranean Sea. They travel eastward across Iran, Afghanistan, and Pakistan, bringing moisture which causes precipitation in the form of rain and snow over the Himalayas and the plains of north-western India during the winter months (generally from December to March).
– Cyclonic depression can cause rainfall, but the specific winter rain in NW India is linked to the characteristic movement of Western Disturbances.
– Retreating Monsoon affects the southern parts of India, particularly the Tamil Nadu coast, during the autumn/early winter months (October-November).
– South West Monsoon is the primary monsoon season in India, bringing rainfall from June to September to most parts of the country, but not the cause of winter precipitation in the northwest plains.
