2 and 3 only

1 only

1 and 3 only

Explanation:

Statement 1 is incorrect: Subtropical westerly jet stream blow south of the Himalayas, all through the year except in summer. Supplementary notes: Circulation over India

The Subtropical westerly jet streams are located approximately over 27°-30° north latitude. Over India, these jet streams blow south of the Himalayas, all through the year except in summer.

The western cyclonic disturbances experienced in the north and northwestern parts of the country are brought in by this westerly fl ow. In summer, the subtropical westerly jet stream moves north of the Himalayas with the apparent movement of the sun.

An easterly jet stream, called the subtropical easterly jet stream blows over peninsular India, approximately over 14°N during the summer months.

Tropical cyclones occur during the southwest monsoon, as well as, in October-November, and are part of the easterly flow. These disturbances affect the coastal regions of the country.
