Snow line is a line above which no vegetation grows on high altitude mountains

because of permanent snow cover. This snow line is higher for Eastern Himalayas

compared to that of Western Himalayas. What are the reasons?

Consider the following statements

1. Eastern Himalayas are near to the Equator.

2. Western Himalayas are more continental in their location thus has lesser maritime

influence.

3. Southwest monsoon winds have the moderating effect on the Western Himalayas.

Explanation:

Snowline is a function of altitude and latitude. Higher is the latitude and altitude lower is the
snowline. Eastern Himalaya’s altitude as well as latitudinal location is lower compared to
Western Himalayas. Due to higher altitude as well as latitude the temperature is much less
in the Western Himalaya and as a consequence the snowline in the Western Himalaya is at a
lower altitude than in the Eastern Himalaya. Southwest monsoon winds bring more rainfall
to Eastern Himalayas than compared to Western Himalayas. Thus monsoon winds can have
moderating effect on Eastern Himalayas and in turn increasing the altitude of snowline.
Thus 3rd statement is wrong.
