What is Zero Balancing?

Snow line --- the lower limit of the hottest month's snow-covered area in a few years with little climate change, that is, an equilibrium line where the annual snowfall and the annual melting amount are equal. The snowfall above the snow line is greater than the annual melting amount. Snowfall accumulates year by year, forming perennial snow (or 10,000-year snow), which then becomes grain snow and glacier ice, which develops glaciers. The snow line is a climate marker. Its distribution height is mainly determined by temperature, precipitation and topographical conditions. The decrease in altitude from low latitudes to high latitudes reflects the influence of temperature.

The position of the snow line in one place is not fixed. Seasonal changes can cause snow lines to rise and fall:

Factors Affecting the Distribution of Snowline Heights

The altitude of the snow line in the Qinghai-Tibet Plateau varies greatly, and generally increases from the edge to the inside and from the southeast to the northwest. The snow line on the southeastern edge of the Qinghai-Tibet Plateau is located at an altitude of 4500 to 5000 meters. To the interior of the plateau, the snow lines such as the northern wing of the Central Himalayas and Gangdise Mountains are 5800 to 6000 meters above sea level. At an altitude of 6,200 meters, it is the highest snow line in the northern hemisphere.
