 What is snowline? 

Snow line, the lower geographical constraint of long-lasting snow cover. The snow line is an unpredictable line situated along the ground surface where the collection of snowfall approaches removal (softening and dissipation). This line differs significantly in height and relies upon a few impacts. On windward inclines and those confronting the evening sun, the snow line might be just about as much as a kilometer (the greater part a mile) higher than on inverse slants. Over bigger regions, summer temperatures and the measure of snowfall decide the situation of the snow line. Where temperatures are low, as close to the posts, the snow line is very low in height; where temperatures are high, as close to the Equator, the snow line is exceptionally high. Normal elevations of the snow line assumed control over huge regions can be utilized to determine a climatic snow line, which rises or falls in height because of overall climatic change. During cold periods, the climatic snow line was from 600 to 1,200 m (2,000 to 4,000 feet) lower than as of now.  

What is permanent snowline? 

 

The elevation above which or the scope past which snow doesn't dissolve in any event, during summer is normally called the extremely durable snow line. Components that influence the area of the snow line are winning climate conditions, especially strong precipitation and temperature.

When does a snowline move?

Snowline is the sea level on a mountain where it remains snow covered throughout the summer temperature. The location of snowline depends upon the height of the sun, latitude, winds, temperature and moisture. 

Then snowline on the same mountain range may change from year to year due to changes in the climate. The snow line is 5000 m above the sea level in the tropics, 2700 m in the Alps, 600 m in the Greenland and at the sea level near the Poles. The high elevations of a mountain is much colder than the lower points. The snow which falls on the higher regions never thaw because it is so cold. In the summer, the warm climate begins to melt some of the snow. This causes the snowline to move up the mountain. 

As the summer months pass by and the winter months return, the snowline moves further moves down the mountain once again. 

In the colder regions, the snow line is close to the ground level, but the air is warmer, the snow line is closer to the Equator. 

              

BITS OF FACT 

The climatic snow line in the Himalayas, which reside around 30 Degree North latitude, is approximately 4800 - 6000 m.

The Antarctic Is buried i over 4000m of snow. In March 1911, Tamaric in California, was buried in 11,460 mm of snow.
