Abstract
Dependence of snow albedo on temperature and its effect on surface temperature and snow depth has been investigated in this paper. A Global Circulation Model (PLASIM) has been simulated two times – once for a control run (without changing the dependence of snow albedo on temperature) and then for a modified run (with changes done in the dependence of snow albedo on temperature) on T21 grid resolution for a period of 20 years (1992-2011). Results reveal that the surface albedo, surface temperature and snow depth are all dependent upon each other. A negative incline in snow albedo is observed in the northern part of China where it goes below -0.04 in case of modified run. A positive incline of 0.04 and 0.04 - 0.05 has also been observed over the Himalayas and Tibetan plateau respectively for modified run. The modified run is colder than the control run (difference of -1.5 K) for the latitudes 60°N90°N and North-west Canada. Snow depth has significantly changed in the Greenland where it has been increased to a limit of 0.6 meters in the southwest and decreased to 0.2 meters in the northeast for modified run.
