Parameterization Experiment on the Effect of Temperature on Snow Albedo and Snow Depth

B. Ahmad, S. Haider


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.
