In most areas of northern hemisphere and alpine environment areas, snow melt lead to the maximum instantaneous flow rate and is an important part of annual discharge. The present study investigated the effect of snowmelt on the surface waters and ground waters in B...
[1] The ‘‘Advanced Regional Prediction System’’ forecast model is extended up to the stratopause and over the entire hemisphere to simulate gravity waves during 24 January 2005. With a 15-km horizontal resolution, the simulation produces dominant gravity wave features near Eastern Greenland that are associated mainly with orographic forcing by the Greenland terrain. The simulated wave temperatu...
