Influence of freezing and thawing processes on diurnal temperature range in the Arctic

S. K. Saha, A. Rinke, K. Dethloff


The diurnal temperature range has been simulated for 15 years (1979-1993) by two versions of a regional climate model over circumpolar Arctic region. Both
models, one with simplified soil scheme and the other with more complex soil scheme, are able to capture the variability of observed diurnal temperature range quite realistically. Model with complex soil scheme is able to improve the simulation of monthly mean diurnal temperature range significantly during spring, summer and autumn. A sensitivity study without freezing and thawing of soil moisture underlies the importance of freezing and thawing process of soil moisture on the diurnal temperature range, particularly during spring and autumn. The connection between land-surface and the lower part of atmosphere becomes stronger when the surface air temperature within a day changes from negative to positive or vice versa. This study illustrates that the freezing and thawing processes of active layer is one of the key factors that influence diurnal temperature range in the Arctic.
