than commonly exists in nature. It appears that further observational information on the intensity of the various types of landscape-induced thermal circulations is needed in order to quantify these circulations. In the absence of sufficient observational data, which typically are obtained in a special field project, any indirect support from routine observations should be beneficial. One well-defined type of landscape variation is occasionally associated with snow cover. Snow cover is often

Near-surface temperature forecasts obtained from damped persistence of low temperatures from the previous winter and early February snow depth are used as a baseline to judge the performance of the CGCMs. We then relate the 2-m temperature to snow water equivalent (SWE) and snow cover to explain the physical basis of the model skill. 2.

discussed by DeWeaver and Nigam (2000) , is through the coupling between the zonal-mean flow and waves. Forcing of the interannual pattern of variability associated with the NAO (AO) mode has also been attributed to other factors such as natural and anthropogenic changes in atmospheric chemistry ( Kodera and Yamazaki 1994 ; Shindell et al. 1999 ; etc.). To date however, no firm conclusions have been reached. Recently it has been shown that September, October, and November (SON) Eurasian snow cover and
