英文摘要	Snow depth plays an essential role in the water and energy balance of the land surface. It is of special importance in arid and semi-arid regions of Central Asia. Owing to the limited availability of field observations the spatial and temporal variations of snow depth are still poorly known. Using the Japanese 55-year (JRA-55) and the ERA - Interim reanalysis snow depth products we considered four global climate models (GCMs) applied in the Inter-Sectoral Impact Model Intercomparison Project (ISI-MIP) examining how they represent snow depth in Central Asia during the period 1986-2005 in terms of spatial and temporal characteristics. We also investigated changes of winter (January-March) snow depth in Central Asia, at 1.5 degrees C and 2 degrees C global warming levels. Finally the joint probabilistic behavior of winter temperature and precipitation at 1.5 degrees C and 2 degrees C global warming are investigated using the kernel density estimator (KDE). The result shows that the snow depth climatology of Central Asia is generally well simulated in both spatial pattern and temporal (inter-annual and inter-seasonal) pattern. All models approximately simulate the winter maximum and the summer minimum values of snow depth but lend to overestimate the amplitude during October-December. Only the trend in HadGEM2-ES matches fairly well to the JRA-55 reanalysis snow depth. When comparing the projections of spatial distribution of winter snow depth distinctive spatial pattern is noted at both 1.5 degrees C and 2 degrees C global warming levels when the snow depth is shown to increase in northeastern and to decrease in midwestern regions of Central Asia. According to the joint probability distributions of precipitation and temperature Central Asia will tend to experience a warmer and wetter winter at both 1.5 degrees C and 2 degrees C global warming levels which can be associated with an increase in snow depth in the northeastern regions.
