概要	20-km non-hydrostatic regional climate model (NHRCM) were nested in the JRA-25 reanalysis to reproduce snow phenomena of the present climate around Japan during 1985-2004 winter (December to March). To verify the NHRCM, Monthly mean values for snow depth, surface air temperature, total precipitation, and snowfall derived from observations of the AMeDAS were used. The results were (1) surface air temperatures were simulated over Japan, with cold biases of about 1 deg. on the Pacific Ocean side of Tohoku district and warm biases of 1-2 deg. on the Japan Sea side, (2) generally underestimated monthly total precipitation, snowfall, and snow depth, and the regression coefficients of the modeled values against observed values were only 0.3, 0.3, and 0.4, respectively, (3) these biases decreased at elevations above 500 m, and (4) both modeled and observed surface air temperatures in winter were distributed bi-modally.
