中文摘要：

天气研究的性能并且预报(WRF ) 在在东北中国上模仿季节的降雪的模型被检查。水平分辨率和物理 parameterization 计划的影响也被调查。结果显示 WRF 能相当复制温度和降水的主要特征。模仿了与观察作比较很好的降雪的空间、时间的分发。更高的决定模拟完成了更好的结果，并且 WRF 被发现比对流积云 parameterization 计划对陆地表面和微视物理学计划的选择更敏感。

英文摘要：

Performance of the Weather Research and Forecasting （WRF） model in simulating seasonal snowfall over Northeast China was examined. The influences of horizontal resolution and physics parameterization schemes were also investigated. The results indicate that WRF can reasonably reproduce the main features of temperature and precipitation. The simulated spatial and temporal distribution of snowfall compared well with observations. Higher resolution simulations achieved better results, and WRF was found to be more sensitive to the choice of land surface and microphysics scheme than convective cumulus parameterization scheme.
