Abstract: Snowcover play an import role in earth's ecosystem. In Apline and terrain with complex topography, the blowing snow have heavy impact on snow accumulation and ablation. The Mayitas region is world famous for suffering from blowing snow hazards, which is also without covering the meteorological observation. To solve the lack of observation, this study uses the date time of blowing snow occurrence that retrieved from news on Internet as the quasi observation. And the wind field and snowfall is reproduced by WRF model. Results show that when the daily snowfall is more than 1.03 mm/day and the mima of daily maximum wind speed is more than 8.84 m/s could be the practical criteria for forecasting the blowing snow events. And finer grades could improve the wind speed's spatial characteristics with the experience from field survey.
