| Abstract: | In this paper, a few factors affecting the foehn of the east slope of Da-xinganling mountainchain in Northeast China in January are discussed by using the two-dimensional atmospheric meso-scale numerical model. The results show. ( 1 ) The leading topographic factor resulting in Daxinganling foehn is the east steep slope of Daxinganling mountainchain. The eastern gentle slope further promotes the development of .Daxinganling foehn. And the small-scale redges can be niglected. (2) The large-scale background conditions are essential for Daxinganling foehn forming. The Daxinganling foehn can not occur when the scorer number (N/U) of the largescale background field is too great or too small. |
