云南省降雪特征分析

On the Characteristics of Snowfall in Yunnan Province

阐述了云南降雪形成的山地环境因子.同时运用统计方法对云南1980—2000年降雪的时间与地域空间的格局变化进行分析,初步把云南降雪区域划分为滇西北高山常年—长期降雪区、滇中—滇东北山原季节降雪区、滇西—滇东南山地少降雪区和滇南—滇西南无降雪区.

Taking Yunnan as an example, the paper illustrated the mountain environment elements in the formation of snowfall based on the information of environment, climate and weather, and climati-cally induced disease. Then the paper laid special stress on analyzing the spatial distribution and tem-poral variations of snowfall occurred during 1980s and 2000s using statistical methods. At last, a pre-liminary snowfall regionalization plan of the province was given. There are four zones in the regional-ization including the Western High Mountain Perennial and Longtime Snowfall Zone, the Eastern Mountain Plateau Seasonal Snowfall Zone, the Western and East-southern Mountain Little Snowfall Zone and the South and West-southern Non-snowfall Zone.
