摘要
利用阿勒泰地区 6个气象台站的观测资料和常规天气图资料，分析了 2000年冬季降雪集中期和主要大-暴雪过程发生时的天气形势特点，归纳起来有以下特点：（ 1）欧洲中高纬度高压脊形势稳定；（ 2）长时间受极涡底部强锋区控制；（ 3）南支系统活跃，暖湿气流向北输送明显；（ 4）地形作用。
The weather situation of main snowfall period and heavy snow in 2000 are analyzed with routine weather map and daily data from six stations in Aletai region. The continuous heavy snow can attribute to the following:(1)a steady pressure ridge at the middle-high latitude in Europe.(2)control from strong frontal zone under polar vortex for a long time.(3)an active southern system transporting strongly wet and warm vapor northward.(4)topographic function.
