| 摘 要： | 2002年10月21～22日青海高原东部地区发生近10年以来秋季最强的一次暴雪天气过程。利用Q矢量方法以及GMS-5红外云图、水汽云图和常规观测等资料，对强暴雪天气进行了天气动力学诊断分析。结果表明：Q矢量湿锋生函数、Q矢量散度场和水汽通量散度场与青海高原暴雪区有较好的对应关系，对青海高原的降雪预报有指示作用。

| Abstract: | The snow-storm in the eastern part of Qinghai Plateau during 21-22,October 2002 was the heaviest process in the last 10 autumns. Based on infrared imagery,vapor image and some conventional observation,the synoptic diagnostic analysis of the snow-storm is made. The results show that there is a good corresponding relationship between Q-vector moist frontolysis function,Q-vector divergence,vapor flux divergence and the snow-storm region of the Qinghai Plateau,and this has a good implication for the snowfall forecast in the Qinghai Plateau. |
