| 摘 要： | 应用昆仑山北部小时、分钟降水资料以及和田C波段多普勒天气雷达资料，分析近8年该区域短时强降水天气分型，对比分析对流云与混合云2型5类短时强降水的回波强度、顶高、垂直液态含水量等回波特征量值以及持续时间的差异。得出昆仑山北部短时强降水中，中亚低涡（槽）型环流形势和块状多单体回波最多，昆仑山北坡无超级单体回波。需高度关注3类天气分型下高空锋区、低层中尺度气旋、切变线和辐合线以及东风气流（急流）等高低空天气系统空间配置以及强度对短时强降水落区、强度的影响。

| Abstract: | Using hourly and minute precipitation data in northern Kunlun Mountain and Hetian C-band Doppler weather radar data, the weather classification of short-term heavy precipitation in this area in the past 8 years was analyzed, and the convective cloud and mixed cloud type 2 and 5 types of short-term heavy precipitation were compared and analyzed. The difference in echo characteristic value and duration such as echo intensity, ceiling height, and vertical liquid water content. It is concluded that in the short-term heavy rainfall in the northern part of Kunlun Mountain, the low vortex (trough) circulation pattern and massive multicell echoes in Central Asia are the most, and there is no supercell echo on the northern slope of Kunlun Mountain. High-altitude weather systems such as high-altitude frontal areas, low-level mesoscale cyclones, shear lines and convergence lines, and easterly wind currents (jets) under the three types of weather types need to be paid close attention to. influences. |
