| 摘 要： | 利用祁连野外试验站观测资料,引入客观反映高空大气云和降水的表示方法,分析了祁连山区降水的大气特征。结果表明,高层冷云和低层暖云是祁连山区形成降水的主要云系,高层冷云由天气尺度系统决定,而低层暖云则由地形阻挡和加热等作用形成。在不同的天气系统下,地形对降水的作用不同。在西南气流影响下易形成谷风环流,从而增强降水;在西北风...

| Abstract: | Using the observated data of Qilian field experiment station and the introduction method of an objective reflection of upper atmospheric cloud and precipitation,the atmospheric characteristic of precipitation in the Qilian mountain is analyzed.The result shows that the cold cloud in upper level and warm cloud in lower level are to form main cloud systems of precipitation in the Qilian mountain,and the cold cloud in upper level depends on the weather system scale,but the warm cloud in lower level is formed b... |
