| 摘 要： | 利用常规气象资料和FY-2气象卫星资料,从天气形势、能量场特征和卫星TBB演变特征分析2006年4月23日发生在新疆玛纳斯河流域的强降雹天气过程的成因。结果表明,降雹当日冰雹云生成前低层是高能舌,中高层低能中心和负能量平流中心位于其西—西北方。东北—西南向的强能量锋区是触发这次强降雹过程的重要条件之一。这次强降雹天气过程出现在强对流云团前沿TBB梯度大值区内,云顶温度值及其水平梯度是识别冰雹云的重要参量。

Atmospheric Energy Analysis on a Strong Hail Process of Springtime in Manas Drainage Area |
| |
| Abstract: | Based on the data of conventional observation and FY-2 TBB,analyzed the character of weather situation and energy field about a hail process occurred Manas River drainage area on Apr.23,2006.The results showed there was a tongue of high energy at the low level and a center of low energy at the mid and upper level while a negative energy advection center was located over its west and northwest before the process happened on hail cloud genesis.The temperature of cloud top and its horizontal gradient were important parameters for identification of hail cloud. |
