| 摘 要： | 结合兰州新一代天气雷达的使用情况,介绍了其物理量产品中垂直积分液态含水量(Verti-cally Integrated L iqu id W ater Content,)的理论计算模式,从雷达观测距离对VIL计算的影响、VIL理论模式中的反射率强度和探测高度对VIL计算的影响及VIL在强对流天气识别中受季节变化的影响3方面提出了思考,以期为今后应用VIL识别强对流天气提供参考。

| Abstract: | Based on the application of Lanzhou Doppler radar products,the theory pattern of vertically integrated liquid water content(VIL) which is one of radar physical quantity products was introduced in this article.Several issues was brought forward from the influence of radar detecting range and height,reflectivity intensity on the calculation of VIL,as well as VIL changed with season variation,so as to supply some references to distinguish severe convective weather based on VIL. |

| Keywords: | VIL theory pattern detecting range error discussion |
