贵阳机场夏季一次强对流天气分析

A Strong Convective Weather Analysis at Guiyang Airport in Summer

本文利用常规气象资料等对贵阳龙洞堡机场夏季一次强对流天气过程进行诊断分析。结果表明:此次强对流天气过程主要影响系统为高空槽、低层切变线及地面冷锋;低层暖湿平流的输送有利于强对流发生前不稳定层结的建立;中低层辐合,高层辐散的结构,使上升运动进一步加强,有利于对流天气的发生发展;大量的不稳定能量、充足的水汽和强烈的上升运动为强对流的发生提供了良好的条件。

In this paper, conventional meteorological data were used to diagnose and analyze the summer strong convective weather process of Guiyang Longdongbao Airport. The results show that the main influences of this strong convective weather process are high-altitude trough, low-level shear line and ground cold front. The transport of warm and humid advection in the lower layer is conducive to the establishment of unstable layers before the occurrence of strong convection. The structure of middle and low layer convergence and high layer radiation further strengthens the upward movement, which is conducive to the occurrence and development of convective weather. A large amount of unstable energy, sufficient water vapor and strong upward movement provide good conditions for the occurrence of strong convection.
