| 摘 要： | 利用卫星云图、雷达探测和自动气象站记录等非常规观测资料，分析了2008年7月6日20时～7日20时形成于广西中北部的一条南北向暴雨带的降雨性质及成因，发现暴雨带北段主要是高空低槽前暖湿气流受整层抬升而形成深厚的层状云而产生强降雨，降雨性质属于间歇性降雨。虽然层状云间歇性降雨强度不大，但由于云层深厚而稳定，降雨时间长，累积降雨量大，形成了环江县、河池市等地的桂北暴雨区；在低槽底部，由于存在低层辐合区，槽前处于强位势不稳定。低槽过境时，槽后冷平流触发强对流运动，产生强阵性降雨，形成了以上林县为中心的暴雨带南段大暴雨区。 |

| Abstract: | Using the observatory data such as the satellite images,radar data and AWS records,the nature and the causes of a north-south orientation rain belt formed from 6 July to 7 July 2008 in mid and north Guangxi were analyzed.It shows that the northern section of the main rain belt results from the whole floor warm and humid air uplifting before high altitude trough and the deep layer stratiform clouds forming.The rainfall areas of Huanjiang County,Hechi City and other places in Northern Guangxi were created by ... |
