中文摘要: 用GMS-5水汽图像、红外云图、流场和云顶亮温TBB场,分析了1999年8月9日石家庄市区的强对流大暴雨。结果表明:(1)水汽图像中的较亮区域在对流层上部相对潮湿,水汽含量大,是强对流暴雨落区预报的参考依据;(2)水汽图像中较亮的湿区与θse高值区的重合,是强对流暴雨产生的重要物理因子。
中文关键词: 水汽图像,强对流,暴雨
Abstract:Based on the GMS-5 imagery and weather data,a severe convective storm on 9 August 1999 was analysed.The results show that (1)the brighter area in the moisture image is in the upper troposphere with higher moisture.It is one of the criteria in prediction of storm occurring area;(2)the coincidence of brighter area in moisture image with higher potential pseudo-equivalent temperature (θse) is an important physical factor in the occurence of a severe convective storm.
