摘要
利用自动站观测资料、高空探测资料、卫星云图及雷达回波产品等对2020年8月27—31日米易县连续性降雨天气进行分析。结果得出:高原南下冷空气与暖湿气流在降雨区上空交汇,触发不稳定能量,西南急流不断向降雨区输送水汽,高低空配置形成有利动力条件,雷达回波、卫星云图等产品很好地诠释了降雨天气发展过程。累计降雨量预报能力需提高,同时,预警信息发布时间提前量有待提升。
Using data observed by automatic station,high detection data,satellite cloud images and radar echo products on August 27,2020-31 miyi continuous rainfall weather is analyzed,the results concluded that plateau cold air and warm moist air flow over the rainfall area,trigger instability energy,southwest jet constantly sending water to rainfall area,high and low empty configuration form favorable dynamic conditions,radar echo,satellite cloud picture products such as interpretation of well rain weather development process.The forecast ability of accumulated rainfall needs to be improved,and the advance of the release time of early warning information needs to be improved.
