摘要
利用2006—2015年广河国家气象观测站雷暴观测资料,挑选出了208个雷暴记录。根据雷暴发生个例,逐个查看2006—2015年5—9月MICAPS 8:00、20:00 500 h Pa高度场,将雷暴过程进行划分,得到了广河县雷暴过程的主要环流形势为槽后西北气流型、横槽型、槽过境型、低涡后部型。其中,最有利于广河县雷暴发生的天气型是槽后西北气流型或横槽型,其次是槽过境型。
By using the observation data of Guanghe National Meteorological Station during 2006-2015,208 thunderstorm cases were selected. According to the thunderstorm cases,the maps of MICAPS from May to September during 2006-2015 at 8：00 and 20：00 on 500 hPa height field were researched, the main thunderstorm circulation situation types in Guanghe County were northwest flow type, horizontal groove type, slot passage type and vortex type. The most advantage weather type of thunderstorm in Guanghe County was northwest flow type or horizontal groove type,follwed by slot passage type.
