摘要
本文根据桂林市气象局12UTC的T-lnP图计算得出的K指数与桂林两江机场2004-2013年2-4月观测资料中06-18UTC时段内所发生雷雨天气的相关关系进行统计分析。结果表明:桂林机场春季午后雷雨发生时,K指数>20℃的占比极高,达到91.7%。桂林机场春季午后K指数>39℃时对应的雷雨日数最多且雷雨发生概率为最高,达到50.0%;其次是K指数在37-39℃时雷雨发生概率为20.0%。
In this paper,the correlation between K index calculated from 12 UTC T-lnP chart of Guilin Meteorological Bureau and thunderstorm weather occurred during 06-18 UTC period in observation data of Guilin Liangjiang Airport from February 2004 to April 2013 is analyzed.The results show that when thunderstorms occur in spring afternoon at Guilin Airport,the proportion of K index>20 C is very high,reaching 91.7%.The number of thunderstorm days corresponding to K index>39 C in the spring afternoon of Guilin Airport is the largest and the probability of thunderstorm occurrence is the highest,reaching 50.0%.The next is the probability of thunderstorm occurrence when K index is 37-39 C.The probability of thunderstorm occurrence is 20.0%.
