摘要
利用2009—2013年广西预警信号发布通知单及评价表等资料,运用分类统计等方法,得出了近4年广西各类预警信号发布的时空分布特征、发布频次及发布准确率。资料表明:暴雨、雷电、高温预警信号是广西使用最频繁的3类灾害性天气预警信号,预警发布总数分布呈西少东多的态势,预警信号发布准确率较高,正确预警中提前预警所占的比重最大。针对预警信号面临的新形势,提出加强气象灾害预警信号发布的若干对策,以期进一步增强气象预警能力,提高气象预警水平。
The temporal and spatial distribution characteristics, the frequency of early warning release, and the accurate rate of meteorological disaster warnings in Guangxi are studied by using the warning notices issued in Guangxi from 2009 to 2012 and the evaluation forms, by means of classification and statistical methods. The results show that such three kinds of disaster weather warnings as heavy rain, lightning, high temperature are most frequently i than that in the eastern Guangxi. Th proportion of advance warnings is the early warning, some countermeasures meteorological warning. ssued. The total number of warnings in the western Guangxi is less e accuracy rate of the issued warnings is relatively high, and the biggest in correct warnings. Considering the new situation faced lay are given to further improve weather forecasting and the level of
