摘要:
利用近5a来广西突发事件预警信息发布系统各级预警信号发布资料,对比分析2022年"龙舟水"过程预警信号分布特征。结果表明:(1)"龙舟水"过程期间,主要预警信号为雷电、暴雨,且暴雨预警以高级别红、橙色预警为主;(2)暴雨红橙色预警信号多发于午夜、凌晨及上午时段,中午及下午时段为发布低谷期;(3)暴雨预警信号平均生效时长为8.54h,较往年均值增长了2.9%,长时间生效暴雨预警信号(大于1d)数量较近5a均值增长了2.5倍;(4)暴雨预警信号在空间分布上表现为桂北多,沿海地区少。
Abstract:
Using the early warning signal release information at all levels of the Guangxi emergency warning information release system in the past five years, the distribution characteristics of the early warning signal in the process of dragon-boat precipitation in 2022 was compared and analyzed. The results show that:(1)The main warning signals are thunders and lightnings and rainstorms, and rainstorm warnings are mainly at high levels of red and orange warnings during the dragon-boat precipitation period;(2)The red and orange rainstorm warning signals are mostly issued at midnight, early morning and morning hours, while the noon and afternoon hours are low periods;(3)The average duration of rainstorm warning signals is 8.54h, showing an increase of 2.9% compared with the average value in previous years, and the number of long-time rainstorm warning signals (greater than 1 day) increased by 2.5 times compared with the average value in the past 5 years; (4)The spatial distribution of rainstorm warning signals is more frequent in northern Guangxi and less in coastal areas.
