| 摘 要： | 研究气象预警信号发布的时空特征与发布原则，对监测极端灾害性天气和发布预警信号有一定的指示意义.对湖北省2016—2019年期间发布的气象预警信号运用分类统计法按信号类别、等级、发布时间、发布区域进行统计分析，发现暴雨、大风、雷电、大雾、高温为主要的预警信号，预警落区主要分布在鄂东南、鄂西南，预警发生时间主要集中在夏季的7—8月.在此基础上，提出了湖北省气象预警信号的发布原则.

| Abstract: | A study into the space-time characteristics of meteorological early warning signalshave significance to extreme weather events monitoring and climatic disaster emergency management.The meteorological early warning signalsreleased by Hubei province during the period of 2016-2019 were statistically analyzed in classification of signal category,disastergrade,releasing date,and covered area.It is found that torrential rain,strong wind,thunder & lightning,heavy fog,and heat wave were listed as the main warning events,and mainly targeted at southeast and southwest of Hubei during July-August.The principles for releasing meteorological early warning signals are summarized for Hubei province. |
