摘要
研究热带气旋影响下广东省深圳地区的闪电特征及规律。利用2012—2019年西北太平洋热带气旋历史数据,筛选出2012—2019年距离深圳市国家气象基本站1000 km内的热带气旋,按热带气旋强度等级进行分组。并利用同时期深圳地区闪电、温度观测数据,研究不同等级热带气旋在不同距离、方位角情况下,深圳地区的闪电特征。发现热带气旋影响下深圳地区闪电年际差异很大,一年中7月和8月深圳地区闪电活动最活跃。热带气旋对深圳地区闪电活动影响大的距离大多为400 km以外,即深圳处于热带气旋的外围雨带。总体上在台风季,TD、TS、STS较易引发深圳地区的闪电,尤其是当TS位于福建地区,距离深圳400~600 km时,极易给深圳地区带来闪电影响。研究结果可为深圳地区的防台减灾工作提供科技参考。
This paper studied the characteristics and patterns of lightning in Shenzhen under the influence of tropical cyclones.Based on the historical data of tropical cyclones(TCs)in the Northwest Pacific Ocean from 2012 to 2019,the TCs within 1000 km to the Shenzhen Station were screened out and grouped according to their intensity.Moreover,using the lightning and temperature observational data in Shenzhen during the same period,the present study analyzed the characteristics of lightning induced by TCs with different intensity at various distances and azimuths in Shenzhen.It is found that the inter-annual variation of lightning in Shenzhen under the influence of TCs is very large,and the lightning activity in Shenzhen is the most active in July and August in a year.Most of the distances where TCs have a great impact on lightning activities in Shenzhen are beyond 400 km,indicating that Shenzhen is in the outer rainband of TCs.Generally,during typhoon season,tropical depression,tropical storm,and super tropical storm are more likely to cause lightning in Shenzhen,especially when the tropical storm is over Fujian Province,400~600 km away from Shenzhen.This article can provide scientific and technological reference for TCs disasters prevention and mitigation in Shenzhen.
