摘要:

根據(jù)江蘇省46a來13個(gè)地面觀測(cè)站的雷暴日資料、4a的電力部門閃電定位資料以及2a的氣象部門閃電定位資料,分析研究了江蘇省雷電活動(dòng)的時(shí)空分布特點(diǎn).結(jié)果表明,江蘇省雷電總的地域分布趨勢(shì)是,南部比北部多,西部比東部多;丘陵低山地區(qū)多于大片的平原地區(qū),陸上大的水體附近也是多雷區(qū),而且江蘇省的雷電多發(fā)區(qū)與經(jīng)濟(jì)發(fā)達(dá)區(qū)大體重疊.這些地域應(yīng)是防雷的重點(diǎn)地區(qū).江蘇省的雷暴發(fā)生時(shí)間主要集中在3-9月,全省雷電多發(fā)時(shí)段在16-17時(shí),但地域間因地形地貌及雷暴源地的不同,各地日平均逐時(shí)分布的差異明顯.

Abstract:

An analytic study of the time-space distribution features of lightning activities has been completed on the basis of ground weather observation and the lightning location data. The results show there are more lightning activities in the southern regions than those in the northern regions; more lightning activities in the western regions than those in the eastern regions; more lightning activities in the hilly countries than those in the flatlands; more lightning activities in those in-land areas close to big water sources. Besides，the frequently-occurring regions of the lightning activities are roughly in coincidence with the economically developed regions of Jiangsu Province. All these regions should be the focal points to complete the lightning protection. The lightning storms in Jiangsu Province mostly happen in a period from March to September. And the lightning activities occur frequently in a period from 16:00 to 17:00. But, the daily mean hour-by-hour distribution of the lightning activities is clearly different in different regions because of their different terrains, landforms and their different lightning storm sources.
