地閃等級(jí)劃分

1范圍

本文件規(guī)定了地閃等級(jí)劃分指標(biāo)和方法。

本文件適用于地閃數(shù)據(jù)的分析統(tǒng)計(jì)及在雷電預(yù)警、風(fēng)險(xiǎn)區(qū)劃中的應(yīng)用。

2規(guī)范性引用文件

本文件沒有規(guī)范性引用文件。

3術(shù)語和定義

下列術(shù)語和定義適用于本文件。

3.1

地閃cloud-to-groundlightning；CG

雷暴云與大地之間的放電現(xiàn)象。

[GB/T37047—2018,定義3.1.1]

3.2

雷電定位系統(tǒng)lightninglocationsystem；LLS

由多個(gè)雷電傳感器組成的用于監(jiān)測和定位其覆蓋區(qū)域內(nèi)雷電事件的探測網(wǎng)。

注：雷電定位系統(tǒng)又稱閃電定位系統(tǒng)。

[GB/T37047—2018,定義3.1.10]

3.3

地閃強(qiáng)度cloud-to-groundflashIntensity

地閃放電的雷電流幅值。

注：單位為千安培（kA）。

3.4

地閃陡度steepnessoflightningcurrent

雷電流隨時(shí)間上升的變化率。

注：單位為千安培每微秒（kA/μS）。

4地閃數(shù)據(jù)收集

主要使用雷電定位系統(tǒng)探測的雷電發(fā)生時(shí)間、地理位置、地閃強(qiáng)度、地閃陡度等資料。

5地閃等級(jí)劃分

5.1劃分依據(jù)

1

DB43/T2134—2021

根據(jù)地閃強(qiáng)度、地閃陡度綜合劃定。

5.2等級(jí)劃分

按表1將地閃劃分為4個(gè)等級(jí)。

表1地閃等級(jí)劃分

等級(jí)名稱地閃強(qiáng)度（kA）條件關(guān)系地閃陡度（kA/μS）

弱雷電[0，15)或＜5

中等雷電[15，25)且≥5

強(qiáng)雷電[25，50)且≥5

超強(qiáng)雷電≥50且≥5
