地闪等级划分

1范围

本文件规定了地闪等级划分指标和方法。

本文件适用于地闪数据的分析统计及在雷电预警、风险区划中的应用。

2规范性引用文件

本文件没有规范性引用文件。

3术语和定义

下列术语和定义适用于本文件。

3.1

地闪cloud-to-groundlightning；CG

雷暴云与大地之间的放电现象。

[GB/T37047—2018,定义3.1.1]

3.2

雷电定位系统lightninglocationsystem；LLS

由多个雷电传感器组成的用于监测和定位其覆盖区域内雷电事件的探测网。

注：雷电定位系统又称闪电定位系统。

[GB/T37047—2018,定义3.1.10]

3.3

地闪强度cloud-to-groundflashIntensity

地闪放电的雷电流幅值。

注：单位为千安培（kA）。

3.4

地闪陡度steepnessoflightningcurrent

雷电流随时间上升的变化率。

注：单位为千安培每微秒（kA/μS）。

4地闪数据收集

主要使用雷电定位系统探测的雷电发生时间、地理位置、地闪强度、地闪陡度等资料。

5地闪等级划分

5.1划分依据

1

DB43/T2134—2021

根据地闪强度、地闪陡度综合划定。

5.2等级划分

按表1将地闪划分为4个等级。

表1地闪等级划分

等级名称地闪强度（kA）条件关系地闪陡度（kA/μS）

弱雷电[0，15)或＜5

中等雷电[15，25)且≥5

强雷电[25，50)且≥5

超强雷电≥50且≥5
