This paper presents the lightning activity, aerosol optical depth (AOD) and climatic parameters (Bowen ratio, relative humidity, rainfall, maximum surface temperature and maximum updraft speed) over wet (Northeast India—NEI) and dry (Northwest India—NWI) land surfaces in a comparative analysis. The analyses are performed on flash counts and weather data of 17 years (1998–2014) retrieved from the Tropical Rainfall Measuring Mission (TRMM) lightning imaging sensors (LIS) and the Moderate Resolution Imaging Spectroradiometer (MODIS), respectively. The first higher peak for flash counts during pre-monsoon (April–May) and second lower peak during September over wet NEI and dry NWI regions indicate the development of strong electrified storms during pre-monsoon and weakly electrified clouds during the withdrawal phase of the southwest summer monsoon. The monthly means of flash counts, Bowen ratio, maximum surface temperature, AOD and maximum updraft speed are higher by 27, 81, 16, 50 and 16%, respectively, for NWI than those of NEI. The relative humidity and rainfall are higher by 12% and 73% for NEI than those of NWI, respectively. The Pearson’s correlation coefficients of lightning activity with climatic parameters and AOD demonstrate the distinctive orographic lifting, moisture content and vertical wind shear in the upper troposphere in the regional climatic zone of dry NWI in comparison to that of wet NEI.

本文介绍了湿润（印度东北—NEI）和干旱（印度西北—NWI）土地上的闪电活动，气溶胶光学深度（AOD）和气候参数（Bowen比，相对湿度，降雨量，最高表面温度和最大上升速度）比较分析中的曲面。分别对分别从热带雨量测量任务（TRMM）闪电成像传感器（LIS）和中等分辨率成像光谱仪（MODIS）检索的17年（1998-2014）的闪光计数和天气数据进行了分析。在潮湿的NEI和干燥的NWI地区，季风前（4月至5月）的闪光计数的第一个较高峰值和9月期间的第二个较低的峰值指示在季风前期强的电气化风暴的发展和在退缩阶段的弱电化的云的发展。西南夏季风。与NEI相比，NWI的每月闪光次数平均值，Bowen比，最高表面温度，AOD和最大上升速度分别高27％，81％，16％，50％和16％。NEI的相对湿度和降雨量分别比NWI高12％和73％。皮尔逊闪电活动与气候参数和AOD的相关系数表明，与湿NEI相比，干NWI区域气候区对流层上部的地形抬升，水分含量和垂直风切变具有显着性。
