“…The fraction of lightning strokes to the total northern hemisphere also increased significantly during 2010-2019 as derived from WWLLN. The distribution of lightning over the TP is closely coherent with meteorological factors which determine the initiation and intensification of the convection (Li et al, 2020;Toumi & Qie, 2004). Previous studies suggested that the regional climates of different TP areas are dominated by different climate systems (e.g., Xu et al, 2021;Yao et al, 2012).…”

“…Because of its unique thermodynamic forcing, the TP is an area with active convection systems which are significantly more frequent than that of the adjacent areas at the same latitude belt (Ye & Gao, 1979). As a product of convective systems, lightning activity is frequent over the TP from May to October (Li et al., 2020; Qie et al., 2003; Zheng & Zhang, 2021). People are often at risk of being struck by lightning when they travel, graze, or collect Cordyceps in open areas of the Plateau.…”

As a long-distance discharge phenomenon in nature, lightning not only poses serious risks to human beings but causes wildfires as well, which in turn affect the evolution of species and ecosystems (He et al., 2022;Hessilt et al., 2022). Lightning is the only natural source of nitrogen oxides (NOx) in the troposphere which regulates the oxidation ability in the upper troposphere and modulates tropospheric chemistry (Brune et al., 2021;Mao et al., 2021).Lightning activity shows large spatial heterogeneity on the globe with several lightning chimney regions around the equator (

This study investigates the relationship between transient luminous events (TLEs) and lightning strokes, and the characteristics of TLE‐producing thunderstorms over the Tibetan Plateau (TP), and compares them to those over the Yangtze‐River Delta (YRD) and East China Sea (ECS) where at the same latitude during 2005–2015. The data were collected using the Imager of Sprites and Upper Atmospheric Lightning (ISUAL) and the World Wide Lightning Location Network (WWLLN) observations. Elves, sprites and halo (abbreviated as ESHs) were dominantly detected over the southeastern TP (∼88%), mostly in August and September (∼81%). Different from the southeastern TP, the detected sprites and sprite‐to‐lightning stroke ratios over the YRD were larger in spring than those in summer and autumn. Halos were frequently observed in August over all study regions. Blue jets were only detected over the YRD. The density of TLEs over the southeastern TP was three times smaller than those over the YRD and ECS, while the density of elves over the southeastern TP was slightly larger than that over the YRD. The average energy of TLE‐related lightning strokes based on WWLLN was found to be larger over the southeastern TP compared to the YRD and ECS. The ESH‐producing clouds over the southeastern TP had a larger scale with a lower lightning frequency than those over the YRD.

“…It may lead to power system faults, cause wildfires, and even threaten life safety (Krause et al, 2014;Veraverbeke et al, 2017). In order to reduce the harm of lightning activities and further understand them for lightning monitoring and forecasting, the characteristics of lightning activities under different climatic factors are studied, such as temperature (Price and Asfur, 2006), precipitation (Zheng et al, 2016), aerosol (Tan et al, 2016;Shi et al, 2020), convective available potential energy (CAPE) (Qie et al, 2003;Pawar et al, 2012), and sensible heat flux (Qie et al, 2004;Li et al, 2020). Because the lightning activity occurs with complex physical mechanisms that are closely related to these meteorological factors.…”

“…The lightning activities produced there is closely related to the plateau thermodynamics (Qie et al, 2004). The charge structure of the thunderstorm cloud and the characteristics of lightning activities are also distinct from others (Li et al, 2020). Possibly affected by the Tibetan Plateau (Yu et al, 2007;Zhang et al, 2014), the Sichuan Basin on the east of it is the only high lightning density center in western China (Yang et al, 2015).…”

The spatiotemporal distribution of cloud-to-ground (CG) lightning activities on the Yungui Plateau is investigated in this study by using a 5-year dataset (2016–2020) from the ground-based National Lightning Detection Network (CNLDN). The correlations between the lightning activities and different meteorological factors in the region are also analyzed. The results show that there is an obvious difference in the spatial distribution of lightning activities on the Yungui Plateau during the 5 years, with high lightning density in the east and low lightning density in the west. The lightning activities shift and gather more towards the eastern plateau especially after 2019. Affected by the quasi-stationary front in Kunming, the spatial distributions of lightning flashes in cold and warm seasons are different. On the other hand, the frequency of the lightning activities varies from year to year, such as the surge in 2019. But in general, 62% of the lightning activities are produced in summer and the lightning flashes occur more often in the afternoon and evening on the Yungui Plateau. Additionally, it is found that lightning activities in the 5 years are closely related to precipitation and temperature, while there is a weak correlation with relative humidity and almost no correlation with sensible heat flux. The analysis also indicates that the CAPE×P (convective available potential energy times precipitation rate) proxy can be effectively used to describe and predict lightning activities on the Yungui Plateau as the lightning flashes corresponds well to CAPE×P, especially of the spatial distribution.
