Synthesized X-band dual-polarization Doppler radar data and the ambient temperature are used to explore the correlation between the microphysical properties and lightning activity of thunderclouds. After pre-processing of the radar data via the Z H-K DP correction, fuzzy logic-based classification of hydrometeors is conducted in a typical thunderstorm process in Sichuan basin, China. The results are combined with the cloud-to-ground (CG) lightning observation for a comprehensive analysis, which show significant correspondence between lightning flash and the solid microphysical particles. In low levels below the freezing level, the CG lightning activity corresponds with heavy rainfall, while it displays graupel or mixed ice-phase particles above the freezing level. The size of graupel echo coincides with the CG lightning activity largely. The CG lightning occurrence is strongly correlated with the convective intensity of thunderclouds, especially the ice-phase particles being dominated by graupel. The strong echo indicates the intensive CG lightning activity very well above the freezing level. Strong CG lightning activity often corresponds to a high cloud top and a large graupel area in the thunderclouds. Consequently, the region of mixed ice-phase particles, especially the region of mixed dry and wet graupel, can be regarded as an important spatio-temporal indicator of the CG lightning activity. Significant linkage between the microphysical properties and lightning activity is revealed above the freezing level in convective clouds in Sichuan basin, which provides a valuable indicator of lightning disasters for numerical weather prediction.

“…For a long time, the research on lightning is mainly based on Doppler weather radar, lightning location instruments, atmospheric electric field instruments and other detection equipment. Relevant researchers in China and other countries have done a lot of in-depth research work on the electrical characteristics of thunderstorm clouds and precipitation and lightning in the process of severe convective weather, and have achieved fruitful research results (Gungle and Krider, 2006;Holle et al, 1994;Dayeh et al, 2021;Jin et al, 2022;Zhu et al, 2023;Liu et al, 2022;Wang et al, 2016;Li et al, 2022;MacGorman and Morgenstem, 1998;Chatterjee and Das, 2020;Zhang et al, 2015). Serge and Serge, (2001) obtained the relationship between lightning and precipitation through the study of lightning location data, and found that lightning and precipitation are highly consistent in space.…”

Based on multi-source observation data such as lightning locator, atmospheric electric field instrument and hourly precipitation data from automatic stations, the lightning characteristics of the strong convective weather process under the influence of the northeast cold vortex in Nanjing Jiangsu Province on 15 June 2020 was analyzed in depth, and the relationship between the lightning activity and the precipitation was obtained. The results show that this strong convective weather process is formed by the cold air from the back of the northeast cold vortex along the front of the high-pressure ridge and the back of the transverse through southward to the middle and lower reaches of the Yangtze River, which makes the cold and warm air currents converge along the south of the Yangtze River to form the heavy precipitation, and is accompanied by the strong lightning activity in the process of this heavy precipitation. The local thunderstorm electric field in Nanjing is mainly characterized by negative increasing type, positive and negative alternating type, and multi-single thunderstorm electric field, and the thunderstorm activity is mainly dominated by negative ground flashes. During this strong thunderstorm, the stronger precipitation periods corresponded to the stronger lightning frequency periods, and the lightning and precipitation fallout areas showed a consistent spatial distribution. The correlation between the lightning activity and precipitation was analyzed by linear fitting, and the correlation between them is 0.946.

“…In the northern hemisphere, the change of CG was connected with wet bulb temperature (Reeve and Toumi 2010), and it was also related to season, location, time of day (Price and Rind 1994), precipitation (Sang and Gong 2015), and convective available potential energy (Romps et al 2014). Furthermore, CG was relative to quantity of heat, humidity, terrain (Kochtubajda et al 2006;Liu et al 2014), in-cloud water content (Zhang et al 2017), radar echo intensity, and altitude (Mecikalski and Carey 2017).…”

Along with climate change, cloud-to-ground lightning (CG)-caused forest fires are becoming increasingly pronounced. This study employed the Chinese lightning location system data (2009)(2010)(2011)(2012)(2013)(2014)(2015) and worldwide lightning location network data (2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015) to jointly analyze CG characteristics and study the correlation between CG and climate change. The Muli county in southwest China was taken as research area. The CG number showed a clear increasing trend on yearly timescale. We divided CG electric current intensity into six grades and found that negative CG accounted for more than 90% of total CG and, among these, the 3rd and 4th intensity grades accounted for about 70%. To examine the spatial distribution, we focused on lightning-caused forest fires high occurrence seasons. In spring, CG distribution changed from the initial southeast to the northwest, gradually spreading to the whole area of Muli, whereas the CG area gradually moved back to the southeast in autumn. Our research suggested that minimum temperature was the most sensitive temperature to CG change. In March, the relationship between CG and minimum temperature showed a strong positive correlation. Considered jointly, we suggest the CG and related lightning-caused forest fires could increase in the future under an increased minimum temperature and decreased precipitation, especially in March.
