中国多个地区雷暴的层结和地闪特征及其差异
The Stratification and Ground Flash Characteristics of Thunderstorms in Multiple Regions of China and Their Differences
摘要
Abstract
In order to further understand the differences of thunderstorm activity and ground flash charac-teristics between different regions in China,based on ADTD ground flash data from June to August 2011 to 2018,the ground flash within 55 km around 9 regions in southern China and inland plateau during this period was identified,and the ground flash characteristics such as thunderstorm frequency and current in-tensity were counted,combined with corresponding radiosonde data and reanalysis data.The stratification parameters such as warm cloud thickness and convective effective potential energy are calculated,and the stratification characteristics and ground flashover characteristics in different regions are analyzed.The re-sults show that the cloud base temperature and 0 ℃ layer height of the thunderstorm cloud decrease with the increase of altitude,and the cloud base height of the thunderstorm cloud increases with the increase of altitude.Both daytime thunderstorms and nighttime thunderstorms show that the warm clouds depth be-comes thinner with the increase of altitude,which is caused by the decrease of 0℃ layer height and the increase of cloud base height with altitude.The southern region has higher convective effective potential energy,and the convective inhibition energy is not high,so the frequency of thunderstorms and ground flashes is obviously higher than that in the inland plateau region.The distribution of negative ground flash number is similar to that of total ground flash number.The positive ground flash ratio is obviously higher in Lanzhou and Pingliang in the inland plateau region,and the positive ground flash ratio does not linear-ly increase with the elevation.On the whole,the intensity of positive ground lightning flow is greater than that of negative ground lightning flow in the southern region and inland plateau region.The less the num-ber of negative ground lightning flow,the less time period is more likely to produce greater negative ground lightning flow intensity.It is important for us to strengthen our understanding of the characteristics of thunderstorms and ground flashover in different parts of China.关键词
