| 摘 要： | 对某一地区大气电场的研究有助于了解该地区大气电场特征,对分析该地区各种天气过程的特征提供很大帮助。本文利用成都地区2009~2015年大气电场资料,分析结果表明:成都地区晴天大气电场日变化基本上呈现出双峰双谷型,峰值出现在06:00和14:00,谷值出现在03:00和22:00;阴天大气电场有明显的双峰值,相对于晴天大气电场值更小;大雾大气电场强度均为正值,电场强度小于该时段晴天大气电场值;雷电条件下地面电场的起始、发展、结束阶段地面电场变化明显。

| Abstract: | Atmospheric electric field over ground helps us understand the characteristics of atmospheric in a given area,to provide great help to different weather conditions characteristics of the process analysis of the region. The characteristics of the near-surface atmospheric electric field are analyzed between 2009 and 2015 in Chengdu. Come to the following results: The sunny days,near-surface atmospheric electric field change was basically showing a double peak to valley type. The peaks were at 06:00 and 14:00,the valleys were at 03:00 and 22:00. It showed some seasonal variation. In the overcast days,the average atmospheric electric field showed the trend of positive change and had two obvious peaks,mean values of the electric field were less than the sunny. Atmospheric electric field strength in the fog process is basically positive. The electric field strength was less than the atmospheric electric field at the same time in the sunny days. Under the thunderstorm conditions,the beginning,the development and the end of the near-surface electric field had the obvious surface electric field changes. |
