Characteristics of Fair-weather Atmospheric Electric Field in Tibetan Ngari Prefecture

  • 摘要: 晴天大气电场是一个区域大气电场变化的基准场,是大气电场特性的研究基础。对于具有不同地质条件、地理环境和地形特点的区域,晴天大气电场特征具有明显区别。利用在西藏阿里地震台(80.12°E,32.51°N)安装的一台场磨式大气电场仪于2021年10月10日至2021年11月10日观测到的数据,通过对大气电场数据建模与分析,结合气象条件,得到西藏阿里地区23天晴天条件下的平均卡耐基曲线。经过平滑处理去除仪器噪声的波动,得到西藏阿里地区的晴天条件下的标准卡耐基曲线,进而与北京市昌平区十三陵观测台站(116.23°E,40.25°N)同期的晴天大气电场特征进行对比,并对其电场特性差异和原因进行了讨论。研究结果对分析高原地区晴天大气电场特征具有重要的参考价值和科学意义。
