近地环境的电状态

通过电过程的耦合是太阳对气象耦合影响的机制之一,本文扼要地综述了迄今为止人们对近地环境内电流和电场的观测结果以及在此基础上所建立的经验和理论模式;给出了在平均状况下和太阳活动下近地环境电性能的总概貌,重点在靠近地球表面的低层、中层大气区域;着重介绍了该区域内的大气电性能及其受太阳活动的调制. 

Electric Properties in the Near Earth Region

The coupling through electric processes is one of the mechamisms of solar coupling influence on meteorology. Acritical review is given on the observations of electric currents and fields in the near Earth region and on the empirical and theoretical models based on the observations. Abrief picture of the electric properties is therefore outlined in the near Earth region both in average and solar active conditions. Highlight is in the lower and middle atmosphere near the surface of the Earth and especially on atmospheric electric properties and their modulation by solar activities.
