Equivalent Electrical Discharge Structure of Thunderstorm and Simultaneous Observation of Multi-Station of Cloud Flashes in Zhongchuan of Gansu
甘肃中川地区云闪的多站同步观测及雷暴的等效电荷结构

Using the data from 7-station slow antenna network synchronized by GPS with 1 min resolution during thunderstorms in the neighborhood of Zhongchuan airdrome,Gansu. Through the non-linear least-square solution method,the dipole moment,tropism and location of charges neutralized by ten intracloud lightnings occurred in a thunder storm on August 20,2004 are fitted and analyzed.The results show that five flashes occurred between main negative charge region and lower positive charge region and that other five fl...
