Disturbance effects of SF_6 and H_2O released in ionosphere

WANG Si-cheng,FANG Han-xian,YANG Sheng-gao,WENG Li-bin (Institute of Meteorology,PLA Univ.of Sci.&Tech.,Nanjing 21101,China)  
A 2-D dynastic model is used,including diffusion equation and chemical reaction equation.And two different chemicals(SF6 and H2O) are compared by numerical simulation using finite element simulation(FES).The results show that :(1) Compared to H2O gas,SF6 has slow diffusion speed and large chemical reaction rates,so it can substantially affect the ionosphere and facilitate the formation of ionospheric hole.(2) After 10kg H2O,SF6,H2 and CO2 release,SF6 has the largest disturbance to foF2 in 10 minutes,disturbance amplitude of H2O,H2 and CO2 decrease orderly.
