| The current human space activities become more and more frequent, the earth magnetic layer disturbance as one of the important factors which influence the space weather, the origin, change and the influence of which on human space programs and the production and living have been one of the focus of many scholars’studies. The research on Earth magnetosphere’s response to the solar wind disturbance, the process and its change rule has important significance in helping us understand the SMI coupling system.This paper mainly discusses the influences on the earth’s magnetosphere disturbances caused by different solar wind pressure. Interplanetary magnetic field and the solar wind pressure are the main factors which change the earth’s magnetosphere, between which, the influence of the solar wind pressure is particularly important. The increase or decrease to a certain extent will cause the compression or release of the magnetosphere, and indirectly affect the magnetic field, leading to a global changing of the magnetic layer. Synchronous orbit of earth’s magnetic field and ground magnetic field are susceptible to the ground current and ionosphere current’s impact. Through the example analysis of ACE and GOES satellites’observation data, get the relationship between the geosynchronous orbit magnetic and the earth horizontal magnetic field’s responses under the effect of different solar air pressure pulse, then to obtain the different influence on different regions caused by the change of the current system of the magnetic layer. Finally, we also use SWMF model for analyzing the influence factors of the pneumatic pressure drag attenuation coefficient K, found that the sun pneumatic pressure drag attenuation coefficient K is mainly influenced by the pneumatic pressure and the north and south direction of the interplanetary magnetic field effect, and the K value with the change of the influence factors is certain linear relationship. |
