Other AbstractThe CHAMP satellite data is used to analyze the characteristics of the thermospheric density during 12 different intensity geomagnetic storm events from 2002 to 2008,and the distribution characteristics of NRLMSISE-00 model during the corresponding magnetic storm events are studied.The results show that during large geomagnetic storms,the time delay of the peak thermospheric density from high latitude to low latitude is 2 hours,while the time delay during medium and small geomagnetic storms is about 3 to 4 hours.The distribution of thermospheric density in spring and autumn is basically symmetric between north and south,while in summer and winter the thermospheric density of summer hemisphere is greater than that in winter hemisphere.The thermospheric density in spring and autumn is greater than that in summer and winter.The thermospheric density obtained by the NRLMSISE-00 simulates well the pattern of the hemispherical distribution and seasonal distribution characteristics,but the simulation is smaller than the measurements.The peak change of Dst index can reflect the change of atmospheric density better than the peak change of ap index.
