| 内容記述 | A review of current knowledge of the effect of solar activity on the thermosphere is presented. Data obtained by the Dynamics Explorer 2 spacecraft and model results from the NCAR Thermospheric GCM, which demonstrate the effect of increased solar and geomagnetic activity on composition, temperature and the dynamic structure of the upper atmosphere are discussed. It is shown how subtle change in the IMF can affect the form of the neutral gas circulation at high latitudes, with important implications for polar orbiting spacecraft. |
