| Research Abstract |
We have developed a general circulation model (GCM)which covers all the atmospheric regions : namely, from the ground to the top of the thermosphere (about 700 km altitude). Both form the numerical simulations and radar observations, we found significant variations of the polar cap thermosphere and ionosphere, which would be be-yond our understandings. In addition, in the low-latitude thermosphere, we also success-fully simulated the midnight temperature maximum (MTM)which cannot be reproduced from previous GCM simulations.
