【摘要】 <正>Using six days cross-track wind data from CHAMP, we investigate the high-latitude westward wind gradient and reversal that occurs at fixed longitudes (-120o ~ -30o GLon in the Northern Hemisphere, 150o ~ 210o GLon in the Southern Hemisphere). The driver of the wind gradient at 60o~70o GLat and in the noon sector is investigated via TIEGCM. The wind gradient is driven by the combined effects of the Earth’s geomagnetic field configuration and the energy deposition from the solar wind.更多还原
