对热层中氢原子的日变化进行了理论计算，同时以一致的方式评价了热层旋转、热逃逸、与O+离子的电荷交换、与热H+离子的电荷交换、风的输运和弹道通量的影响。前五种影响导致了与零净弹道通量条件的显著偏离。一个热层风速为50m的S−1的离基高度和总的电荷交换通量从0到2×10 8 cm−2 S−1与观测结果一致。
Theoretical calculations of the diurnal variation of atomic hydrogen in the thermosphere are presented that simultaneously evaluate the effects of thermosphere rotation, thermal escape, charge exchange with O+ ions, charge exchange with hot H+ ions, transport due to winds, and ballistic fluxes in a consistent manner. The first five effects cause a significant departure from the zero net ballistic flux condition. A thermospheric wind with a peak velocity of 50 m s−1 at exobase altitude and a total charge exchange flux varying from 0 to 2 × 108 cm−2 s−1 are found to be consistent with the observations.
