摘要：

A time‐dependent two‐dimensional numerical model of the minor neutral constituents in the thermosphere is used to examine the effects of winds in altering the local distribution of NO produced in the aurora. The calculations show that thermospheric winds flowing through regions of enhanced local auroral production produce a “plume” of enhanced NO densities downwind from the aurora. The maximum NO densities calculated with and without horizontal winds differ by a factor of 2.6 for the case consideredindicating the importance of horizontal transport in controlling NO densities within the auroral zone. © 1979 by the Chinese Geophysical Society
