利用一个改进的二维低纬电离层理论模式研究夜间中性风对低纬电离层多量的作用．模式计算结果表明：夜间中性风对低纬F层的影响与纬度、地方时有关．夜间低纬F层峰值电子浓度和峰高及其随时间的变化受中性风的影响与传统观点有所差异．低纬F层参量不只依赖于中性风的方向、强度，还与中性风场空间分布及时间变化率有关．中性风对低纬F层的影响值得重新认识．
An improved two-dimensional low-latitude ionosphere theory model is used to study the effect of night-time neutral wind on the low-latitude ionosphere. The results of model calculation show that the influence of night-time neutral wind on low-latitude F layer is related to latitude and time. The peak electron concentration and peak height of F-stratum at night at low latitudes and its variation with time are different from the traditional viewpoints by the influence of neutral wind. The low-latitude F-layer parameters depend not only on the direction and intensity of the neutral wind, but also on the spatial distribution and the time rate of change of the neutral wind field. The influence of neutral wind on F-layer at low latitude deserves re-understanding.
