抽象。通过测量来自密度不足的流星尾迹的雷达回波的衰落时间，可以推断出这些雷达回波的离子的双极扩散率。可以预期，这些扩散率随着高度单调增加，类似于中性粘度。在实践中，情况并非总是如此。在这里，我们调查的能力，中性湍流影响流星尾迹扩散率。关键词。气象学和大气动力学（中层大气动力学;湍流）
Abstract. By measuring fading times of radar echoes from underdense meteor trails, it is possible to deduce the ambipolar diffusivities of the ions responsible for these radar echoes. It could be anticipated that these diffusivities increase monotonically with height akin to neutral viscosity. In practice, this is not always the case. Here, we investigate the capability of neutral turbulence to affect the meteor trail diffusion rate. Key words. Meteorology and atmospheric dynamics (middle atmosphere dynamics; turbulence)
