On the scale sizes of wind systems in the meteor zone

Abstract

In view of certain limitations associated with single-station meteor wind observations a two-station experiment has been carried out in order to establish the medium and large scale features of the upper atmospheric wind. It emerges from this study that the major constituents of the wind in the meteor region have considerable scale sizes in the horizontal, usually exceeding several hundred kilometres, and it appears that the dominant structure results from the presence of tidal oscillations and planetary waves while turbulence and internal atmospheric gravity waves are likely to be responsible for the residual wind features. This is also evident from the vertical structure of the wind which has been investigated in this study with the aid of interferometric height finding equipment.
