On the fast movements of the thermosphere: an interpretation

We examine the oscillations of the meridional neutral wind in the F region as seen by the EISCAT radar. We propose an interpretation in term of eddies ( tourbillons ) of typical size of a few tens to a few hundreds of kilometers. The observed rotation velocity is a few hundreds of meters per second....
