             abstract = "We have used the technique suggested by Hocking [Hocking, W. A new 
                         approach to momentum flux determinations using SKiYMET meteor 
                         radars. Ann. Geophys. 23, 2005.] to derive short period wind 
                         variances in the 80-100 km region from meteor radar data. We find 
                         that these fluctuating winds, assumed to correspond to gravity 
                         waves and turbulence, are closely correlated with the vertical 
                         shear of the horizontal tidal winds. This close correlation 
                         suggests that in situ wind shear may be a major source of gravity 
                         waves and turbulence in the MLT. If this is the case, gravity 
                         waves generated in the troposphere and propagating up to the MLT 
                         region, generally assumed to constitute an important influence on 
                         the climatology of the region, may be a less important source of 
                         energy and momentum in the 80-100 kin region than has been 
                         hitherto believed. (C) 2007 COSPAR. Published by Elsevier Ltd. All
