abstract = {Zonal asymmetries axe frequently seen in stratospheric
temperature or trace gas fields as surf zones, streamers,
filaments etc. They axe also seen as very small-scale
fluctuations, the intensity of which varies with longitude.
Similar structures might be expected in the mesosphere as
well, and several examples have recently been found. CRISTA
1 large-scale data are presented that indicate a surf zone
in the middle mesosphere at the beginning of winter. Very
small-scale data are shown from the CRISTA 2 mission.
Mesospheric variability is found to be high at all
altitudes, latitudes, and longitudes. There axe considerable
non-zonal structures in these fluctuations. (The duration of
the Crista missions was about one week each.)Zonal
asymmetries have been known for a long time from comparisons
of ground stations measuring the same parameter in the
mesosphere / lower thermosphere As an example, upper
mesosphere temperatures derived from OH* emissions are
compaxed here for Wuppertal and Moscow (Zvenigorod), which
are about 2000 km apart. A systematic and substantial
difference in temperature is obtained, with higher
temperatures at Wuppertal than at Moscow. The difference
appears to follow the solar cycle: it is small at solar
maximum and large (up to 28 K) at solar minimum. The reason
for this surprising behavior is as yet unknown.The Moscow
and Wuppertal temperatures have also been analyzed for
long-term trends: a trend discrepancy between the two
stations is not seen in the data interval common to the two
stations. (C) 2003 COSPAR. Published by Elsevier Ltd. All
