Abstract:	摘要： In this study, ground-based observations of equinox diurnal tide wind fields from the first CAWSES Global Tidal Campaign are compared with results from five commonly used models, in order to identify systematic differences. WACCM3 and Extended CMAM are both self-consistent general circulation models, which resolve general climatological features, while TIME-GCM can be forced to approximate specific conditions using reanalysis fields. GSWM is a linear mechanistic model; while GEWM is an empirical model derived from ground-based and satellite observations. The models resolve diurnal tides consistent in latitudinal structure with observations, dominated by the upward propagating (1,1) mode. There is disagreement in the magnitudes of the tidal amplitudes and vertical wavelengths, while differences in longitudinal tidal variability indicate differences in the nonmigrating tides in the models. These points suggest inconsistencies in model forcing, dissipation, and background winds that must be examined as part of a coordinated effort from the modeling community. ► The first CAWSES Global Tidal Campaign was performed during September–October 2005. ► Diurnal tidal winds from ground-based instruments and different models are compared. ► Models and observations consistent in showing bimodal latitudinal tidal structure. ► Disagreement in tidal amplitudes, vertical wavelength, and zonal variability. ► Coordinated effort needed to examine inconsistencies in model parameters. 出版者： Elsevier Ltd 出版日期： 2012-04 出處： Journal of Atmospheric and Solar-Terrestrial Physics, 2012-04, Vol.78-79, p.19-30 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2010 Elsevier Ltd 識別號： ISSN: 1364-6826 識別號： EISSN: 1879-1824 識別號： DOI: 10.1016/j.jastp.2010.12.010
