MIDDLE ATMOSPHERIC WINDS AND TIDES OVER LONDON, CANADA (43-DEGREES-N,81-DEGREES-W) DURING 1992-1993

Mean winds and tides have been measured with the new MF radar at Londo n, Ontario. Using a 1-year continuous set of data, the mean winds are compared with a recent empirical model. The diurnal and semidiurnal ti des are discussed, and these are compared with results from other simi lar midlatitude ground-based radars. There are interesting similaritie s and discrepancies, although we note that some of the initial compari sons use data from different years. The diurnal and semidiurnal tides are also compared with recent tiadel models. Tidal characteristics are generally consistent with the models, but again some differences are also noted.
