AbstractOscillations in the wind field due to the “quasi two-day” wave (Q2DW) have been studied using 14 years of Medium Frequency (MF) radar data over Saskatoon (52°N). The results of analyses have shown that the Q2DW exhibits complex seasonal variability: in addition to the well-known strong summer activity the wave also has been found in winter months. In summer the amplitudes of the Q2DW in meridional (NS) and zonal (EW) winds have comparable values, while they tend to be larger in EW winds in winter. The heights of the maximum amplitude are lower in winter than in summer and there are indications of changes in the dominant period of oscillations throughout the year.
