| description abstract | A space-time spectral analysis is applied to the daily 500 mb geopotential field (gridded along 50° N) of five winter seasons (1972?77). The results are displayed in the wavenumber-frequency domain as two-sided frequency spectra of meridional geostrophic wind and one-sided spectra of geopotential. They show three isolated spectral peaks: stationary ultralong waves (k = 1?4, p ≈ 25 days), and eastward propagating long (k = 5?6, p ≈ 10 days, c ≈ 6 m s?1) and short waves (k = 7?8, p = 4?6 days, c ≈ 10 m s?1). In the wave-number-frequency domain only the magnitudes of the peaks vary from one season to the other. | |
