摘要: Abstract We present numerical results for the m =1 meridional winds of semidiurnal oscillations in high-latitude upper mesosphere, which are generated Numerical Spectral Model (NSM) without solar excitations tides. Identified with heuristic computer runs, pseudo-tides attain amplitudes that are, at times, as large non-migrating tides produced standard forcing. Under influence parameterized gravity waves, nonlinear NSM generates internal like quasi-biennial oscillation, periods favored by dynamical properties system. The Coriolis force would favor polar latitudes excitation 12 h periodicity. This oscillation may help explain observed region ground-based and satellite measurements.
