Waves are also seen in the summer upper mesosphere. A three-dimensional numerical model was used to simulate these waves and to diagnose the physical processes involved. The waves simulated in the model …

WebJan 16, 2014 · Planetary wave activity in the MLT has been observed using meridional winds from the high northern latitude (51–66°N) SuperDARN network used as a “ground-based satellite.” The zonal wave numbers 1 and 2 components have been extracted from daily mean meridional winds and wind anomalies from 25°E to 150°W for the years … WebApr 13, 2024 · Numerical modeling of changes in the zonal circulation and amplitudes of stationary planetary waves are performed with an accounting for the impact of solar activity variations on the thermosphere. A thermospheric version of the Middle/Upper Atmosphere Model (MUAM) is used to calculate the circulation in the middle and upper atmosphere at …
WebSep 1, 1997 · Abstract Planetary or Rossby waves are the predominant way in which the ocean adjusts on long (year to decade) timescales. The motion of long planetary waves is westward, at speeds ≥1 cm s−1. Until recently, very few experimental investigations of such waves were possible because of scarce data. The advent of satellite altimetry has …
