First observational evidence for the role of polar vortex strength in modulating the activity of planetary waves in the MLT region
Based on the meteor winds measured at Mohe (MH; 53.5° N, 122.3° E) and the reanalysis
data, we investigate the variations of planetary waves in the mesosphere and lower …
