Мезомасштабная изменчивость средней атмосферы по данным ГНСС спутников

Research output

Abstract

Discussed are results on mesoscale variations in the parameters of the troposphere and stratosphere using data of
low-orbital satellites registering radio signals of the global navigation satellite systems, which were obtained in
the Atmospheric Physics Department of Saint-Petersburg State University. Usage of numerical filters for analyses
of vertical profiles of radio-refraction allows obtaining information about disturbances with vertical scales less
than 8 km. Global structures of mesoscale variances experience essential year-to-year changes at altitudes 2–35
km. Seasonal changes in the mesoscale variances of radio-refraction and temperature are studied. At altitudes
lower than 15 km, the variances are larger at latitudes higher 40–50° in summer seasons of both the Northern and
Southern Hemispheres. At altitudes 25–30 km, the variances are larger in winter seasons. At low latitudes, quasibi-annual oscillations are observed. Reasons for mesoscale variations could be convection, acoustic- gravity waves
and turbulence.
