TL;DR: In this paper, the authors used a bulk Richardson number approach to determine the planetary boundary layer height over Europe, based on daily radiosonde observations at 25 stations during 1973-2010.

TL;DR: In this article, the authors presented a near-global view of high-resolution radiosonde-derived boundary layer height and provided a quantitative assessment of the four frequently used reanalysis products, ERA5, MERRA-2, JRA-55, and NCEP-2.

TL;DR: In this article, the background dynamical structure exhibits evident latitudinal and seasonal variations and has a profound influence on inertial gravity waves in the TLS, and the observations reveal that the tropospheric gravity waves are mainly controlled by their excitation sources, implying the wave characteristics may be regarded as (at least an indicator of) the wave excitation source characteristics.

TL;DR: In this article, the authors simulated the nonlinear propagation and evolution of gravity wave packets in a compressible, nonisothermal and dissipative atmosphere, and showed that the influence of constant molecular viscosity on the characteristics (energy propagation path and wave parameters) of gravity waves is insignificant.

TL;DR: In this paper, the 6-day wave effects on the ionosphere were modeled using the Time-General Circulation Model (TIME-GCM) with a zonal wavenumber 1 at the model lower boundary.
