Atmospheric predictability from subseasonal to seasonal time scales and climate variability
are both influenced critically by gravity waves (GW). The quality of regional and global …

The interaction between small-scale waves and a larger-scale flow can be described by a
multi-scale theory that forms the basis for a new class of parameterizations of subgrid-scale …

The transmission and reflection of finite-amplitude, three-dimensional, internal gravity wave
packets across a reflection level are examined numerically in a Boussinesq fluid with a …

Parametrizations for internal gravity waves in atmospheric models are traditionally subject to
a number of simplifications. Most notably, they rely on both neglecting wave propagation …

A generalization of the WKBJ method for the case of coupled modes propagation in
problems of underwater acoustics is proposed. The generalized WKBJ ansatz has the form …

Although internal gravity waves are generally recognized as an important mechanism to
distribute energy through the atmosphere, their dynamics near the instability is only partially …

Weakly nonlinear internal wave–wave interaction is a key mechanism that cascades energy
from large to small scales, leading to ocean turbulence and mixing. Oceans typically have a …

Meridional Overturning Circulation (MOC) is a system of ocean currents spanning thousands
of kilometers transporting heat, salt, carbon, and nutrients to different parts of the ocean. A …

A series of three studies investigates theoretically and numerically the evolution, stability,
and pseudomomentum transport of fully localized three-dimensional internal gravity wave …

Gravity waves (GWs) are one of the most important drivers of middle atmospheric
circulationsand strongly affect the polar vortex of the winter hemisphere. These waves are …
