Imbalance refers to the departure from the large-scale primarily vortical flows in the
atmosphere and ocean whose motion is governed by a balance of Coriolis, pressure …

Whereas high-frequency waves are valid solutions to the Boussinesq equations in certain
limits, their amplitudes are generally observed to be small in large-scale atmospheric and …

In the presence of inertia-gravity waves, the geostrophic and hydrostatic balance that
characterises the slow dynamics of rapidly rotating, strongly stratified flows holds in a time …

Inertia–gravity waves (IGWs) play an essential role in the terrestrial atmospheric dynamics
as they can lead to energy and momentum flux when propagating upward. An open …

tropopause. Proc. Eighth Int. Symp. on Stratified Flows, San Diego, CA, IAHR, 7 pp …

We derive a semi-geostrophic variational balance model for the three-dimensional Euler–
Boussinesq equations on the nontraditional f-plane under the rigid lid approximation. The …

This thesis aims to disentangle internal gravity waves from balanced flow to investigate their
role in the downscale transfer of energy in the ocean by using two conceptually different …

This thesis studies balance models for a rotating stratified three-dimensional fluid on a
tangent plane with full Coriolis force. Derivations are done for two different regions, namely …

The near-tropopause energy spectrum obeys a–5/3 power law at mesoscales. Some
theories accommodating this fact assume ageostrophic dynamics but ignore the abrupt …
