@article{Perez2022UnidirectionalMI, title={Unidirectional Modes Induced by Nontraditional Coriolis Force in Stratified Fluids.}, author={N. Perez and Pierre Delplace and Antoine Venaille}, journal={Physical review letters}, year={2022}, volume={128 18}, pages={ 184501 } }

Using topology, we unveil the existence of new unidirectional modes in compressible rotating stratified fluids. We relate their emergence to the breaking of time-reversal symmetry by rotation and vertical mirror symmetry by stratification and gravity. We stress the role of the Coriolis force's nontraditional part, induced by a rotation field tangent to the surface. In contrast with horizontally trapped equatorial waves induced by the traditional component of the Coriolis force perpendicular to…

Topological origin of equatorial waves

A topological origin is shown for two well-known equatorially trapped waves, the Kelvin and Yanai modes, owing to the breaking of time-reversal symmetry by Earth's rotation, which demonstrates that ocean and atmospheric waves share fundamental properties with topological insulators and that topology plays an unexpected role in Earth's climate system.
