Fueglistaler::Kelvin waves

(<-Back to research).
Equatorial waves are a family of planetary-scale waves which are confined to the equator by the correolis force, which acts as a waveguide. Kelvin waves propagate eastwards and upwards, and provide significant forcing to the QBO in the stratosphere. Much of our work has focused on Kelvin waves near the tropopause; in this region these waves have a comparatively large amplitude, and are the major component of short timescale variability in the region. This means that they are critical for cirrus formation, diabatic mixing and stratospheric dehydration.
