Workshop on Internal Tides, April 23–24, 2024

This workshop addresses the generation, propagation and breaking of the internal tides, as well as the effect on the general circulation. The workshop takes place in the Rossby Hall at the Department of Meteorology, Stockholm University.

Internal tides are internal waves with tidal freuqency that are generated by tidal flow over rough bottom topography in the ocean. They are the largest source of internal waves in the deep ocean. Breaking internal waves is the main reason for vertical mixing, and this mixing is crucial for the deep circulation.

Everyone is welcome to listen to the talks.
