Combining experiments with simulations
Scientists in Area T use experiments as well as simulations to investigate the ocean and atmosphere. High-resolution measurements are used e.g. to construct horizontal and vertical wavenumber power spectra or to construct energetically consistent parameterizations of energy transfers. Furthermore, observations with high-resolution data and simulations help assessing the mixing processes active in a descending gravity plume.
Specific research questions in Area T are:
- How to quantify and parameterise stratified turbulence in the atmosphere?
- What are processes, energy transfers and interactions between small-scale turbulence, gravity waves and eddies in the surface and bottom boundary layers of the ocean?
