Welcome to the Collaborative Research Center TRR 181 ”Energy transfers in Atmosphere and Ocean“
About the project
Energy does not vanish
The energy of a closed system is steady. It is not lost but rather converted into other forms, such as when kinetic energy is transferred into thermal energy or vice versa heat results in a force.
However, this fundamental principle of natural science is often still a problem for climate research. For example, in case of the calculation of ocean currents, where small-scale vortices as well as mixing processes they induce need to be considered, without fully understanding where the energy for their creation originates from. This is similar in the atmosphere, the only difference being that air is moving instead of water. Again, local turbulences can drive larger movements or vice versa waves on a larger scale can disintegrate into small structures.
All these processes are important for the Earth’s climate and determine how temperatures will rise in the future.
Existing climate models show energetic and mathematical inconsistencies which may lead to fundamental errors in climate forecasts. Now is the right time to combine recent efforts in Meteorology, Oceanography and applied Mathematics and to go new ways.
Our Postdoc Friederike Pollmanpublished a new paper together with our Speaker Carsten Eden and PI Dirk Olbers in the "Journal of Fluid Dynamics" titled: "Resolving the horizontal direction of internal tide generation".
Our PI Martin Losch co-published a new paper in the "Journal of Geophysical Research: Oceans" titled: "On the effects of increased vertical mixing on the Arctic Ocean and sea ice".
Our PI Marcel Oliver co-published a new paper in the "Journal of Differential Equations" titled: "A direct construction of a slow manifold for a semilinear wave equation of Klein–Gordon type".
We would like to invite you to apply for the Winter School entitled “Physics and Mathematics of Turbulent Flows at Different Scales”, taking place on February 24th-March 1st 2019 at the Les Houches Physics center based in Les Houches, France.
The TRR 181 seminar is held every two weeks in the semester and as announced during semester break. The locations of the seminar changes between the three TRR181 locations, but is broadcastet online for all members of the TRR.
Our annual workshop is held in collaboration with the SFB 1114 "Scaling cascades in complex systems" and the SFB 1294 "Data Assimilation" in Potsdam, Griebnitzsee Campus, April 2-4 2019.
