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 PI Gualtiero Badin published a new paper in "Journal of Physics A: Mathematical and Theoretical" titled: "Geometric Lagrangian averaged Euler-Boussinesq and Primitive Equations" together with our PI Marcel Oliver and Postdoc Sergiy Vasylkevych.
Our postdoc Julia Dräger-Dietel published a new paper in "Journal of Physical Oceanography" titled: "Relative Dispersion of Surface Drifters in the Benguela Upwelling Region" together with our PIs Alexa Griesel, Gualtiero Badin and former PI Kerstin Jochumsen.
The Collaborative Research Center TRR 181 "Energy transfers in Atmosphere and Ocean" invites applications for 1 Postdoc position at Helmholtz Center Geesthacht.
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.
On November 7 we organize a meet and greet with Karina von Schuckmann (Mercator Océan) and Sabrina Speich (Ecole Normale Supérieure) in Bremen. This is a collaboration with the BMBF project RACE and the ARCTRAIN graduate school.
Our project members meet at the Literaturhauscafé in Hamburg to talk about the fundamentals of our project.
