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.
Last week the largest Earth and space science meeting in the world was held in Washington D.C from December 10-14. With 28.000 attendants it was the largest AGU conference since its start. TRR 181 scientists presented their work and collaborated in a joint "Geosciences in Germany" exhibition booth.
Our newsletter comes out every three months and includes information about the work done in our project and more.
Our postdoc Valerio Lembo published a new paper in "Climate Dynamics" titled: "Inter-hemispheric differences in energy budgets and cross-equatorial transport anomalies during the 20th century".
This workshop continues the idea of our November workshop: Have specific workshops to bridge knowledge gaps between the different disciplines.
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 Winter School is held in Ratzeburg from February 11-15, 2019.
