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.
The 2018 LMS Prize winners were announced at the Society Meeting on Friday 29 June 2018. The TRR181 is very happy to extend its congratulations to Prof. Dr. Valerio Lucarini.
Our fourth annual workshop on "Scales and scaling cascades in geophysical systems" was held from April 4-6, 2018 at "Haus des Sports" in Hamburg, Germany.
Our second TRR 181 Winter School took place at the Hotel Hessenkopf in Goslar starting February 26 to March 3. More than 50 PhDs, Postdocs and PIs faced the cold winds and snow of the German low mountain range Harz to collaborate and learn about the different TRR 181 disciplines and subprojects.
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 TRR 181 locations, but is broadcasted online for all members of the TRR.
The school is co-organized by the Universities of Copenhagen, Oslo, Stockholm and Hamburg. The summer school is supported by the TRR 181.
Our annual retreat is held from September 24-26 at Schlossgut Groß Schwansee.
