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 still show energetic and mathematical inconsistencies even with the current progress that has been made. This can lead to fundamental errors with climate forecasts. Now ist the right time to combine recent efforts in the different
Our newsletter comes out every three months and includes information about the work done in our project and more.
Our speaker Carsten Eden and PI Dirk Olbers published a new paper in "Ocean Modelling" titled: "A closure for eddy-mean flow effects based on the Rossby wave energy equation".
Our PI Jeff Carpenter published a new paper in the "Journal of Physical Oceanography" titled: "A Physical Interpretation of the Wind-Wave Instability as Interacting Waves".
The school is co-organized by the Universities of Copenhagen, Oslo, Stockholm and Hamburg. The summer school is supported by the TRR 181.
Fundamental aspects of turbulent flows in climate dynamics, July 31–August 25, 2017, Les Houches, France
The Conference will be held at the Henley Business School, Whiteknights Campus at the University of Reading, from 29th August to 1st September 2017. They are currently inviting abstracts for both oral presentations and for posters.
