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
Last weekend some scienticts from our research project "Energy transfers in Atmosphere and Ocean" started on an expedition on research vessel Poseidon. Starting point and end point is Punta Delgada on the Azores.
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".
