TRR Session at EGU 2019!

The TRR 181 has its own session at EGU 2019 in Vienna, April 7-12 2019! You can now submit an abstract!

Please consider submitting your abstract to the following session at the EGU General Assembly 2019, 7–12 April 2019, Vienna, Austria, which is closely related to our TRR. So all of you are very welcome to submit abstracts.

Please note that the deadline for travel support applications ( is 1st December. Early career scientists (PhDs & young postdocs) can apply for travel support (typically a waiver for the registration fee).



Energy Transfers in Atmosphere and Ocean

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. 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 the mixing processes they induce, need to be considered, without fully understanding where the energy for their creation originates from.

Similarly in the atmosphere, the conversion of available potential energy into kinetic energy is the key driver of atmospheric dynamics at a variety of scales, from the zonal-mean general circulation to mesoscale convection. Local turbulent processes can drive larger movements or waves on a larger scale can disintegrate into small structures. All these processes are important for the Earth’s climate and determine its evolution in the future.

How exactly the energy transfer between waves, eddies and local turbulences in the ocean and the atmosphere works, often remains unclear. This session wants to discuss this by inviting contributions from oceanographers, meteorologists, climate modelers and mathematicians. We are particularly interested in coupled atmosphere-ocean studies, novel subgrid-scale parameterizations, and energy budget studies of the complex Earth system.

Abstract deadline 10th January 2019.

Deadline for support applications 1st December 2018.
