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.
Our Postdoc Nikolay Koldunov published a new paper with our PI Thomas Jung and Postdoc Patrick Scholz in the Journal "Geoscientific Model Development" titled: "Scalability and some optimization of the Finite-volumE Sea ice–Ocean Model, Version 2.0 (FESOM2)".
Our postdoc Valerio Lembo and our PI Valerio Lucarini contributed to a new paper published in the journal "Geoscientific Model Development" titled: "TheDiaTo (v1.0) – a new diagnostic tool for water, energy and entropy budgets in climate models".
Our PIs Gualtiero Badin, Christian Franzke, Marcel Oliver and Jens Rademacher contributed to and edited a new special issue published in the Journal on "Geophysical & Astrophysical Fluid Dynamics" titled: "Mathematical Developments in Geophysical Fluid Dynamics: Structure, Vortices, and Waves".
Our retreat is held September 17-19, 2019.
Numerous research institutions from Bremen and Bremerhaven including TRR181 are participating in the research mile as part of the 12th Maritime Festival Week 2019.
The editors of the TRR181 publication "Energy transfers in Atmosphere and Ocean" will present the book at the Frankfurter Buchmesse 2019.
