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 Stephan Juricke published a new paper together with our PIs Sergey Danilov and Marcel Oliver as well as our other Postdoc Anton Kutsenko in the Journal "Ocean Modelling" titled: "Ocean kinetic energy backscatter parametrizations on unstructured grids: Impact on mesoscale turbulence in a channel".
Our fifth annual workshop was held in collaboration with the SFB 1114 "Scaling cascades in complex systems" and the SFB 1294 "Data Assimilation" in Potsdam, Griebnitzsee Campus, April 2-4 2019.
Our third TRR 181 Winter School took place at the youth hostel in Ratzeburg. More than 40 PhDs, Postdocs and PIs enjoyed sun and science near the lake in Ratzeburg.
The TRR 181 seminar is held every other week in the semester and as announced during semester break. The locations of the seminar changes between the three TRR181 locations, but is broadcastet online for all members of the TRR.
The joint seminar of the Institute for Oceanography and Max Planck Institute for Meteorology is held every other week.
The objective of this course is to provide an opportunity for junior researches to obtain a first-hand introduction to contemporary coherent structure detection techniques and computational algorithms.
