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 PIs Dirk Olbers published a new paper together with our Postdoc Friederike Pollmann in the "Journal of Physical Oceanography" titled: "On PSI interactions in internal gravity wave fields and the decay of baroclinic tides".
Our Postdoc Anton Kutsenko published a new paper in the Journal "Erkenntnis" titled: "Programming Infinite Machines".
Our PI Hans Burchard published a new paper in the "Journal of Physical Oceanography" titled: "A universal law of estuarine mixing".
The conference is organized by the TRR 181 and held at the MARKK Museum in Hamburg.
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.
Our annual Winter School is held in Ratzeburg again from February 4-7.
