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.
We are happy to announce that the first outcome of our Art&Science Collaboration ENERGY TRANSFERS will be part of the Artville Festival in Hamburg. The theater play OCEANVIEW SUITE is part of the Digital Art Festival, that usually takes place in Wilhelmsburg, Hamburg.
The mini-symposium, initially scheduled to take place at the SIAM Conference on Mathematics of Planet Earth (MPE20), covering current trends in mathematical geophysical fluid dynamics, was cancelled due to the Corona crisis and therefore moved online. The mini-symposium aimed at reflecting relevant cutting-edge developments in the field and providing a forum for young researchers to communicate their work.
Our Postdoc Knut Klingbeil and PI Hans Burchard published a new paper in the "Journal of Geophysical Research: Oceans" titled: "Numerical Study of the Exchange Flow of the Persian Gulf Using an Extended Total Exchange Flow Analysis Framework".
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.
This year the annual TRR181 will due to the Covid-19 circumstances take place online from Septemer 23-25, 2020.
The theater play OCEANVIEW SUITE is part of the Art Festival "ARTVILLE" in Wilhelmsburg, Hamburg July 4-September 29.
