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 PhD Gökce Tuba Masur and PI Marcel Oliver published a new paper in the journal for "Geophysical & Astrophysical Fluid Dynamics" titled: "Optimal balance for rotating shallow water in primitive variables".
Our newsletter comes out every three months and includes information about the work done in our project and more.
On Wednesday, Febuary 26, our first output of the ART&SCIENCE Collaboration with art grad students kicked-off at houseboat "Schute" in Wilhelmsburg, Hamburg. It was great success - for the scientists and for the non-scientists!
