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 PI Thomas Jung and Sergey Danilov as well as our postdoc Nikolay Koldunov contributed toa new paper in the "Geophysical Research Letters" titled: "Intensification of the Atlantic Water Supply to the Arctic Ocean Through Fram Strait Induced by Arctic Sea Ice Decline".
From Febuary 4-6 our early career scientists met in Ratzeburg for our annual Winter School. This was the last winter school for this phase.
After the great success of the first COMMODORE Workshop in Paris, the second workshop was organised as the Hamburg COMMODORE Conference during January, 28-31 2020 at MARKK (Das Museum am Rothenbaum – Kulturen und Künste der Welt).
The review for the second phase of the TRR 181 is held in Bremen March 18-19.
The TRR 181 “Energy transfers in Atmosphere and Ocean” in collaboration with the International Research Training Group “ArcTrain” organizes a one-day symposium to raise awareness for these gendered dynamics and to foster a gender and diversity-sensitive approach to the promotion of early career scientists. Invited are leading gender studies scientists to present their work and to offer workshops for our members and PIs to learn about the science that stands behind the numbers and theories in the field of gender studies.
