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.
Being Part of the Team: What TRR 181 PhDs say
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.
The research ship "FS Sonne" cast off on March 20 in the North Sea and will be on the Atlantic Ocean for 67 days to do research activities and collect data from the mooring stations.
Our newsletter comes out every three months and includes information about the work done in our project and more.
From March 10-12, 2021 our new PhDs of Phase 2 met online to get an introduction of the project's topics. Up to 60 TRR 181 members gathered in the three-day Zoom meeting, we are amazed by the positive spirit of everyone!
gender & diversity to go aims to provide a short and concise introduction into gender and diversity matters for researchers at all levels - from students to professors. The lecture series will relate to your day-to-day work and create awareness for dynamics and challenges.
The introductory course on second-moment turbulence closure with Hans Burchard will take place on 23.6., from 2-4 p.m.
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.
