How waves, swirls and turbulence influence our climate

How do turbulence, waves and swirls interact in the ocean and the atmosphere? A large-scale project is investigating the physical laws and mechanisms that control the transfer of energy in the oceans and the atmosphere. This serves to better understand the dynamics of the climate system. The German Research Foundation has now approved the third funding phase for the Collaborative Research Center "Energy Transfers in Atmosphere and Ocean". A dozen universities and institutes are involved in the project, including the Catholic University of Eichstätt-Ingolstadt with Prof. Dr. Marcel Oliver and his team from the Chair of Applied Mathematics.

The law of conservation of energy is well known from physics lessons: The energy of a closed system is constant. It is not lost, but is converted into other forms, for example when kinetic energy becomes heat – or vice versa, when heat leads to movement. However, this basic scientific principle often still poses a problem for climate research. Until now, for example, it has been unclear when calculating ocean currents where the energy that creates small-scale swirls and the mixing processes they cause come from. The same applies to the atmosphere, where air moves instead of water: Here, too, local turbulence can drive larger movements or, conversely, waves can break down into small structures on a larger scale.
