Research project Oceanic and Atmospheric Overturning Circulation
By studying the oceanic and atmospheric overturning circulation it is possible to for example track the heat, salt and moisture exchanges between the low and high latitudes.
Figure 1 shows how this is viewed by cells, which transport water and air in the coupled ocean-atmosphere system simulated with the Earth system model EC-Earth.
An alternative way to study the overturning circulation is with Lagrangian trajectories, which makes it possible to follow a given water or air mass from a given region to another. For this we have developed the trajectory model TRACMASS (www.tracmass.org) for both air masses and water masses.
In Figure 2a and 2b we have followed water in the atmosphere from evaporation regions in the Tropical Pacific to the precipitation points.
