The reduction of C uptake (kg/m2) by P limitation. Shown is the difference in the C uptake between the CP simulation and the C-only simulation. The CO2 concentrations during the 21st century correspond to the SRES A1B scenario. From the year 2100 onwards, the CO2 concentration was set at 700 ppm. 

Eddies enclose warm and salty Mediterranean Water. Salty and relatively warm water originating in the Mediterranean Sea flows through the Strait of Gibraltar and afterwards along the Iberian Peninsula into the northeast Atlantic. At an intermediate depth, it flows over a complex topography, which promotes its instability. As a result, strong eddies separate from the main flow and spread into the ocean interior.
The film shows the Mediterranean Water eddies (“meddies”) wandering through the ocean (violet/blue) while rotating clockwise and maintaining in their cores for long periods of time (order of years) the almost undiluted salty and warm characteristics of the Mediterranean Water. Their accompanying oceanic cyclones (shown in green), whose rotation sense is counterclockwise, are seen to interact with the meddies and influence their trajectories.

High Resolution Salinity Distribution. The animation shows the evolution of surface and 300 m salinity over the course of one year, from a high-resolution ocean simulation. At the large-scale, high surface salinities are found in the subtropics,  while lower salinities are found in the tropics and subpolar/polar regions. Their distribution resembles closely the corresponding mean annual distribution of surface freshwater flux (i.e. evaporation - precipitation - river runoff – sea ice melting). The animation also illustrates the large spatial and temporal salinity variability arising from the strong eddy activity, both at the surface and 300m depth.  

Thomas Keitzl, PhD student in the independent Max Planck research group “Turbulent Mixing Processes in the Earth System” at the Max Planck Institute for Meteorology (MPI-M), won the third prize of the Max Planck Award 2014 for his visualisation of the turbulent flow beneath an ice sheet. The award honors the best scientific visualizations from all Max Planck Institutes.

Keitzl's visualisation shows a volume rendering of the temperature field beneath an ice sheet. The cold fluid particles (bright) unite more mass per volume and congregate to thin streaks that push downward through the surrounding warmer fluid (dark), which is in turn transported to the ice and enhances the melting.

This animation presents a climate study of the Hamburg storm surge in 1962. It shows the global wind- and pressure fields in a very highly resolved ECHAM6 (T255L95) simulation of the last decades (left) and of NCEP1 (T62L28) reanalysis data (right) from Feb. 10th until Feb. 28th 1962. In the night from 16th to 17th the winter storm “Vincinette” triggered a heavy storm surge along the whole German North Sea coast and caused gusts in Hamburg up to the strength of Beaufort 12.
