Ocean Statistics

Senior Scientist: Jin-Song von Storch


In the context of climate variability and climate sensitivity, statistic comes into play when the considered climate component, normally a  large-scale component such as the thermohaline circulation (THC), interacts with other smaller-scale components, such as oceanic eddies or fluctuating fluxes at the sea surface induced by atmospheric variability. On the one hand, the interactions introduce irregularities in the behavior of the large-scale component. On the other hand, they result in statistical terms in a consolidated description of the large-scale component, which need to be expressed to close the description. Due to these interactions, climate sensitivity  depends not only on large-scale dynamical processes and feedbacks, but also on the representation of small-scale variations. The primary mission of the Ocean Statistics Group is to understand these interactions, to evaluate their impact on climate prediction/projection, to identify their effect on climate sensitivity. The main tools are general circulation models, including high-resolution models.


In the long term, the Ocean Statistics Group aims to assess the climate prediction problem from the point of view of statistical physics. Climate predictions deal with changes of statistics of a climate component (e.g. the THC or the global temperature) induced by changes in the external forcing. Performing such a prediction requires the knowledge of the governing equation of the PDF (probability density function) that describes the interaction between the components of interests and the remaining components on a macroscopic level. Even though efforts have been made, systematic derivations of macroscopic descriptions have not been possible and will be an important goal of the Ocean Statistics Group.
