Connections between Rotating, Stratified Turbulence and Climate: Theory, Observations, Experiments, and Models

05/14/2012 - 7:00am to 05/18/2012 - 4:00pm
CIRES Auditorium at CU-Boulder


The program is codirected by Baylor Fox-Kemper and Keith Julien, (University of Colorado-Boulder) and Annick Pouquet (IMAGe, NCAR).

 Current models and simulations of fluid turbulence in the atmosphere and oceans are conducted at parameters that do not closely resemble observed, realistic values. Thermal and rotational forces are sometimes orders of magnitude too small. Frictional forces are orders of magnitude too large. Multiscale simulations are usually limited on both the grid scale and domain size. Improvements in computing power through Moore's laws will produce minimal advances with present day models. Thus many advances must occur through new model development and associated simulations utilizing extreme parameter values in an asymptotic manner. This will require as well a body of knowledge gained from large-scale direct numerical simulations that explore the nature of moderate to extreme values.

This theme will bring together a focus-group of researchers with primary interest in the above topics and their applications to development of scalings and parameterizations of these processes. The specific goal will be to assess the current status of modeling, identify issues for scientific advancement, and create synergistic activities for near-future efforts, collaborations and funding campaigns.

 The main activities of this program will be a semester long research effort involving theory development, numerical simulations, and tutorials with coordinated by Fox-Kemper and Julien and using NCAR/IMAGe as a hub. A workshop targeted at future directions in rotating and stratified turbulence will be held summer 2012.
