Climate Change

Climate models use quantitative methods to simulate the interactions of the atmosphere, oceans, land surface, and ice. They are used for a variety of purposes from study of the dynamics of the climate system to projections of future climate. NMC participates in research to improve the next generation of climate models.

Coherent Structures and Mixing in Rotating and Stratified Flows

Susan Kurien, NMC Affiliate Researcher, LANL Staff Scientist


This research aims to quantify the emergent length scales of coherent flow structures in rotating and stratified flows and relate those to the characteristic length scales over which mixing occurs.

The coherent structures range from tall and columnar to flat and pancake-like, with characteristic vertical and horizontal sizes vary depending on the relative strengths of the rotation and stratification. The efficiency with which such flows mix a scalar, such as heat or mass density, into the flow will vary across the structures formed. This variation will be analyzed using statistical analysis of a series of large scale simulations with varying parameters of interest. The connection between intrinsic scale and mixing scales will be deduced as a function of the global parameters.
