• Strategies for Predicting Statistical Responses in Complex Turbulent Systems

  Nov. 5, 2018
  

  CAOS researchers have developed a general mathematical framework to construct statistically accurate reduced-order models that have skill in capturing the statistical variability in the principal directions with largest energy of a general class of damped and forced complex turbulent dynamical systems.

• Modeling Ocean Uptake in an idealised Southern Ocean

  Nov. 2, 2018
  

  CAOS researchers in collaboration with researchers at Columbia University have investigated tracer fluxes and ocean upwelling in an idealized southern ocean model. The study finds the tracer fluxes to be sensistive to the vertical resolution, despite the reduction in the depths of the vigorously mixed boundary layers. Read More

• Modeling the mélange

  Icebergs are formed by calving, a natural process during which the ends of marine terminating glaciers break off and fall into the ocean. In Greenland, glaciers often terminate in narrow fjords with complex geometries, in which large iceberg becomes stuck for many months, freeze together, and form a sea-ice/iceberg ... Read More

• Unlocking the Kolmogorov code of turbulence

  July 2, 2018
  

  Atmosphere and ocean flows present us with a complicated jigsaw puzzle of energetic motions on many scales, ranging from slow planetary waves on scales of 10,000 kilometers or so all the way down to small-scale three-dimensional turbulence, where dissipation of kinetic energy might take place on a scale of ...
