• A flux-balanced fluid model for plasma edge turbulence with coherent zonal jet creation

  June 12, 2019
  

  Courant researchers A. J. Majda, D. Qi, and A. J. Cerfon propose a flux-balanced model to improve the understanding of plasma edge turbulence and creation of zonal structures and develop a theory to address the generation and persistence of large-scale coherent flow structures in these models.

• Upscale Impact of Mesoscale Convective Systems and Its Parameterization in an Idealized GCM for an MJO Analog above the Equator

  April 22, 2019
  

  A recent study by CAOS researchers Qiu Yang and Prof. Andrew Majda in collaboration with Mitchell W. Moncrieff from NCAR investigates the upscale impact of mesoscale convective systems (MCSs) on the Madden-Julian Oscillation (MJO) in an idealized GCM.  Read More

• Reconstructing dynamics of chaotic systems using approximate eigenfunctions

  March 22, 2019
  

  A recent study by Suddhasattwa Das, Dimitrios Giannakis, and Joanna Slawinska investigates a phenomenon / object called approximate eigenfunctions to forecast dynamics of chaotic systems over arbitrary time scales. Read More

• Understanding the atmospheric response to volcanoes

  Feb. 7, 2019
  

  Recent work by CAOS researchers Kevin DallaSanta and Ed Gerber with Matthew Toohey (GEOMAR Kiel) investigates the influence of volcanic eruptions on weather and climate using a hierarchy of models of varying complexity. Read More
