Predicting fluids flows from Lagrangian drifter observations
Oct. 30, 2019Courant researchers M. A. Mohamad and A. J. Majda studied how Lagrangian observations can be used to recover Eulerian properties of a fluid flow using data assimilation techniques. They show how exact and approximate algorithms, which combine observations with a model, can be used to predict Eulerian properties of the flow field.

A fluxbalanced fluid model for plasma edge turbulence with coherent zonal jet creation
June 12, 2019Courant researchers A. J. Majda, D. Qi, and A. J. Cerfon propose a fluxbalanced 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 largescale 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, 2019A 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 MaddenJulian Oscillation (MJO) in an idealized GCM. Read More

Reconstructing dynamics of chaotic systems using approximate eigenfunctions
March 22, 2019A 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
