Center for Atmosphere-Ocean Science

The Center for Atmosphere Ocean Science is a unit of the Department of Mathematics, within the Courant Institute of Mathematical Sciences at New York University. A cornerstone of the Center is our PhD in Atmosphere Ocean Science and Mathematics, a companion to the department’s PhD in Mathematics.

  • Predicting fluids flows from Lagrangian drifter observations

    Oct. 30, 2019

    Courant 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 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
