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.

  • Statistical forecasting of the El Nino Southern Oscillation

    Feb. 25, 2020

    CAOS researchers Xinyang Wang and Dimitris Giannakis in collaboration with Joanna Slawinska of University of Wisconsin-Milwaukee have developed a data-driven technique for statistical forecasting of the El Nino Southern Oscillation (ENSO), based on a combination of kernel methods for machine learning with techniques from operator-theoretic ergodic theory.  Read More

  • Untangling waves and vortices from limited observations

    Feb. 6, 2020

    CAOS researchers H. Wang and O.Bühler have developed a numerically robust algorithm to decompose the 1-D energy spectra obtained from ship/aircraft data sets.  This work is featured in Focus on Fluids by Journal of Fluid Mechanics. Read More

  • 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.
