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.

  • 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

  • Revealing the propagation characteristics of the Antarctic Circumpolar Wave and its teleconnection with the El Nino Soutern Oscillation

    Jan. 3, 2019

    Researchers at CAOS and UWM have studied the Antarctic Circumpolar Wave (ACW) in model and observational data via advanced data analysis techniques. The study has produced a decomposition of the ACW in terms of coherent spatiotemporal modes, some of which exhibit strong teleconnections with the El Nino Southern Oscillation. Read More

  • What limits our ability to characterize the variability of the large scale circulation of the extratropics?

    Dec. 3, 2018

    Courant faculty Dr. Edwin P. Gerber and Patrick Martineau (University of Tokyo) explore how dominant modes of atmospheric variability in the extratropics can be constrained with atmospheric reanalyses. Research finds the spread between reanalyses to be much less than the sampling uncertainty associated with the finite length of reanalysis records. Read More
