Center for AtmosphereOcean 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.

Understanding the atmospheric response to volcanoes
Feb. 7, 2019Recent 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, 2019Researchers 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, 2018Courant 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

Strategies for Predicting Statistical Responses in Complex Turbulent Systems
Nov. 5, 2018CAOS researchers have developed a general mathematical framework to construct statistically accurate reducedorder models that have skill in capturing the statistical variability in the principal directions with largest energy of a general class of damped and forced complex turbulent dynamical systems.
