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.  Our mission is to advance our understanding of and ability to predict the coupled atmosphere, ocean and ice system through the use of mathematical and computational tools and analysis of observations; and to train the next generation of leading theoretical and computational climate scientists to face one of the most consequential problems of the 21st century.

Diversity, Equity & Inclusion: The Center for Atmosphere Ocean Science comprises students, postdocs and faculty. Our program values equity, diversity and inclusion as essential elements of an effective, safe and ethical research and educational environment.   It is our responsibility to remove barriers to knowledge and resources that limit access for marginalized groups;  to create a safe, respectful, and inclusive environment for all our members and the communities with which we interact; and to continually evaluate ourselves, our program, and our educational and research outcomes to ensure we live up to these standards.

  • Idealized study of how moisture impact the midlatitude atmosphere

    April 12, 2023
    Turbulence phenomenology of the idealized two-layer model

    Marguerite Brown, Olivier Pauluis, and Edwin Gerber recently investigated how moisture gradients and latent heat release impact the energetics of the midlatitude atmosphere using an idealized two-layer model of the midlatitudes with simplified moist thermodynamics. As the moisture content of the atmosphere is expected to increase under climate change, a better understanding of the impact of moisture is necessary to reduce uncertainty about how weather patterns will change.

  • Emergence and sensitivity of hurricane-like vortices in an idealized atmosphere

    Feb. 13, 2023
    Convective patches and hurricane-like vortices

    Mu-Hua Chien, Olivier M. Pauluis, and coauthors investigated the emergence and sensitivity of hurricane-like vortices in a numerical simulation of an idealized atmospheric system. Read More

  • Multiple faculty positions in Climate and Mathematics at Courant

    Sun glint through Earth's atmosphere from space

    CAOS seeks candidates for several open-rank faculty positions, anticipated to begin September 2023. We aim to fill core faculty positions in the CAOS group, as well as two new multi-department cluster positions under the initiative Predicting Climate Change and its Impacts: From the Global to Urban Scale that seeks to create a diverse, inter-disciplinary cohort to devise cutting edge research and curricular development at NYU.   Read More
