GMAO RESEARCH HIGHLIGHTS

Research in the GMAO emphasizes the use of satellite observations in global modeling systems, comprised of atmosphere, ocean, land-surface, and biogeochemistry model components. These components are integrated for assimilation and forecast systems to address questions about climate variability, water and energy budgets, composition, and weather and climate prediction; to form an integrated Earth system analysis; and to contribute to the design of future satellite missions.

Details about refereed scientific papers published by the GMAO staff are compiled on our GMAO Publications page.

This page lists titles and links to GMAO Research Highlights. These writeups are summaries of selected GMAO scientific research activities.

2014

This study demonstrates that realistic Tropical Cyclone activity can be simulated in GCMs with a resolution of about 25km and that modifications to the convective parametrization can lead to further improvements in the realism of the TCs.
