GMAO Seminar Series on Earth System Science
Upcoming:
⋄ GMAO Seminar Series on Earth System Science ⋄
Speaker: Aneesh Subramanian, University of Colorado Boulder
Location: on-line
Time: 10am
The relative merits of different ocean observation systems (moored buoys, Argo, satellite, XBTs and others) are evaluated by their impact on ocean analyses and subseasonal forecast skill. Several ocean analyses were performed where different ocean observation platforms were withheld from the assimilation in addition to one ocean analysis where all observations were assimilated. These ocean analyses products are then used for initializing a set of subseasonal forecasts to evaluate the impact of different ocean analyses states on the forecast skill. Results from the NASA GMAO and the European Centre for Medium-Range Weather Forecasts (ECMWF) assimilation systems and ensemble prediction systems’ experiments will be presented to highlight changes in the ocean analyses states in the tropical Indian and Pacific Ocean and their impact on the forecast skill from weather to subseasonal timescales. Coupled air-sea interaction processes relevant to weather and intraseasonal variability in the earth’s climate system are inadequately represented in regional and global coupled models. These inaccuracies could be related to either poor parameterization of model physics or insufficient model resolution to resolve the critical processes. New efforts in observations, process understanding and translation into weather and climate models are necessary for improvements in simulation and prediction of the intraseasonal variability and associated weather events. We will discuss the merits of different observation platforms in this context and future observation and model improvement pathways.

GMAO RESEARCH THEME MEETINGS:
The GMAO Research Theme Meetings are open only to GMAO members. These internal meetings, provide an opportunity for GMAO researchers to present new research results to their colleagues and to discuss their work and its implications for GEOS systems. Each year, two seasons of meetings are held on roughly two Thursdays each month.
