The Global Climate and Weather Modeling Branch conducts a program of
research and development in support of the National Centers for
Environmental Prediction (NCEP) operational forecasting mission for
global prediction for medium range (3-14 days) and for extended range
(week2 – S/I). This research and development in global modeling includes
four dimensional data assimilation of satellite and conventional
observations on a global scale, advanced numerical techniques for
modeling the atmosphere and interactions between the atmosphere, ocean
and land surfaces, parameterization of sub-grid scale processes in the
atmosphere, ocean and land surfaces, hindcast of the coupled model for
S/I calibrations, international aviation product development, diagnostic
studies of global model performance, data quality control and evaluation
of new observing systems, and support for tropical prediction. The
Global Modeling Branch publishes research results in various media for
dissemination to the world oceanographic and meteorological community.
