Advances Provided By HES
A Geosynchronous Interferometer (HES) will* depict water vapor as never before
- mesoscale features of moisture for short-term forecasting* characterize life cycle of clouds
- ice / water cloud- cloud particle sizes
(better cloud initializations within models)* measure surface temperatures (land and sea)
- improved SSTs * distinguish atmospheric constituents with improved certainty
- volcanic ash (useful for aircraft routing)
With complementary improved weather observing system, HES* enables the best mix of observations of weather systems
Using improved NWP models, HES provides* improved winds at more levels for hurricane intensity and trajectory forecasting* improved high resolution moisture / temp fields for QPF* improved cloud information with 4DVAR assimilation for better 2-3 day forecasts
