A mid-level water vapor feature associated with
moderate turbulence was depicted better by the
GOES-12 imager than either of the operational
GOES-8 or GOES-10 imagers. One report of
turbulence aloft was over Alamosa (ALS) CO.

information (from the current sounder)
30Advances 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
