Dropsondes from the NOAA G-IV aircraft and their apparent impact
on Aviation (AVN) model analysis 0000 UTC 1 March 20001 during
PACJET IOP 16. The 12-h forecast low center was 989 mb, while the
observations indicated a central pressure <978 mb, likely 974-976 mb.
The AVN analysis, which included the dropsonde data, produced a 979 mb
low and nearby winds much closer to reality than the previous 12-h
forecast valid at that time.
|
(A) Aviation model 12-h forecat of mean sea level pressure and 1000 mb
winds initialized at 1200 UTC 28 Feb 2001, valid at 0000 UTC 1 March
2001. The track of the NOAA G-IV and approximate locations
of dropsondes launched and transmitted between 2200 UTC
28 Feb and 0245 UTC 1 Mar for assimilation into the operational models
are also shown. Selected dropsonde observations of surface wind and pressure
are shown for comparison.
|
(B) As in (A), but the AVN model output shown is the analysis valid at the
same time as in (A) (0000 UTC 1 Mar 2001), after assimilation of
PACJET G-IV dropsonde observations.
