July 1: Cloud composite plot change:
The "Cumulus Cloudbase for Cu Potential > 0" was often missing small
regions where the Cu potential was in fact greater than zero.
That has now been altered to "raster" plotting, which will ensure that
all locations with a positive Cu potential will be displayed.
Dec 10, 2005: Plot "frame" change:
RASP plots contain a dashed line "frame" indicating an outer zone of
decreased confidence resulting from mismatches between the coarse and
fine nested grids near the boundary. A recent WRF model
alteration doubled the width of the smoothed zone near the boundary so
the "frame" border has been increased to reflect that change.
Nov 6: Cloud Parameter Changes:
I've altered the cloud parameters by removing the previous
"OvercastDevelopment" parameters and replacing them with forecasts for
"Extensive CloudBase" and "BL Cloud Cover". "Extensive
CloudBase" is a replacement for "OvercastDevelopment", based on a
model-predicted cloud water prediction. "BL Cloud Cover" is
based upon the relative humidity in the BL and while overly simplistic
can still be useful.
Nov 2: World-wide accuracy improvement:
Finally - after beating my head against mysteries with few clues for
the past three days, I figured how to to uncompress the new "GRIB2"
files produced by NCEP's GFS (Global Forecast System), allowing use of
GFS predictions at 0.5x0.5 degree resolution (about 50km) to
initialize the non-US forecasts (I've been using GRIB1 files with
100km resolution). So I've now changed to their use for the
SW_SOUTHAFRICA and GREATBRITAIN runs, which should result in improved
accuracy of larger-scale (non-terrain-generated) features such as the
position/movement of fronts and upper-level clouds.
Oct 30: Meteorological model updated:
Today I upgraded my WRF meteorological model to the latest version
available, which has several bug fixes and in particular should reduce
boundary matching problems (which are occasionally apparent in the
region between the domain boundary and the dashed-line "frame").
After correcting some problems I believe I now have it working
properly, but will keep an closer-than-usual eye on the processing for
the next day.
