to get a total is not the way snow is measured. BUFKIT 10.6 provides
a new “Snow Accumulation” plot to align hourly model output with official
snow measurement procedures.
BUFKIT 10.7 provides many keyboard shortcuts for commonly used
functions. Examples include the arrow keys to navigate through time
and ensembles, and the “E” key to toggle ensemble elements on and off.
Three new CAPE-Shear diagrams are available on the profile panel.

- BUFKIT 10 has
not been optimized for performance and requires more processing capability
when working with ensembles. Slower computers may not be responsive.
- 2. BUFKIT 10 has
been tested under Linux using WINE and is about 90% functional with a
default installation. However, with a small modification to the default
Linux/WINE install Bufkit 10 is close to 100% functional under Linux.

BUFKIT Ensemble Production
To support WDTB’s instructors and research associates participating training development.
1) Model: The workstation WRF
2) Resolution: 24 KM
3) Frequency: 00Z and 12z
4) Ensemble Elements: There are 16 ensemble elements available. The elements vary by selecting different workstation WRF options.
Start Boundary Initialization at:
Forecast Hour 06
Forecast Hour 00
5) Domain: There are about 1000
ensemble profiles in the domain:
6) Progressive BUFKIT Ensemble Profile Production.
We do not wait for all ensemble elements to be generated before posting the profile to the web. As soon as an ensemble element becomes available, we’ll regenerate and post the updated profile.
7) You can use BUFGET to download the BUFKIT Ensembles.
BUFGET has pre-defined scripts that allow you to download profiles by state.
