DTC Accomplishments

Strong working relationship between central DTC partners (FSL and NCAR), NCEP, and AFWA.
Completed the basic WRF Reference Code, including NCEP Nonhydrostatic Mesoscale Model (NMM) and NCAR Advanced Research WRF (ARW) dynamic cores
Ported NCEP Post and Verification codes and the NMM code to FSL computer. These codes were also transferred to NCAR, & AFWA computers
Tech transfer: WRF ARW core was implemented at NCEP for real-time predictions as part of WRF Initial Operating Capability (IOC)
Completed WRF Test Plan:
– Critical for WRF IOC at NCEP by October 2004,
– Began evaluating results—presented initial finding at the WRF workshop in June 2004
Real-time cloud resolving (4-km) WRF experiment over Midwest (May-July
First ensemble WRF application developed (in support of predicting winter road
conditions for NHWA)
First use of WRF in an operational forecast environment with displays on AWIPS (at
the Jacksonville WFO)
Obtained needed support to initiate a DTC visiting scientist program in summer 2004

Bill Gallus and Isidora Jankov (Iowa State University)
– Sensitivity of WRF warm season forecasts to changes in physics, dynamic core and grid resolution
– Verification techniques
– Fastest version of WRF that still allows convection resolving resolution (grid spacing, physics time-step, fastest physics)
Dave Dempsey (San Francisco State University)
Investigate optimal model physics for WRF (cloud microphysics, precipitation, and boundary layer)
– Develop and test additions to the WRF physics
Ying Lin (NCEP)
Develop a "Relaxed Threat Score" and other verification techniques.

Determine configuration of WRF that can be run at cloud-resolving resolutions in the High Resolution Window (HRW)
Optimal configuration of ensemble for the HRW
Conduct a Hi-Res WRF real-time winter forecast experiment over the CONUS
Continue visitor program:
- Begin making NMM core available to the community
Convene the first Advisory Panel meeting
Complete a DTC Terms of Reference
