3 WRF Transition  Program Overview:  WRF will support higher resolution, improved accuracy, and more representative 4D M2M forecasts for command and control, mission planning/execution, and mission support systems  Improvements in mesoscale modeling will allow forecasters to focus greater attention on high-risk weather areas and high-risk aviation impact variables  Program Milestones and Schedule:  WRF Oct 2005Extended Operational Testing (EOT) begins  WRF 2.1.2Mar 2006AFWA implementation for EOT  AFWA IOCSummer 2006First operational use  AFWA FOCLate 2007Full Operational Capability

4 WRF Transition EOT Status  AFWA currently running WRF in non-operational mode  Froze code and began operational testing in Oct 05  Testing two 5km and one 15km window in classified environment  Objective and subjective comparisons to MM5  Both real-time and seasonal test cases evaluated  Testing exposed some quality issues  Upgraded to v2.1.2 in Mar 06 and extended testing timeline  Discovered some lingering quality issues  Optimized v2.1.2 to address those issues  Re-initiated operational testing on 24 Apr

5 WRF IOC Testing 27 Mar – 21 Apr Category Overall Average# of responsesHighLow Severe Icing Turbulence3.0 2 Winds Clouds Precip Temp SLP Visibility Scale 1= Much Worse 2 = Worse 3 = About the same 4 = Better 5 = Much better G G G G R G G G R Identified Strengths - WRF probability of detection of convection is higher. - WRF surface moisture convergence better defined where convection would occur. - WRF outperforms MM5 in terms of high level cloud forecast. - WRF outperforms MM5 in terms of surface winds and surface temperature. - WRF surface wind forecast along frontal boundary was better at the 6-hour point. Identified Weaknesses - False alarm rate on forecast convection is higher in terms of coverage and severity. - WRF has a tendency to forecast large areas of convection in mountainous terrain that never occur. - WRF over forecasts low to middle level cloud coverage. - MM5 outperforms WRF in terms of forecast visibility reduction associated with precipitation
