Functionally-equivalent T&E suite • Pre-processing (including ability to read binary GFS in spectral coordinates) • Cycled HWRF vortex initialization and relocation • GSI Data Assimilation • Coupled (POM + WRF) model • Post-processing • Tracking • NHC Verification & confidence intervals • Display • Archival • The Developmental Testbed Center • HWRF 2011 Baseline Test Plan • Point of Contact: Ligia Bernardet • December 15, 2010 • Introduction • The DTC will be performing testing and evaluation for the Hurricane WRF system, known as HWRF (Gopalakrishnan et al. 2010). HWRF will be configured as close as possible to the operational HWRF model, employing the same domains, physics, coupling, and initialization procedures as the model used at the NOAA NCEP Central Operations and by the model developers at NCEP EMC. The configuration to be tested matches the 2011 HWRF Baseline, which is the configuration that served as control for all developments at EMC geared towards the 2011 operational implementation.
General Conclusions: • SAB believes DTC currently risks becoming spread over too many projects and directions. While most activities are relevant, some tasks appear to be peripheral to DTC and critical U.S. NWP goals. • We restructured the DTC tasks for AOP 2011 into five focused areas. We examine all tasks to ensure their relevance to the core missions of DTC. New approach should improve the way we communicate the DTC activities to the outside community. • The SAB believes that these accomplishments, although substantial, have not been sufficient to realize DTC’s core objectives, as noted in the introduction. For example, a functionally equivalent operational environment available for extended period tests is not available, although progress has been made in that direction. • AFWA considers DTC to have a functionally equivalent test environment for AFWA related work. • DTC now has a functionally equivalent test environment for HWRF (including full cycling capability) • Efforts on “functionally equivalent test environment” are needed on mesoscale modeling (e.g., NAM, NEMS, and NMM-B).
General Conclusions: • To date, a substantial amount of DTC effort has been placed on the long-term development of infrastructure in a range of areas, such as MET software package. However, it is time to place increased emphasis on infrastructure utilization that directly addresses DTC’s central goals. • SAB asked DTC to increase testing and evaluation efforts that directly contribute to the core missions of the DTC. • With flat budget, the efforts on community support have to be decreased.
Specific Recommendations and Conclusions • (1) The DTC should give priority to building a functionally equivalent operational environment to test and evaluate new NWP methods for extended retrospective periods and significant events using advanced verification tools. Such an environment should include operations-like data assimilation/cycling. Sufficient resources should be provided to insure this is in place within 12 months. • DTC will place greater efforts on this, particularly related to the mesoscale modeling. Assembling a functionally equivalent environmentwill require enhanced collaboration among several task areas, including mesoscale modeling, hurricane, data assimilation and ensemble efforts. • (2) The SAB was in general agreement that a central role for DTC is to be the nation’s model “scorekeeper” that would track mesoscale model forecast improvement and serve as the key benchmark center for U.S. mesoscale NWP. • DTC will develop a “test plan” for Reference Configuration (RC) testing that can help track mesoscale model forecast improvement. RC testing will include EMC and AFWA operational configurations. Concept will provide a framework for tracking the improvements of WRF systems with releases of new versions. The test plan will be reviewed by SAB representatives, EMC, and MMM. • Increased efforts on T&E will require additional resources at the expense of community support services.
Specific Recommendations and Conclusions • The establishment of a suite of model verification tools by DTC (including, but not limited to the MET package) was appropriate, although several enhancements are still required. For example, plan-view spatial verification is a critical tool that is currently missing from MET. Furthermore, DTC verification should support the full range of mesoscale assets, such as ACARS, NEXRAD and profiler data. However, the current lack of comprehensive, actionable verification statistics for major contemporary U.S. modeling systems (see 2 above) is of some concern and higher priority must be given to making this information available more rapidly, even if that requires redirecting some of the resources currently being provided to construct and support more specialized MET capabilities. • Some of these features are already available in MET. Further enhancement will require additional resources. • DTC will make a contribution to actionable verification statistics for major contemporary U.S. modeling systems, through Reference Configuration testing.
Specific Recommendations and Conclusions • (4) The board notes that DTC has supported workshops on some modeling systems that are not widely used in the community (e.g., NMM model). Such activities may be justifiable, but it may be worthwhile to review whether their current frequency reflects optimal use of DTC resources. • DTC does not hold NMM workshops. • DTC and EMC need to decide on NMM-B (and NEMS) tutorials, as well as Joint ARW-NMM tutorials with MMM for AOP 2012. • (5) The committee believes that although the DTC itself must maintain competency and knowledge in the new NWS model infrastructure (NEMS), for the immediate future there is little requirement for any significant NEMS outreach activities to the research community. • DTC has no plan to start a tutorial on NEMS framework. DTC hired a staff to work at EMC, to gain expertise in NEMS, and will have the ability to implement components of other modeling systems into the NEMS-based EMC operational system for testing and evaluation. • Louis Uccellini believes that the most effective R2O is for the research community to use operational systems for their research.
Specific Recommendations and Conclusions • (6) The general sentiment of the SAB is that, although the NOAA HydrometeorologicalTestbed (HMT) and Hazard Weather Testbed (HWT) are important national endeavors, DTC participation in these activities may be a secondary priority with respect to DTC’s core mission. • Testbed collaborations are important to NOAA • HWT and HMT collaborations are no longer identified as DTC task areas. Rather, they will be DTC special projects that are directly linked to a few DTC focused areas. Efforts are made to ensure that these projects contribute to DTC core missions. • (7) The committee believes that the DTC can potentially play a unique role in bringing the research and operational communities together to examine and address key national NWP problems. Dealing with existing deficiencies in NWP physics parameterizations is one such problem. • For AOP 2011, the DTC will organize a Physics Workshop, in collaboration with EMC and the academic community, to be held in WDC area in August 2011.
Specific Recommendations and Conclusions • (8)… there remained concern on the board that, because DET is inevitably a costly long-term project, it may limit DTC’s ability to demonstrate sufficient short-term value and relevancy to its sponsoring agencies and the NWP community at large. Thus, some difficult resource decisions may become necessary. • DET is an important activity for NWS to realize the goals outlined in the “White Paper”. DTC will continue to explore additional resources to augment and support such effort. • DET needs to quickly demonstrate short-term value and relevancy to the sponsoring agencies and NWP community at large. • (9)… Based on this experience and a review of previous cycles of the program, the board believes that the visitor program is an appropriate and important element of DTC activities. However, the board believes that the current program casts too wide a net in its request for proposals…Future calls should be crafted to clearly identify one or two mission-critical areas where collaborations with applicants having particularly relevant expertise can significantly augment DTC capabilities and hasten transition of effective NWP solutions to the broader community. • DTC will improve the process for the visitor program for 2011. • Input from MB will be an important part of this process!
Specific Recommendations and Conclusions • (10) Regarding hurricane-related activities, the board felt that there is a need to establish and maintain a reference configuration and operational testbed for the Hurricane-WRF (HWRF). Such a testbed must include a data assimilation component. Furthermore, there is a need for the development and support of relevant diagnostic tools for hurricanes. • The HWRF system maintained by DTC includes a data assimilation component. DTC will include HWRF as a Reference Configuration for testing, with full cycling data assimilation. DTC will also develop and support relevant diagnostic tools, in collaboration with HFIP partners, pending on HFIP support.
AOP 2011 Tasks Testbed collaborations: HWT & HMT DTC activities are distilled into five focused areas HWT & HMT are cross-DTC special projects, with contributions to DTC focused areas identified NEMS is included as part of mesoscalemodeling
Required budget for proposed AOP 2011 activities Total actual funding for AOP 2010 was $5,070K. Total for AOP 2011 is a 8.7% increase.
Future Directions and Challenges • Mesoscale modeling, NMM-B and NEMS • NCEP is moving forward with NMM-B and NEMS, and expects DTC to entrain the community into these operational systems • SAB does not recommend DTC provide community support for NMM-B and NEMS • DTC needs to have a stronger linkage to mesoscale modeling at NCEP (that will contribute directly to NCEP operations). Physics workshop is a start. • Future NCEP short-range ensemble will include NMM-B and ARW in the NEMS framework. • In 2012, DTC needs to decide whether to continuejoint ARW-NMM tutorials (and whether to do NEMS tutorial).
Future Directions and Challenges • Data Assimilation: • NCEP is moving toward GSI-EnKF hybrid data assimilation for global modeling • Multiple EnKF systems are being developed under HFIP sponsorship • AFWA asked DTC to examine a few regional EnKF systems for possible operational use • DTC needs to work with EMC and AFWA to decide on a community hybrid GSI-EnKF system for both regional and global NWP applications. DTC should not support multiple EnKF systems to the community.
Future Directions and Challenges • Hurricane: • DTC made significant progress in merging the operational HWRF code into WRF repository, and in testing the community HWRF code for operation • Needs to assess the impact of EnKF on hurricane prediction • Needs to facilitate improvements made by HFIP community into operations (i.e., Hurricane Test Plan) • Future of operational hurricane model at NCEP: • Will HWRF migrate toward NMM-B on NEMS? • Should we consider migrating toward AHW?
Future Directions and Challenges • Ensemble: • Very good start on the development of the DET infrastructure and first few modules during AOP 2010 • Need to demonstrate sufficient short-term value to operations and NWP community: • EMC: Next generation SREF • HWT: Collaboration with CAPS and SPC cloud-scale ensemble • HMT: Ensemble verification • Making the DET modules available to the community • DET test and evaluation activities will require significant compute resources • Additional resources required to accelerate development
