Workshop on Use of NWP for Nowcasting

October 24-26, 2011
Room 1212, CG1, NCAR, Boulder, CO

Call for papers

. The purpose of the workshop is to explore ways to advance the use of NWP for nowcasting applications. Practitioners, users and developers of high resolution models, data assimilation and nowcasting systems are invited to articulate and define the requirements for NWP in nowcasting applications, and strategically explore and develop a roadmap to bridge the existing gaps between the nowcasting and mesoscale NWP communities.

The workshop on Use of NWP for Nowcasting is sponsored by the World Weather Research Program (WWRP) of the World Meteorology Organization (WMO). The local sponsor of the Workshop is the National Center for Atmospheric Research (NCAR). The Workshop is organized jointly by the Working Group for Nowcasting Research (WGNR) and the Working Group for Mesoscale Weather Forecasting Research (WGMWFR) of WWRP

Specifically, the following topics will be covered in the workshop through presentations and group discussions:
- Use and potential of existing techniques and observation types for nowcasting
- Major physical processes that influence the forecast accuracy for the very-short-term
- Requirements for mesoscale NWP systems, in terms of products, quality, timeliness, etc., from the perspective of nowcasting applications
- Conversely, requirements from mesoscale models on observations, typical problems and limitations experienced on this account
- Experiences to date in, and plans for, application of mesoscale NWP for nowcasting in rapid update cycling systems, the challenges, and potential of various data assimilation techniques
- Different operational setups for nowcasting and longer range, including how to handle issues related to specific location and phenomenon
- Data types that have the most impact for nowcasting purposes
- Identification of topics where stronger interactions between the nowcasting and NWP communities should be fostered
- Ways to assess and evaluate the potential of mesoscale NWP models for nowcasting purposes
- Discussion on possible follow-up actions and experiments

A tentative agenda is laid out by the organizing committee in which the session topics and keynote speakers are identified (see the following pages). In each of the five sessions, presentations by the invited participants will be selected. If you wish to give a presentation, please submit your abstract as an email attachment to Jenny Sun at the address workshop@ucar.edu. The deadline for the submission of the abstract is 9 September 2011.
