Scientific and Technical Planning Workshop for the PACJET Experiment
9:00 AM Thursday July 13th to 3:30 PM Friday July 14th, 2000
| |||
Goals |
| ||
Outcome | A list of key technologies and concepts that could be tested during PACJET, and the beginnings of an operations plan. | ||
Background | This Workshop is envisioned as a step toward improving U. S. West Coast
short-term weather prediction by exploring new observing
and modeling technologies.
With the PACJET field phase approaching (5 January to 18 February 2001) it is timely to take the current plan to the next level of maturity and to fully explore how PACJET can be most effective in terms of both scientific research and operational applications. This meeting will review the current status of the experiment, new observing technologies, plans for real-time modeling efforts, and pathways for data dissemination and user assessments. This Workshop builds on forecaster and forecast-user input from an earlier PACJET workshop held in Monterey in September 1999, and on developments since then, such as the inclusion of PACJET in the U. S. Weather Research Program's data assimilation implementation plan. | ||

Tentative agenda | |||
13 July: | Meeting starts at 9:00 AM. Sessions devoted to goals 1 and 2. Consider how to coordinate efforts in core subject areas of physical process studies, observing systems, numerical modeling, and operational applications. | ||
14 July: | Detailed discussions on: strategies for the aircraft and ship, what ground-based facilities are needed and where to deploy them, overall logistics of the program, plans for two operations centers (Monterey-primary and Seattle-secondary), and optimizing operational use and assessments. Develop an outline for an operations plan. | ||
Meeting format | Oral presentations, discussion, and formulation of next steps. | ||

Lodging | The Broker Inn in Boulder has set aside 10 non-smoking rooms at the
government lodging per diem rate of $90.00 per night. This rate is
available for 12 and 13 July (2 nights). This is an excellent rate
during Boulder's high tourist season. Please make reservations by
Monday June 12th. After that, the rooms will be released to the public.
To reserve your room please call 303-444-3330; ask for reservations and indicate you are with the PACJET/ NOAA workshop. The Broker Inn is at 30th and Baseline in Boulder, which is about a 15 minute walk from NOAA, and has set aside a block of 10 rooms (all non-smoking) for the PACJET Workshop. | ||

PACJET Overview |
The Pacific Landfalling Jets experiment (PACJET)
and a Long-term Effort to Improve 0-24 h West Coast Forecasts
27 January 2000 1. Overarching goal To develop and test methods to improve short-term (0-24 h) forecasts of damaging weather on the U. S. West Coast in landfalling winter storms emerging from the data sparse Pacific Ocean. PACJET is designed to be a next step toward attaining this goal. It is envisioned as part of a long-term effort that combines analysis, a series of focused field experiments, development of new products and tools for operational forecasting, and exploration of physical processes that contribute to the linkage between seasonal-to-interannual climate variability (e.g., ENSO) and extreme coastal weather events. 2. Time and location of PACJET Roughly 5 January 2001 to 18 February 2001 From 300 km inland to 1000 km offshore of the U.S. West Coast from Southern California to Washington State. This covers the area between the coast and the central Pacific domain sampled by the Winter Storm Reconnaissance program. 3. Background PACJET addresses short-term weather prediction along the US West Coast during winter, focusing on quantitative precipitation forecasting. It builds on experience gained from CALJET, an earlier west coast experiment performed during the strong El Ni�o of 1997/98. For details on CALJET see http://www7.etl.noaa.gov/programs/CALJET/index.html. CALJET aided flood forecasting, studied the utility of new observations, and explored the relationship between El Ni�o and extreme coastal storms. PACJET expands the area covered by CALJET and targets the coastal zone, which is an area of extreme societal vulnerability for which forecasts are typically less accurate than over the rest of the continent. PACJET directly links core USWRP objectives on quantitative precipitation forecasting (QPF) and optimal observing systems to this difficult but important problem. The strategy is based on applying research techniques and technology development over several years to address specific forecast problems, such as flood warnings, high wind warnings, and marine warnings. An ongoing series of focused field experiments is envisioned over the coming years to test new instruments, data assimilation techniques and operational tools that emerge from analysis of the previous experiments, and to develop a strategy to anticipate the nature of extreme weather events linked to climate variability (e.g., ENSO). |
