USWRP Pacific Northwest: Major Components
• Real-time, operational mesoscale environmental prediction– MM5 atmospheric model– DHSVM distributed hydrological model– Calgrid Air Quality Model– Oregon State Surface Model
• Collection and quality control of regional observations.
• Regional field programs and research efforts to study mesoscale structures (e.g., COAST, IMPROVE)
• Regional research to improve model parameterizations (PBL effort, microphysics)

A Vision of an Integrated Regional Prediction System
Output from the MM5 is now being fed into a number of modeling and diagnostic systems:
• Distributed Hydrological Model for Western Washington
• Calgrid Air Quality Model• Land Surface Model for Surface Temperature
Prediction• Smoke, Ventilation, and Fire Guidance• Transportation Information System

Regional Research Efforts
• IMPROVE: To improve moist physics in mesoscale models using data from the Pacific Northwest. Multi-investigator project. Data from a major field experiment
• PBL Parameterization Project: Evaluation and improvement of MM5 PBL schemes. Sponsored by the Forest Service
• COAST: Two field programs using P3 to study regional mesoscale features

Summary• The NW forecasting and research effort has
tested a regional approach to weather research.• Has resulted in close interactions of
researchers and the user community.• Benefits also include acquisition of non-
traditional funding as well as testing of new approaches to NWP that will be useful in other venues.
• A model for future U.S. weather research should include both national and regional efforts.
