PREDICTION OF PRECIPITATION IN WESTERN WASHINGTON STATE. FINAL REPORT

This research adapted an orographic precipitation model developed during a previous WSDOT project (Report No. WA-RD-91.1) to run efficiently on an operational basis on a 386 personal computer, and made numerous model improvements. The precipitation model is being used operationally at the Northwest Avalanche Center in Seattle. Although the model is two-dimensional and employs simple precipitation parameterizations, it reproduced observed precipitation for two case studies remarkably well. The model should provide forecasters with useful guidance, especially during flow patterns that exhibit relatively two-dimensional characteristics.
