DIAGNOSIS AND PREDICTION OF PRECIPITATION IN REGIONS OF COMPLEX TERRAIN. FINAL REPORT

This research has attempted to determine the distribution of precipitation in the complex terrain of Washington State. The first part of this report examines the precipitation distribution for various large scale wind directions. It is found that there are meaningful shifts in the precipitation pattern as the large scale wind changes direction and that knowledge of this behavior can be useful for operational applications. The second section presents a simple numerical model of precipitation in complex terrain. Although the results are not perfect by any means, they can usefully indicate the variation of precipitation in the mountains. However, such a model requires at least a minicomuter to run it.
