A MODEL FOR PREDICTING PRECIPITATION AMOUNTS IN SEATTLE AND WESTERN WASHINGTON
Abstract
A method is devised for making quantitative predictions of precipitation amount for the Seattle and Western Washington areas. In developing the method the following conclusions were reached: (1) Joint Numerical Weather Prediction vertical velocities are not well related to precipitation amounts at Seattle; (2) apparent temperature advection measured from vertical wind shear can be used as a good measure of vertical velocity; (3) use of the resulting vertical velocity, with the water content and degree of saturation of theAIR, GIVES REASONABLE ESTIMATES OF THE AMOUNT OF PRECIPITATION FOR Western Washington; and (4) consideration of wind direction at 10,000 ft and evaporation results in improved estimates of the amount of precipitation.
