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.
