Abstract

A quantitative method of predicting precipitation due to large-scale vertical motions is described. A two-level prediction model is applied at the 1000- and 500-millibar pressure levels. Solutions are obtained by graphical procedure which enables one to obtain a 24-hour forecast in about two hours for an area comparable to the size of the North American continent. Tests on ten cases of major cyclone developments show some success.
