Abstract : Excellent data were obtained on a variety of weather situations ranging from snowstorms in March to hail and thunderstorms in May. Signal intensity contours on both radars, RHI photographs, R-meter measurements and radiosonde soundings were made. Work was resumed on designing and building a sweep integrater for use with short pulse on the AN/CPS-9 radar. It is probable that frequency modulation rather than amplitude modulation will be employed. A tippingbucket rain gauge was built to operate on the outflow of the Hudson-Jardi gauge and thus monitor its operation. The rainfall data were greatly improved by this addition. The data reduction program and the analysis of storm structure are progressing satisfactorily. The computations on modification of fallout patterns by rain were slowed down by computer and program failures. (Author)
