Abstract : During the summer of 1960, a mesometeorological network was established in a 30 x 40 mile area around San Francisco M OUNTAIN NEAR Flagstaff, Arizona. Precipitation measurements were made using 165 small, transparent plastic cups and 165 aluminum-foil hail indicators. Instrument spacing of from one to four miles over most of t e network proved satisfactory. Both the rain gauge and hail indicator provided reliable measurements. The small-cup rain gauges were somewhat more effective in recording rain from a trace through 0.5 or 0.6 inches than standard gauges. Analysis showed that the isohyets of maximum rainfall were elongated in the general direction of the 700 to 500-mb winds. Practically all of the heavy rain storms were accompanied by hail. At least two of the hail areas were observed to be o an elliptical configuration, and at least two were responsible for locally heavy fogs. Coincidence of the axes of maximum daily precipitation and the axes of maximum total precipitation lead one to suspect the existence of preferred storm tracks. (Author)
