Investigation of Cloud and Precipitation Physics by Radar

Significant developments in instrumentation directed toward the optimum use of radar in investigations of cloud and precipitation physics were accomplished. A new technique in film display of radar information provides intensity maps in conformal map form. This display, called AZLOR, compliments the standard PPI display with detail and conformity to the true pattern in small areas. The technique of pulse compression was devised and employed in selected weather situations. A body of microwave attenuation statistics was accumulated from AZLOR records of severe storms. Data were accumulated and analyzed to relate precipitation seen by radar to cloud seen by photography. Radio-located lightning flashes were related to precipitation by radar. A new technique was explored to extrapolate radar precipitation measurements to the surface for comparison with rain gauges.
