The relation between Arizona's summer rains and the amount of water vapor in the air over Arizona was examined. It was found that the occurrence of rain was primarily determined by the moisture content of the air over the state, defined in this study by the amount of precipitable water at Phoenix. The effects of vertical wind shear and stability on the occurrence of rain were examined, but could not be precisely determined and are probably small as compared with the effects of precipitable water. Precipitation efficiency was found to vary directly with variations in the amount of precipitable water, but could be explained by changes in the evaporation of raindrops between cloud bases and ground in environments of differing precipitable water contents.Type
