The atmospheric water balance computation is used for two distinctly different kinds of applications in this paper. First, the atmospheric water balance is used to infer the exchange of water at the earth's surface over the upper Colorado River Basin. Thirteen winter seasons (1957-1969) were studied, twelve-hourly computations were accumulated from November 1, through April 30 and the resulting seasonal accumulation of water was correlated to the succeeding twelve months discharge from the basin. The correlation between runoff and accumulation is r=0.54. The first seven years show a remarkably good correlation r=0.82. The final six years contain most of the scatter r=0.34. Recent evidence of systematic errors in the measurement of humidity are presented as a possible cause of this deterioration in correlation. The second application of the water balance technique was centered on the study of the precipitation mechanisms within large extratropical cyclone storm systems. (Author)
