Abstract
Composite synoptic charts are presented which illustrate the large-scale circulation at the surface and aloft over much of the North Pacific Ocean during periods of dry weather on Oahu. Seasonal (fall, winter, and spring) composite charts and pressure-height anomalies associated with dry weather on Oahu are shown for three levels: sea level, 700 mb., and 300 mb. Further stratification is achieved by classifying the dry days, depending upon the presence or absence of trade winds in Hawaii.
