Summertime diurnal precipitation patterns for Phoenix, Arizona are analyzed for the period 1954 through 1985. Although the mean precipitation amounts and frequencies for the entire summer monsoon season have not shown any significant effects from the rapidly developing urban heat island, diurnal patterns have displayed substantial changes in the recent period of explosive population growth. During the most recent 16 years, late afternoon and evening storms have become more frequent and produce greater rainfall totals. Sharp declines are noted in the frequency of rain events between midnight and noon; especially large drops occur in the rainfall amounts between 9.00 and 12.00 MST. These findings appear to be consistent with several mechanisms proposed to explain the unusual diurnal character of the summertime rainfall in the Phoenix, Arizona area.
