Abstract |
Annual, monthly, and hourly rainfall data for Hilo, Hawaii, are plotted and analyzed as a preliminary phase of the study of space-time variations in high intensity rainfall. A summary of the Hilo climate is provided. Annual rainfall amounts are highly variable, while the annual rainfall frequency remains relatively constant at about 33%. Monthly rainfall and maximum 24-hour rainfall amounts are displayed in a monthly rainfall expectancy graph. Hourly rainfall amounts are divided into four intensity categories: 0.01-0.24, 0.25-0.49, 0.50-0.99, and = or > 1.00 inches per clock hour. The percentage distribution of annual and monthly rainfall amounts and frequencies by rainfall intensity category are plotted and discussed. Hourly data are displayed in a series of monthly diurnal distributions by rainfall intensity category. (Author) |
