Hourly and Daily Precipitation Frequencies for the United States.
Abstract
This report presents daily and hourly precipitation frequencies for an extensive network of stations throughout the United States, from special summaries of observations obtained over the decade 1951-1960. When data are in format of cumulative percent frequency per precipitation rate, the daily and hourly distributions each form a fairly regular progression, per P/D or P/H, respectively (P= total precipitation, D= days, H = hours). The resultant models, in the form of succinct tables, graphs, or computer programs, provide a ready means for recovering the original observations, or estimating any selected precipitation rate for a wide spectrum of precipitation regimes in the United States, or Elsewhere. The models, which serve as a check on data errors, or weather modification, also indicate to the engineer preferred areas testing particular equipment . The methodology for the comparison among stations (or countries) of the actual short-term precipitation distributions, given only routine climatic data, should be highly useful for assessing more accurately a host of factors, as: soil moisture, trafficability, water supply, crop yields, or possible malfunction of electronic equipment. The greatest advantage of the result is that they may be utilized for estimating short-term precipitation in data sparse localities.
