United States Climate Normals, 1971-2000. Monthly Precipitation Probabilities and Quintiles, 1971-2000. Climatography of the United States No. 81. Supplement No. 1

摘要

This Climatography includes selected precipitation probabilities derived from the 1971-2000 normals. Precipitation quintiles, divided into six classes by the five probability levels 0.2, 0.4, 0.6, and 0.8, are also provided. Precipitation probabilities at the 0.1, 0.5, and 0.9 levels are also presented. This publication includes precipitation probabilities and quintiles for first-order stations$ all other stations are available through an accompanying digital data set associated with Climatography of the United States, No. 81. The precipitation probabilities are the monthly precipitation totals that correspond to the indicated probability levels. The probability levels are based on the 1971-2000 historical sequential monthly precipitation. The historical precipitation data are the adjusted values from the monthly normals as presented in Climatography of the United States No. 81.
