    A model for estimating 1-min rainfall rates at a location for which routine climatic data are available was used to produce this atlas. Even though data were available for 483 locations, considerable subjectivity and smoothing of the analyses was required because of the low station-density in most areas. Southern Hemisphere analyses of rainfall rates equalled of exceeded 0.01, 0.05, 0.10, 0.50, and 1.0 percent of the time are presented for four mid-season months. Analyses of the highest rainfall rates for the same frequencies of occurrence regardless of the month in which they occur and companion analyses of the month in which the highest rate occurs are also presented.
