Book excerpt: Preliminary models are developed relating 1-minute precipitation rates to commonly available monthly climatology. Regression equations are provided for precipitation rates equal or exceeded 0.1, 0.5, 1.0, and 2.0 percent of the time during a month. Models are developed using a precipitation index (monthly precipitation/number of days per month with precipitation) alone, and the index and monthly mean temperature as estimators. Separate models are presented for tropical and extratropical regimes, with some gain in precision of estimate offset by loss of confidence due to the small amount of data and fewer locations in each subset. The models and regressions are regarded as preliminary, since only 36 months of data are available for four stations. Data for additional stations are being prepared and will be used to refine these models. (Author).
