Current rainfall totals brooks oregon9/19/2023 Finally, a discussion of the results and how they impact the findings of BS00 is presented in section 6. The diurnal cycle of heavy rainfall is presented in section 5. In sections 3 and 4, the monthly frequencies and distributions of hourly precipitation are examined, and the estimates of extreme rainfall rates from BS00 are reevaluated using high-resolution data. We first describe the datasets used in this study and compare them to the HPD in section 2. The present study seeks to revisit the climatology of heavy and extreme rainfall in the United States developed by BS00 using high-resolution precipitation analyses that incorporate rainfall estimates from the WSR-88Ds. It was suggested that with the advent of the Weather Surveillance Radar-1988 Doppler (WSR-88D) network a climatology based on radar-estimated precipitation could be constructed, allowing for a refinement of the results presented in BS00. This limitation is especially apparent when considering extreme precipitation events that are more likely to be undersampled, such as the 9 June 1972 Rapid City, South Dakota, flood ( Maddox et al. The spatial and temporal information provided by this study serves as a valuable guide to forecasters on the flash flooding threat however, the authors recognize the limitations of using data from the HPD, namely the coarse station spacing (approximately 50 km on average). BS00 utilized the relatively long record length of the Hourly Precipitation Dataset (HPD) to construct a climatology of heavy rainfall events at 1–3-h durations, commenting on observed frequencies and estimating the frequencies of extreme events. Prior to the study by Brooks and Stensrud (2000, hereafter BS00) there had been little research on heavy rainfall at hourly time scales in the United States, let alone a climatology of such events.
