Rainfall Climatology of the NWSFO Memphis County Warning Area

摘要

Quantitative precipitation forecasts (OPFs) will be issued in a daily basis, andnormally will include four six-hour forecasts of areally averaged rainfall over local river basins. River Forecast Centers (RFCs) will routinely include QPFs in their calculations of expected river stages, making QPFs a critical part of the prediction of floods and for the protection of life and property. Some important aspects of the QPF forecasting program involve knowledge of the topography, river basins, normal rainfall patterns, rainfall frequency, and synoptic conditions associated with heavy rain events for the local area of responsibility. The purpose of this paper is to provide a complete rainfall climatology for the Memphis CWA, addressing the important aspects of QPF forecasting which will serve as guidance of the quantitative precipitation forecaster.
