AB: The Hydrometeorological Design Studies Center of NOAA's National Weather Service recently has made significant changes to their precipitation frequency analysis method and updated their maps for parts of the southwest and east-central U.S. The new method uses statistics called L-moments to select and fit extreme value distributions, as L-moments are less susceptible to outliers in the data. The approach also combines data regionally to determine the shape of the distribution, producing more robust results. In this study, the method is applied to Chinese rain gauge data to create precipitation maps, particularly for 100-year 24-hour precipitation amounts.
