Interpretive Summary: A useful method for describing rainfall intensities for an area uses a set of curves called "Huff curves". Several factors are important in developing a set of these curves for an area, such as the total depth of a storm, the number of storms, season, etc. A method is needed to compare sets of curves so that one can use the curves with confidence for a practical application. The study presents preliminary results on differen methods of comparing curves. The results will be useful for simulation of storms and within-storm rainfall intensities, and for use in weather generators.

Technical Abstract: Huff curves are useful characterizations of rainfall intensities within storms. However, different factors can affect their development, such as sample size, storm size, season of year, etc. A method is needed to compare objectively Huff curves to determine if the final set of curves is reliable for further use, and if results from their use can be compared. Furthermore, these curves, developed from several different rain gages, need to be compared to determine the extent of regionality of the curves. The study presents preliminary results of possible methods of comparing curves. The results are useful for developing reliable set of Huff curves. They will be useful to researchers interested in global change and weather generator development.
