在40°c平方英里的范围内，已经建立了强风暴的时间分布关系，并以概率形式呈现，以提供风暴间变率的定量信息，并为研究结果的各种应用提供平均和极端关系。研究发现，将暴雨降雨量的%与总暴雨时间的%联系起来，并根据降雨量最大的四分位数对数据进行分组，可以最好地表示这种关系。当使用上述分析技术时，平均降雨量、风暴持续时间和其他风暴因素的个别影响很小且不稳定。盆地面积对时间分布的影响较小，但具有一致性。推导出的关系适用于中西部和其他类似气候和地形的地区。它们可以与已公布的空间分布信息和其他风暴参数相结合，构建用于水文应用的风暴模型。
Time distribution relations have been developed for heavy storms on areas ranging up to 40C square miles and presented in probability terms to provide quantitative information on interstorm variability and to provide average and extreme relations for various applications of the findings. It was found that the relations could be represented best by relating % of storm rainfall to % of total storm time and grouping the data according to the quartile in which rainfall was heaviest. The individual effects of mean rainfall, storm duration, and other storm factors were small and erratic in behavior when the foregoing analytical technique was used. Basin area had a small but consistent effect upon the time distribution. The derived relations are applicable to the Midwest and other areas of similar climate and topography. They can be used in conjunction with published information on spatial distributions and other storm parameters to construct storm models for hydrologic applications.
