Where no number appears, the storm was studied by the Hydrometeorological Branch, National Weather Service as part of this or other hydrometeorological investigations. o This center is part of the Cherry Creek, CO storm (47) and was contained in MR 3-28A. For the purposes of this study a separate analysis was made (see Appendix) . the region for which there is limited data. Justification for such transposition is based on the existence of meteorological homogeneity of storm conditions between the actual and transposed locations. Homogeneity implies that the storm mechanisms that operate in the regions of storm occurrence are comparable to the storm mechanisms that occur throughout the portions of the region where there is a paucity of large storm rainfall amounts. Further discussion of storm transposition is given in chapter 8. 2.3 Important Storms From the list of major storms in table 2.1, a preliminary selection was made of the storms believed to be most important for the purpose of estimating PMP within the CD-I03 region. The selection was based on the examination of DAD data and storm location, as well as from experience gained in previous studies. Forty- three storms were selected as important storms to consider when determining PMP over the CD-I03 region. These storms are listed in table 2.2 and depth-area- duration data for most of the general storms in this list are given in Appendix B. The other storms were studied less intensively, primarily to define the regions of meteorological homogeneity. These storms are of lesser importance in determining the controlling level of PMP in the study region. The storm 15
