Depth-Duration-Frequency Tables The following tables provide sectional mean frequency distributions for storm periods of 5 minutes to 10 days and recurrence intervals of 2 months to 100 years for Michigan. Data provided in the tables is from the Rainfall Frequency Atlas of the Midwest-Bulletin 71 by Huff and Angel, 1992. Project sponsored by the Midwestern Climate Center, Climate Analysis Center, NWS, and NOAA and Illinois State Water Survey. |
