Frequency distributions of heavy rainstorms in Illinois

 
 Volume/Number:  1989  
 Issuing Agency:   
 Description:  This publication represents a condensed version of an extensive report on the distributions of heavy rainstorms in Illinois, based on data for 61 precipitation stations operated during 1901-1983. Shown are annual frequency distributions of point rainfall for periods ranging from 5 minutes to 10 days and for recurrence intervals varying from 2 months to 100 years. Results are presented in two forms: mean relations for ten regions of approximately homogeneous precipitation climate, and statewide isohyetal maps based on the 61-station data The report also discusses the results of a special investigation pertaining to Chicago and the surrounding six counties subject to urban influences on the precipitation distribution. The final section of the report provides information on the urban influences on the two Illinois counties adjacent to St. Louis.
