Spatial and Temporal Correlation of Precipitation in Illinois

摘要

Analyses were made of the correlation patterns of annual, seasonal, monthly, storm, and partial storm precipitation in Illinois, with major emphasis on the warm season months of May-September when convective rainfall dominates and spatial variability maximizes. Data were from the climatic network of the National Weather Service in the annual analyses, and that from dense raingage networks of the State Water Survey in the seasonal, monthly, and storm analyses. Results provide knowledge and basic information concerning the spatial and temporal distribution characteristics of precipitation. This is needed in various endeavors, such as hydrologic studies, weather modification experiments, and agricultural research.
