Results of Hail Suppression Efforts in North Dakota as Shown by Crop Hail Insurance Data

Abstract

An examination of crop-hail insurance data as a tool to evaluate hail suppression efforts in western North Dakota is presented. Six western North Dakota county (Target area) data are compared to twelve eastern Montana county (control area) data. Target/control seed years versus non-seed years wheat yields, insurance liability, and loss cost values are compared. The data analysis using double ratios and target/control comparisons suggests that a 17 to 41% lower hail insurance loss experience is found for the areas participating in the North Dakota cloud seeding project. The data suggest that the direction of the hail loss experience supports the goals of the North Dakota project, but cannot be used to establish unequivocally that the direction and its magnitude are the result of the cloud seeding efforts.
