The Effect of Hail Suppression Operations
on Precipitation in Alberta, Canada

Hailstorms pose a serious threat to agriculture and property in the province of Alberta, Canada.
Annual losses to agriculture range from CAD$50 to $100 Million.
From 1988 to 1998, insurance losses due to hail in Alberta exceeded CAD$1 Billion.
The new Alberta Hail Suppression Project was initiated in 1996 as a result of the increased frequency of damaging hailstorms in Alberta, compounded by an increasing population inside the area of high storm frequency around Calgary. (image right of project area)
It is the first project of its kind in the world to be entirely funded by private insurance companies with the sole objective of reducing the damage to property by hail.
This analysis of the effect of the cloud-seeding on the rainfall is motivated by allegations from some farmers during the drought of 2001 and 2002 that hail suppression operations might reduce rainfall.
