✦ Synopsis


A climatological-cartographic study of nine years of crop-hail insurance data in Saskatchewan shows that a high proportion of total damages is done by storms which leave long, narrow tracks or swaths of hail at the ground. These individual hailstorms are long lived. At least 76 swaths 150 km or more in length occurred during the nine summers, indicating storm lifetimes of at least 3 h. More than half of these travelling thunderstorms persisted for 5 h or more, a few for as long as 8 to I0 h. Such longevity may permit improved forecasting and warning of the hail hazard from 50-60% of these storms.
