THE HAIL-THUNDERSTORM RATIO1

Areal Frequencies of Hail and Thunderstorm Days in Illinois

Hail and thunderstorm statistics for the 1951-60 period obtained from 119 U.S. Weather Bureau stations in Illinois were conlbined n-ith crop-hail insurance data for this same period for performing a detailed climatological investigation of the frequencies of hail days and thunderstorm days in Illinois. In the crop-growing season thunderstorms occur on 1 out of every 2 days on the average and ha...

Hail suppression and society.

An interdisciplinary assessment of hail suppression in the past, present, and future has shown it to be currently scientifically uncertain but a potentially beneficial future technology. An established suppression technology would be widely adopted in the Great Plains, providing benefits to agriculture and secondarily to the American consumer. Development of a reliable technology will require a...

Evaluation of Alberta Hail Growth Model Using Severe Hail Proximity Soundings from the United States

A one-dimensional, coupled hail and cloud model (HAILCAST) is tested to assess its ability to predict hail size. The model employs an ensemble approach when forecasting maximum hail size, uses a sounding as input, and can be run in seconds on an operational workstation. The model was originally developed in South Africa and then improved upon in Canada, using high quality hail verification data...
