Aerial photographs of crop-hail damage areas have revealed a smaller-scale feature of damage patterns than has previously been reported. These features, called “hailstripes,” are long, narrow (15–30 m width) stripes of alternating light and heavy damage. These are believed to be caused by a combination of strong wind and “hailstrands,” long string-like substructures of the hailshaft.

The characteristics of commonly used surface hail instruments are reviewed and instruments evaluated. The instruments evaluated have been classified into two major categories: integrating and recording. The integrating sensors are relatively inexpensive and provide certain useful hail data. The recording sensors are much more expensive but provide more useful data including time of hail. The review includes the principles of operation, types of data obtained, operational advantages and disadvantages, and approximate cost of each type of instrument.
