Severe Weather Climatology in the Midwest and Arboriculture    (View PDF)

Richard G. Semonin

Abstract: The temporal and spatial distribution of severe weather events which impact on trees is presented. Severe weather is defined to include wind, hail, glaze, lightning, drought, and freezing temperatures. These weather phenomena are divided into those which affect the tree structure by immediate impact and those which affect tree growth as a result of long-time exposure to abnormal weather. The probability of occurrence of these events is presented with the purpose of eventual modification, by use of such information, of currently defined hardiness zones.
