This document describes statistical characteristics of microbursts that occurred in the Denver area during the summers of 1982 and 1984. The Joint Airport Weather Studies (JAWS) Project, conducted between 15 May and 13 August 1982, is the primary data source for this report, and radar data from the Classify, Locate and Avoid Wind Shear (CLAWS) Project are also included for microburst lines and low-reflectivity microbursts. All surface mesonet data come from the JAWS Project. This report describes the statistical characteristics of the JAWS and CLAWS data that have been analyzed to date and is intended to be used as a working document. It is primarily a compendium of several different sources brought together in a single document....
