The microbursts of 22 June 1982 in JAWS

Abstract

The microburst outflows can be classified into three types: isolated, generally symmetric outflows; outflows embedded in strong low-level environmental flow which reveal their symmetric diverging outflow structure only when the mean flow is eliminated; and the microburst line. Some of the microbursts decayed by weakening; others grew to larger-scale, less intense outflows. It is concluded that the microbursts on this day were predominantly driven by microphysical and related thermodynamic effects due to processes of precipitation loading and water phase change. -from Author
