LCL height also factors in downburst and microburst activity. Downburst winds can produce numerous hazards to landscapes experiencing thunderstorms. Derechos are longer, usually stronger, forms of downburst winds characterized by straight-lined windstorms. A macroburst, normally associated with squall lines, is a strong downburst larger than . The formation of a downburst starts with hail or large raindrops falling through drier air. Automobiles can be displaced by the force exerted by downburst winds. On unusual occasions there could be a weak downburst and small hail. In some situations severe downburst winds may push automobiles around, especially high-profile vehicles. Fujita's downburst theory was not immediately accepted by the aviation meteorology community. Downburst damage continued to SW of Asheboro. This phenomenon is known as a downburst. Initial reports indicated that the collapse was the result of a downburst. VIL can be used to estimate the potential for downburst, too. They go through three stages in their cycle&colon; the downburst, outburst, and cushion stages. Figure 3.22 from this reference shows the presence of a rotor outside a downburst.
