For reference: Enhanced Fujita Scale classifies tornadoes into the following categories:
A microburst is a convective downdraft with an affected outflow area of less than 2 1/2 miles wide and peak winds lasting less than 5 minutes. Microbursts may induce dangerous horizontal and vertical wind shears, which can adversely affect aircraft performance and cause property damage. Straight-line winds are generally any wind that is not associated with rotation, used mainly to differentiate them from tornadic winds. |
