For reference:
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/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.
