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 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.
