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.
