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.
