Forest disturbance in hurricane-related downbursts

are responsible for most of the "straightline wind" damage reports, but also can have major impacts at airfields.
There are several types of damaging wind storms, including tornadoes, downbursts
, microbursts, gust fronts, derechos and haboobs.
84) Microbursts are small, concentrated downbursts
Across eastern North America, winds from tornadoes and downbursts
(strong downdrafts that cause damaging winds) disturb thousands of forested acres each year, devastating both conservation areas and timberlands according to a 2000 study.
Damage from downbursts
can be so severe that it is mistaken for tornado damage.
It has vertical and horizontal components and is associated with the microbursts and downbursts
generated by thunderstorms and/or frontal activity.
, which can bring gusts of up to 50 mph, can occur when a nearby thunderstorm dies down.
Downdrafts can be damaging; their extreme form, downbursts
or wind sheer, can be as locally destructive as tornadoes and have caused airplane crashes.
Other thunderstorms during the night created strong downbursts
leading to damaging winds in the Quad City area and in certain suburbs of Chicago.
The studies did not include episodes of turbulence associated with intense convectively-induced turbulence such as that produced by strong outflow or downbursts
39 Generally cumulonimbus (heaped dark clouds) are the most dangerous clouds associated with hail, lightning, tornadoes, downdraughts, downbursts
and flash flooding.
