Fujita, T., 1981: Tornadoes and
downbursts in the context of generalized planetary scales.
These include but are not limited to the inability to fully model swirling flow impacts on structures (tornadoes) and some types of gust fronts (
downbursts); the Reynolds number limitations in accurate modeling wind flows over curved surfaces or flows inside buildings such as natural ventilation or diffusion of pollutants within a partially open enclosure; and the inability to model wind flows in atmospheric boundary layers with various stability conditions [3].
Forest disturbance in hurricane-related
downbursts in the Appalachian Mountains of North Carolina.
Despite the fact that most weather-related failures of high-voltage transmission lines (HVTLs) are attributed to
downbursts accompanied by heavy rainfall, research works are mainly focused on the behavior of the transmission towerline structures under dry
downburst winds.
There are several types of damaging wind storms, including tornadoes,
downbursts, microbursts, gust fronts, derechos and haboobs.
Downbursts or microbursts may produce wind shear--a variation in wind
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.
The study finds that
downbursts are dangerous to navigation.
It has vertical and horizontal components and is associated with the microbursts and
downbursts generated by thunderstorms and/or frontal activity.
Downbursts, 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.
