Forecasters use factors like instability and dry air aloft to assess the possibility of damaging downbursts
Typically a derecho contains multiple microbursts, downbursts
The study finds that downbursts
are dangerous to navigation.
A bizarre wind - perhaps a storm-related phenomenon called a downburst
- came out of nowhere Wednesday and briefly whipped through an interior courtyard garden at South Eugene High School, lifting a wooden bench into the air, bending a metal awning and sending students, a teacher and a Register-Guard reporter there on an unrelated assignment diving for cover.
And Colin Montgomerie's hopes disappeared below the waves in the gale-force downbursts
of wind up to 160 km/h were recorded in Leon County during the hurricane (Clark 1986) and tropical storm force winds lasted for [approximately]8 h.
Notes from early European travelers give the impression that wind (in the form of downbursts
, tornados, and hurricanes) and fire were the most common disturbances affecting presettlement forests, often working in concert (Harris 1805, Linn 1883, Jordan 1901, Mahr 1953, Wallace 1965).
1981: Tornadoes and downbursts
in the context of generalized planetary scales.
In this article we'll look at windshear from dramatic outflow winds from a storm cell close to the ground, commonly called downbursts
and microbursts historically have had their greatest impact on aviation during the approach and landing phases of flight.
- out-rushing air from thunderstorms that slam into the ground and can exceed 100 mph - can do plenty of damage.
Wind in the BWCAW may blow down individual large trees or level whole stands (rotation period [is greater than]1000 years) during summer thunderstorm downbursts
