A microburst is a small downburst of wind, with outbursts of damaging winds extending 2.5 miles or less. (despite it's small horizontal scale, a microburst can induce wind speeds up to 150 knots or 172.6 miles per hour) Return to your previous position.
A small downburst affecting an area less than 2.5 km in diameter.
A strong localized downdraft (downburst) less than 4 km wide that occurs beneath thunderstorms. A strong downburst greater than 4 km across is called a microburst.
a concentrated wind that blasts down from a shower or thunderstorm
a rapid downdraft that, as it approaches the ground, fans out in all directions
a small, very intense downdraft that descends to the ground resulting in a strong wind divergence
a sudden burst of high wind that is especially dangerous to airplane pilots
a very localized column of sinking air, producing damaging straight-line winds similar to, but distinguishable from tornadoes A tornado is a violent windstorm characterized by a twisting, funnel-shaped cloud
A strong localized down draft (down burst) less than 4 km wide that occurs beneath thunderstorms. A strong down burst greater that 4 km across in called a "macroburst". Thunderstorm winds that meet or exceed 58 miles per hour are a feature of a "Severe Thunderstorm".
A harsh wind that blasts down from a thunderstorm. A microburst lasts for a short amount of time and covers less than 2.5 miles.
A small downdraft of air with an outflow diameter of less than 2.5 miles with the peak winds lasting from 2 to 5 minutes. May affect aircraft performance.
A small downburst, less than 2 1/2 miles in diameter and lasting 2 to 5 minutes.
A strong localized downdraft less than 2.5 miles in diameter from a thunderstorm. Peak gusts last from 2 to 5 minutes.
A small downburst from a thunderstorm with horizontal outflow winds extending 2.5 miles or less. Wind speeds of 50 to 100 mph or greater are possible. Microbursts in Northern Arizona are usually associated with high based (dry) thunderstorms.
A small, very intense downdraft affecting an area of less than 4 kilometers wide. Microbursts are capable of producing winds of more than 100 mph causing significant damage on the ground. They are a serious threat to aviation
an intense downdraft ( downburst) less than 4 km wide (about 2.5 miles) that may occur beneath a thunderstorm
A downburst from a thunderstorm that is confined to a small area.
A strong localized downdraft from a thunderstorm with peak gusts lasting 2 to 5 minutes.
A small, concentrated downburst affecting an area less than 4 kilometers (about 2.5 miles) across. Most microbursts are rather short-lived (5 minutes or so), but on rare occasions they have been known to last up to 6 times that long.
A severe localized wind blasting down from a thunderstorm. It covers an area less than 2.5 miles (4 kilometers) in diameter and is of short duration, usually less than 5 minutes. Related term: downburst
A microburst is a very localized column of sinking air, producing damaging divergent and straight-line winds at the surface that are similar to but distinguishable from tornadoes which generally have convergent damage.
