Subject: The Earth A strong downdraft (downburst) greater than 4 km wide that can occur beneath thunderstorms. A downburst less than 4 km across is called a microburst.[ Pics List
A larger downburst affecting an area greater than 2.5 km in diameter.
A downburst affecting an area greater than 4 kilometres across and having damaging winds. Macrobursts are generally longer-lived than the smaller microbursts. Macrobursts have been documented to 'wrap-up' into weak tornadoes, however these would be classified as gustnadoes as they are not directly associated with storm-scale rotation. See also microburst.
Large downbursts with a 2.5 mi or greater outflow diameter and damaging winds lasting 5 to 20 minutes.
a large downburst within a 2.5 mile or larger outflow diameter and damaging winds lasting five to twenty-five minutes.
A large downburst affecting an area more than 4 kilometers (about 2.5 miles) across with damaging winds lasting from 5 to 20 minutes. May reach tornado intensity.
A strong down draft (down burst) greater than 4 km wide that can occur beneath a thunderstorm. A down burst less than 4 km is called a "microburst". Thunderstorm winds that exceed 58 miles per hour are a feature of a "Severe Thunderstorm".
A harsh wind, covering more than 2.5 miles, that blasts downward from a thunderstorm.
A large downdraft of air with an outflow diameter of 2.5 miles or greater and damaging winds lasting from 5 to 20 minutes. May reach tornado intensity.
A downburst more than 2 1/2 miles in diameter and lasting 5 to 20 minutes.
Large thunderstorm downbursts with a 2.5 mile diameter or greater outflow of damaging winds lasting 5 to 20 minutes.
downburst on the misoscale. Bow echoes are often associated with macrobursts. See also microburst.
A large downburst with an outflow diameter of 2.5 miles (4 kilometers) or larger and damaging winds.
