A downdraft is a small-scale column of air that rapidly sinks toward the ground. A macroburst is an outward burst of strong winds at or near the surface with horizontal dimensions larger than 4 km (2.5 mi) and occurs when a strong downdraft reaches the surface.
Apr 26, 2015 · A downburst is an area of strong, downward moving air associated with a downdraft from a thunderstorm. As the downdraft impacts the ground, the air is forced outwards in all directions while it...
Updraft and downdraft, in meteorology, upward-moving and downward-moving air currents, respectively, that are due to several causes. Local daytime heating of the ground causes surface air to become much warmer than the air above, and, because warmer air is less dense, it rises and is replaced by.

A microburst is a localized column of sinking air (downdraft) within a thunderstorm and is usually less than or equal to 2.5 miles in diameter. Microbursts can cause extensive damage at the surface, and in some instances, can be life-threatening.

May 29, 2006 · Downbursts are powerful winds that descend from a thunderstorm and spread out quickly once they hit the ground. These winds can easily cause damage similar to that of a EF0 (65-85mph winds) or even EF1 (86-110mph winds) tornado, and are sometimes misinterpreted as tornadoes.

In meteorology, the downburst is defined by Fujita (1985) and Wakimoto (1985) is a strong downdraft that causes an outflow of damaging winds at or near the surface. Downbursts may be categorized according to scale into macrobursts and microbursts (Wakimoto1985).
A downburst is created by a column of sinking air that after hitting the surface spreads out in all directions and is capable of producing damaging straight-line winds of over 240 km/h (150 mph), often producing damage similar to, but distinguishable from, that caused by tornadoes. [1]
Sep 4, 2023 · Downbursts are an area of powerful winds produced by a storm with strong downward-moving air, known as a downdraft. Downbursts smash into the ground and radiate outward. Wind speeds when a...
Thunderstorm - Updrafts, Downdrafts, Air Masses: The motion of a thunderstorm across the land is determined primarily by the interactions of its updrafts and downdrafts with steering winds in the middle layers of the atmosphere in which the storm develops.
