A downburst occurs when the downdraft from a storm spreads out horizontally in all directions when it reaches the ground. The wind it creates can be very strong and can cause damage like a tornado. A downburst that is small in size is called a microburst… Derechos are straight-line winds associated with the downburst.

Downburst is the general term for all localized strong wind events that are caused by a strong downdraft within a thunderstorm, while microburst simply refers to an especially small downburst that is less than 4 km across… A typical derecho consists of numerous microbursts, downbursts, and downburst clusters.

That is why on-board weather radar is used to detect the relative speeds of the rain drops at different distances ahead of the plane, to predict where the wind shear is occurring. If a plane enters a downburst it could lose or gain 40 or 50 knots of airspeed within seconds, or fly into air that is descending very quickly.

A microburst is generally an intense down draft while wind shear can occur in any direction. It might be safe to say that a microburst is windshear but not all windshear is a microburst. From your linked pages . A microburst is intense small-scale downdraft produced by a thunderstorm or rain shower. and

These winds along an entire squall line can cause a derecho. Derechos are straight-line winds associated with the downburst. Derechos can be very large and last for a long period of time.

Sometimes the winds push up air above them, forming a shelf cloud or detached roll cloud. A derecho is a widespread, long-lived wind storm that is associated with a band of rapidly moving showers or thunderstorms. A typical derecho consists of numerous microbursts, downbursts, and downburst clusters.

Burst swaths range from about 50 to 150 yards (45 to 140 meters) in length. The damage they produce may resemble that caused by a tornado. A typical derecho consists of numerous downburst clusters ("families of downburst clusters") that are, in turn, composed of many smaller downbursts, microbursts, and burst swaths.

In fact, a downburst that spans a distance less than 2.5 miles in diameter is considered a microburst. (WATCH: Dramatic Microburst Caught on Camera by Australian Farmer)

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. There are two primary types of microbursts: 1) wet microbursts and 2) dry microbursts.

4.5/5 (149 Views . 23 Votes) 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. A microburst is a small concentrated downburst that produces an outward burst of strong winds at or near the surface.

Downbursts. are really nothing more than strong downdrafts. if the diameter of the downdraft is 4 km or less, the downburst is called a microburst. if the diameter of the downdraft is greater than 4 km, the downburst is called a macroburst. downbursts can produce winds comparable to weak tornadoes.
