A microburst is a powerful downdraft that descend through a thunderstorm. When they reach the ground they produce damaging winds that in some cases can reach as high as 150 mph.
A microburst is different from a tornado in that:
Air travels downwards and outwards in a microburst, while it travels inwards and upwards in a tornado.
A microburst produces straight-line winds while a tornado produces circular winds.
Downbursts, are powerful downdrafts or downward movements of air the occur during thunderstorms. In such an event, rain-cooled air starts to descend rapidly. When the downburst reaches the ground the air moves outward at high speeds, often causing damage. Most downbursts are called microbursts as they affect a fairly small area. Downbursts affecting an area more than 2.5 miles across are called macrobursts.
A microburst is a powerful downdraft, or downward moving air current that can occur during a thunderstorm as rain cools the air. When the microburst reaches the ground it moves outward, creating very strong winds. Microbursts can be dangerous, especially to aircraft that are taking off and landing.
An intense, localized downdraft of air that spreads on the ground, causing rapid changes in wind direction and speed. Microbursts are a common cause of wind damage in thunderstorms
It is a small scale downburst caused by an intense downdraft
A macroburst and a microburst are similar events, but a macroburst exceeds 2.5 miles in diameter.
A microburst is a huge downdraft that can happen during strong thunderstorms. Sometimes, they are confused with tornadoes because of their shape and how they touch the ground at some point. After damage is surveyed, it can be seen from an areal view how a tornado's damage track turns and all of the debris are twisted while a microburst knocks down trees and never twists anything up.

The damage from a microburst appears to radiate out from the center while tornado damage occurs along the path that the tornado took. In a microburst trees fall or are bent outwards, with trees that neighbor each other generally falling in the same direction. In a tornado downed trees to not have the same order, and fall in multiple directions. Those left leaning may hint towards an inward or rotating flow. Some tornadoes have roughly crescent shaped areas of more severe damage, indicating a multivortex structure.
Microbursts produce very strong winds sometimes to over 130 mph, which is stronger than many tornadoes and hurricanes. Such winds can easily cause injury through knocking people down or with wind blown debris.

A macroburst and a microburst are similar events, but a macroburst exceeds 2.5 miles in diameter.
A tornado does not produce a microburst, they are two different things. A microburst is a powerful downdraft in a thunderstorm that spreads out when it hits the ground, producing very strong, damaging winds that can equal those of a tornado.
The strong winds of a microburst may spray or splash some water out of a swimming pool, but other than that, no. Unlike a tornado, air in a microburst does not travel upwards.
The word is Microburst!!
A tornado is a violently rotating column of air. Air in and around a tornado moves inward and upward in a spiral pattern. Unlike in a microburst, tornado damage usually follows a discrete path. A microburst is a sudden and intense downdraft within a severe thunderstorm that produces powerful winds. Unlike a tornado the winds in a microburst travel downward and outward and do not rotate.

The deadliest microburst appears to have ocurred on July 9, 1982 in Kenner Lousiana. Pan Am Flight 759 was taking off from New Orleans International Airport when it was caught in the microburst and crashed, killing all 145 people on board and another 8 people on the ground for a total death toll of 153.

One prefix for smaller is micro- For example: microwave, microburst
Microbursts are spawned by heavy to severe thunderstorms (if the microburst results in strong enough winds, the thunderstorm will become severe by definition).
