A downburst is a strong downward movement of rain cooled air that occurs during some thunderstorms. Air reaches the ground and the spreads out. Downbursts produce strong, often damaging winds at ground level. A microburst is a smaller-scale downburst, covering an area of less than 2.5 miles (4 km).

What causes a microburst?
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.
Do downbursts occur in flat areas?
Downbirsts can occur anywhere that there are severe thunderstorms, regardless of terrain.
Where do microbursts usually occur?
Microbursts occur when the evaporation of rain within a thunderstom cools the air, causing it to lose buoyancy. The air then descends rapidly. When it reaches the ground it spreads out, producing strong, sometimes damaging, winds.
Are microbursts stronger than macrobursts?
No. Overall a macroburst is simply larger. Both are capable of producing winds well over 100 mph.
Is a force 12 storm on the beaufort scale a hurricane?
Such winds are considered hurricane force, but other types of windstorms including tornadoes, derechos, and microbursts.
What are down drafts?
Downdrafts are damaging winds on or near the ground. They are called downbursts or microbursts if caused by a thunderstorm which they usually are
Were do microbursts happen?
Microbursts are spawned by heavy to severe thunderstorms (if the microburst results in strong enough winds, the thunderstorm will become severe by definition).

Does down burst turn into thunderstorms?
No, thunderstorms produce downbursts.
What technology is being used to detect microbursts?
The main technology that is being used to detect microbursts is Doppler radar. Another one called LIDAR is also growing in popularity.
What term is used to describe powerful downdrafts that originate in thunderstorms?
microbursts
Do downburst spin in different directions nortern hemisphere then the southern hemisphere?
No. Downbursts generally do not spin.
Do downbursts occur in flat areas?
Downbirsts can occur anywhere that there are severe thunderstorms, regardless of terrain.
Which occurs more microburst or tornado?
Microbursts are more common. Most wind damage from thunderstorms comes from microbursts, and damaging wind is the most common type of severe weather report. By contrast only about 10% of severe thunderstorms produce tornadoes.
Does downbursts strong winds that rise into a thunder storm cloud?
No. A downburst produces winds that violently descend from a thunderstorm.
How strong can thunderstorms winds get without a tornado?
Microbursts can produce winds of up to 150 miles per hour.
