A microburst is a downdraft (sinking air) in a thunderstorm that is less than 2.5 miles in scale. Some microbursts can pose a threat to life and property, but all microbursts pose a significant threat to aviation. ... In fact, wind speeds as high as 150 mph are possible in extreme microburst cases.

What causes micro burst?
Microbursts occur through two processes: dry air entrainment and water loading. Dry air entrainment occurs when dry air mixes in with raindrops within a cloud. ... This rapidly-descending column of air will eventually slam into the ground and spread out in all directions with winds of 60+ MPH, creating the microburst.
How long does a micro burst last?
As the name suggests, a microburst is a relatively small weather event, lasting anywhere from a few seconds to several minutes and affecting 2.5 miles or less. For downbursts affecting areas greater than 2.5 miles, Fujita used the term “macroburst.”
Is a microburst worse than a tornado?
A tornado has more of a circular or swirl pattern. Each are difficult to forecast as they form rapidly. A microburst normally lasts just a few minutes and can span an area up to 2 miles. Damage over a larger area with similar qualities and stronger winds would be considered a MACROburst.
How long does a downburst last?
They usually last for seconds to minutes. They go through three stages in their cycle: the downburst, outburst, and cushion stages.
How can you tell a microburst?
Microbursts can be identified by locating areas of convergence above the ground. When air converges above the ground, the air below will sink. Convergence can be detected on velocity products by looking for velocities from different directions that slow as they approach each other.
Can a microburst turn into a tornado?
The location in which the microburst first hits the ground experiences the highest winds and greatest damage. Wind speeds in microbursts can reach up to 100 mph, or even higher, which is equivalent to an EF-1 tornado! Winds this high can cause major damage to homes and other structures and level hundreds of trees.
Can a plane fly through a microburst?
Flying through a microburst can rapidly change the performance of the aircraft and disrupt the normal flight attitude. A microburst can quickly switch from a tailwind to a headwind, causing an increase in airspeed and performance.
How do you escape a microburst?
At smaller airports, pilot reports and your eyes are the best way to avoid a microburst. Simply put, don't fly underneath a thunderstorm. And, if you see a rain or a virga shaft descending from a cloud with dust blowing up from the ground, file a pilot report for a microburst and stay clear.
Are microbursts common?
What is a microburst? Quite often, wind damage produced from a thunderstorm is from a common phenomenon called a microburst. According to the National Weather Service, there are approximately 10 microburst reports for every one tornado, but these numbers are an estimate.
Are microbursts predictable?
The results suggest that microbursts behave somewhat differently than severe wind events, particularly in terms of lightning and VIL timing. The results dispute previous research that suggests that microbursts are highly predictable by the behavior of lightning and radar parameters.
What is a mini tornado called?
A dust devil is a strong, well-formed, and relatively short-lived whirlwind, ranging from small (half a metre wide and a few metres tall) to large (more than 10 m wide and more than 1 km tall).
What is the main difference between a downburst and a microburst?
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 gust front is the leading edge of rain-cooled air that clashes with warmer thunderstorm inflow.
What does a down burst look like?
In other words, a downburst will appear as a circular area that is half red (which denotes air moving away from the radar) and half green (which denotes air moving towards the radar).
What is the difference between a downburst and a tornado?
Downbursts happen when a strong thunderstorm that's making a lot of hail and/or large raindrops moves over an area of dry air. ... The major difference between what we see on the ground from a downburst and a tornado is that the winds from a tornado suck things inward and the winds from a downburst push outwards.
