What exactly is a microburst?
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. Wet microbursts are accompanied by significant precipitation and are common in the Southeast during the summer months.
What is a microburst look like?
The damage from a microburst looks like some raked through the area from the strong winds forcing damage out in a fan or straight lined direction. A tornado has more of a circular or swirl pattern. Each are difficult to forecast as they form rapidly.
What is a downburst vs 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.
Is a microburst worse than a tornado?
Although microbursts are not as widely recognized as tornadoes, they can cause comparable, and in some cases, worse damage than some tornadoes produce. In fact, wind speeds as high as 150 mph are possible in extreme microburst cases.
What are the characteristics of microbursts?
microburst, pattern of intense winds that descends from rain clouds, hits the ground, and fans out horizontally. Microbursts are short-lived, usually lasting from about 5 to 15 minutes, and they are relatively compact, usually affecting an area of 1 to 3 km (about 0.5 to 2 miles) in diameter.
What does a waterspout look like?
A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water. Some are connected to a cumulus congestus cloud, some to a cumuliform cloud and some to a cumulonimbus cloud.
How long does a typical microburst last?
Duration: An individual microburst will seldom last longer than 15 minutes from the time it strikes the ground until dissipation. The horizontal winds continue to increase during the first 5 minutes with the maximum intensity winds lasting approximately 2-4 minutes.
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.
Are microbursts covered by insurance?
Insurance Claims for Microburst Damage The good news is that most insurance policies that cover storm damage to a home will cover the damage from a storm that produced a microburst. Ultimately, the damage in a microburst is a combination of wind, rain, and hail—all of which may be covered by the policies you carry.
What is the definition of a microburst storm?
Definition of microburst. : a violent short-lived localized downdraft that creates extreme wind shears at low altitudes and is usually associated with thunderstorms.
What kind of damage can a microburst cause?
A microburst is a localized and powerful downdraft created by a column of sinking air through the base of a storm or rain cloud. The phenomenon can be divided into dry and wet microbursts, both of which can cause severe damage to the surface and objects in their path.
How long does it take for a microburst to form?
The image to the right shows just how much damage can be caused by microburst winds. As you can see, this manufactured home was completely destroyed. Forecasting for microbursts is typically done on a near-term basis, generally within 6-12 hours before convection is expected to develop.
How is a microburst different from a tornado?
A weather phenomenon, called a microburst, may cause destruction just as devastating as a tornado does. A microburst is a small column of exceptionally intense and localized sinking air that results in a violent outrush of air at the ground.
