DAMAGING WINDS What are damaging winds? Damaging winds are often called "straight-line” winds to differentiate the damage they cause from tornado damage. Strong thunderstorm winds can come from a number of different processes. Most thunderstorm winds that cause damage at the ground are a result of outflow generated by a Wind Damage Insurance Roof Claim thunderstorm downdraft. 

Damaging winds are classified as those exceeding 50-60 mph. Are damaging winds really a big deal? Damage from severe thunderstorm winds account for half of all severe reports in the lower 48 states and Wind Damage Insurance Roof Claim is more common than damage from tornadoes. Wind speeds can reach up to 100 mph and can produce a damage path extending for hundreds of miles. 

Who is at risk from damaging winds? Since most thunderstorms produce some straight-line winds as a result of outflow generated by the thunderstorm downdraft, Wind Damage Insurance Roof Claim anyone living in thunderstorm-prone areas of the world is at risk for experiencing this hazard. People living in mobile homes are especially at risk from injury and death. 

Even anchored mobile homes can be seriously damaged when winds gust over 80 mph. Damaging wind from thunderstorms is much more common than damage from tornadoes. In fact, Wind Damage Insurance Roof Claim many confuse damage produced by "straight-line" winds and often erroneously attribute it to tornadoes. 

The source for damaging winds is well understood and it begins with the downdraft. As air rises, it will cool to the point of condensation where water vapor forms tiny water droplets, Wind Damage Insurance Roof Claim comprising the cumulus cloud we see. As the air continues to rise further condensation occurs and the cloud grows. 

Near the center of the updraft, the particle begin to collide and coalescence forming larger droplets. This continues until the rising air can no longer Wind Damage Insurance Roof Claim support the ever increasing size of water drops. Once the rain drops begin to fall friction causes the rising air to begin to fall towards the surface itself. Also, some of the falling rain will evaporate. 

Through evaporation heat energy is removed from the atmosphere cooling the air associated with the precipitation. As a result the cooling, the density of the air increases causing it to sink toward the earth. The downdraft also signifies Wind Damage Insurance Roof Claim the end of the convection with the thunderstorm and it subsequent decrease. 

When this dense rained-cooled air reaches the surface it spreads out Wind Damage Insurance Roof Claim horizontally with the leading edged of the cool air forming a gust front. The gust front marks the boundary of a sharp temperature decrease and increase in wind speed. 

The gust front can act as a point of lift for the development of new Wind Damage Insurance Roof Claim thunderstorm cells or cut off the supply of moist unstable air for older cells. Downbursts are defined as strong winds produced by a downdraft over a horizontal area up to 6 miles (10 kilometers). Downbursts are further subdivided into microbursts and macrobursts. 

Microbursts and Macrobursts A microburst is a small downburst with an outflow less than 2½ miles (4 kilometers) in horizontal diameter and last for only 2-5 minutes. Despite their small size, Wind Damage Insurance Roof Claim microbursts can produce destructive winds up to 168 mph (270 km/h). Also, they create hazardous conditions for pilots and have been responsible for several disasters. 

For example... 1. As aircraft descend (right) into the airport they follow an imagery line called the "glide slope" (solid light blue line) to the runway. 2. Upon entering the microburst, Wind Damage Insurance Roof Claim the plane encounters a "headwind", an increase in wind speed over the aircraft. The stronger wind creates additional lift causing the plane to rise above the glide slope. 

To return the plane to the proper position, the pilot lowers the throttle to decrease the plane's speed thereby causing the plane to descend. 3. As the plane flies through to the other side of the microburst, Wind Damage Insurance Roof Claim the wind direction shifts and is now a "tailwind" as it is from behind the aircraft. This decreases the wind over the wing reducing lift. 

The plane sinks below the glide slope. 4. However, the "tailwind" remains strong and even with the pilot applying full throttle trying to increase lift again, there may be little, if any, Wind Damage Insurance Roof Claim room to recover from the rapid descent causing the plane to crash short of the runway. 

Since the discovery of this effect in the early to mid 1980's, pilots are now trained to recognize this event and take appropriate actions to prevent accidents. Also, many airports are now equipped with equipment to detect microbursts and Wind Damage Insurance Roof Claim warn aircraft of their occurrences. 

A macrobursts is larger than a microburst with a horizontal extent more than 2½ miles (4 km) in diameter. wile also not quite a strong as a microbursts they can produce winds as high as 130 mph (210 km/h). Damaging winds generally last longer, from 5 to 20 minutes, and Wind Damage Insurance Roof Claim produce tornado-like damage up to an EF-3 scale. 

Wall of dust approaching the NWS Forecast Office in Phoenix July 5, 2011 In wet, humid environments, Wind Damage Insurance Roof Claim macrobursts and microbursts will be accompanied by intense rainfall at the ground. If the storm forms in a relatively dry environment, however, the rain may evaporate before it reaches the ground and these downbursts will be without precipitation, known as dry microbursts. 

In the desert southwest, dust storms are a rather frequent occurrence due to downbursts. The city of Phoenix, AZ typically has 1-3 dust storms each summer due to the cooler dense air spreading out from thunderstorms. On July 5, 2011, Wind Damage Insurance Roof Claim a massive dust storm resulted in widespread areas of zero or near zero visibility in Phoenix. 

The wind that produced this storm was generated by downbursts from thunderstorms with winds up to 70 mph (110 kp/h). Heat Bursts Dry heatbursts are responsible for a rare weather event called "Heat Bursts". 

Heat bursts usually occur at night, Wind Damage Insurance Roof Claim are associated with decaying thunderstorms, and are marked by gusty, sometimes damaging, winds, a sharp increase in temperature and a sharp decrease in dewpoint. While not fully understood, it is thought that the process of creating a dry microburst begins higher in the atmosphere for heat bursts. 

A pocket of cool air aloft forms during the evaporation process since heat energy is required. In heat bursts, all the precipitation has evaporated and this cooled air, being more dense than the surrounding environment, Wind Damage Insurance Roof Claim begins to sink due to gravity. As the air sinks it compresses and with no more water to evaporate the result is the air rapidly warms. 

In fact, it can become quite hot and very dry. Temperatures generally rise 10 to 20 degrees in a few minutes and have been known to rise to over 120°F (49°C) and Wind Damage Insurance Roof Claim remain in place for several hours before returning to normal. Derechos 

If the atmospheric conditions are right, widespread and long-lived windstorms, associated with a band of rapidly moving showers or Wind Damage Insurance Roof Claim thunderstorms, can result. The word "derecho" is of Spanish origin, and means straight ahead. A derecho is made up of a "family of downburst clusters" and by definition must be at least 240 miles in length.
