http://www.nssl.noaa.gov/edu/storm/

Extractions: We can see thunderstorms with a variety of tools. Radars let us see where rain and hail are located in the storm. Doppler radars also let us see how the wind is blowing within and near the storm. Some features of thunderstorms, such as the anvil that spreads out at the top of the storm, can be seen from satellites. What type of damage can they cause? Many hazardous weather events are associated with thunderstorms. Fortunately, the area affected by any one of them is fairly small and, most of the time, the damage is fairly light. Lightning is responsible for many fires around the world each year, as well as causing deaths when people are struck. Under the right conditions, rainfall from thunderstorms causes flash flooding, which can change small creeks into raging torrents in a matter of minutes, washing away large boulders and most man-made structures. Hail up to the size of softballs damages cars and windows, and kills wildlife caught out in the open. Strong (up to more than 120 mph) straight-line winds associated with thunderstorms knock down trees and power lines. In one storm in Canada in 1991, an area of forest approximately 10 miles wide and 50 miles long was blown down. Tornados (with winds up to about 300 mph) can destroy all but the best-built man-made structures. How does atmospheric pressure change in and around thunderstorms?

Extractions: Source: USA TODAY research by Chad Palmer, Graphic by John Herne A look inside a thunderstorm The key ingredient that defines a thunderstorm is lightning. Since lightning creates thunder, a storm with lightning is called a thunderstorm. Thunderstorms come in all shapes and sizes with some cells only a few miles in diameter and some clusters of storms, known as mesoscale convective complexes , that span hundreds of miles across.

Extractions: Lightning and Storms Chase Day Can high wind bend a channel of lightning? It appears to be happening in this images taken in western Oklahoma. Strong winds form a gust front into a shelf cloud along the leading edge of the storm. Storms with this configuration are usually fast movers with strong straight line winds. This cell was moving east at 60 m.p.h. The blue color is from the film, but I liked it so I left it. Want to learn more about the lightning and understand what's going on in these storms? Kids can learn more about lightning by visiting sources such as the National Geographic Page on lightning . Lightning extending from thunderstorms into space is a new area of study and may be observed in special situations involving very clear dark skies. Cloud to ground lightning looks the best when it's out of the rain. Two types of lightning are in the first image. Lightning under the cloud base that on the edge of the rain and lightning coming out of the anvil striking outside the edge of the storm. Both are clear of the rain area and show good branching. Lightning is common in a tornadic thunderstorm, but often after the tornado is on the ground the lightning diminishes. This was a lucky shot, well not total luck, I was there. It's really hard to do this, as I have tried for years. On numerous occasions I have had a tornado in the lightning and something goes wrong to keep me from getting it. One time I had two tornadoes going on simultaneously in the lightning east of Wichita, Kansas. I broke out of the storm too close to them and they just roared by as I was trying to get set up. For this shot I was on a little hand tripod setting on the car hood, which is fast to set up, and it wasn't raining so I could stand outside.

Extractions: You are here: Main Civil Defense THUNDERSTORMS AND LIGHTNING (OCDA) It is estimated at any given moment nearly 2,000 thunderstorms are in progress over the earth's surface, and lightning strikes the earth 100 times each second. There are about 45,000 thunderstorms daily and 16 million annually around the world. There are at least 100,000 thunderstorms annually across the United States. Statistics from 1959-82 for the United States show that 2,430 people have lost their lives, and 5,882 have been injured by lightning, an average of a little over 100 people killed and about 250 injured each year. Property loss is estimated in the hundreds of millions of dollars annually. At the U.S. Commerce Department's National Oceanic and Atmospheric Administration (NOAA), scientists monitor and predict these storms. NOAA's National Weather Service keeps a round-the-clock vigil on atmospheric conditions and issues watches and warnings for severe thunderstorms. Project officials at NOAA's Environmental Research Laboratories seek new tools and improved understanding of thunderstorm processes. Scientists probe storms with radar, satellites, lightning detective devices, laser beams, and aircraft.

Extractions: Disaster from a Kid's Point of View Important Terms Sabrina's Lightning Safety What is Lightning? ... Lightning Fact and Fiction hile thunder won't hurt you - lightning will! So it's important to pay attention when you hear thunder. Thunderstorms happen in every state and every thunderstorm has lightning. Lightning can strike people and buildings and is very dangerous. Thunderstorms affect small areas when compared with hurricanes and winter storms. The typical thunderstorm is 15 miles in diameter and lasts an average of 30 minutes. Nearly 1,800 thunderstorms are happening at any moment around the world. Despite their small size, all thunderstorms are dangerous. Every thunderstorm produces lightning, which kills more people each year than tornadoes. Heavy rain from thunderstorms can lead to flash flooding. Strong winds, hail, and tornadoes are also dangers associated with some thunderstorms. You can estimate how many miles away a storm is by counting the number of seconds between the flash of lightning and the clap of thunder. Divide the number of seconds by five to get the distance in miles. The lightning is seen before the thunder is heard because light travels faster than sound. (Of course, get safe shelter first, before you take the time to count the seconds!) Thunderstorms need three things: Moisture - to form clouds and rain.

thunderstorms. There are three types of thunderstorms Air mass thunderstormsare usually produced in areas of very little vertical shear.
http://weather.cod.edu/sirvatka/ts.html

Extractions: The photos were taken from the storm spotters guide at the University of Illinois' Daily Planet web page. Although the natural environment does not fall into three distinct categories, we break them down to help illustrate significant differences. The differences arise because of varying atmospheric profiles, especially those concerned with vertical shear, defined as the change in wind velocity (speed or direction) with height, or The air mass thunderstorm is a common and usually non-severe phenomenon that forms away from frontal systems or other synoptic-scale disturbances. They form where moist and unstable conditions exist in the atmosphere. Air mass thunderstorms are usually produced in areas of very little vertical shear. As a result, the threat for severe is small. When they do reach severe limits, the thunderstorms may produce brief high winds or hail which develop because of high instability. These storms are know as pulse severe storms. Although several storm cells can develop, each individual cell lasts about 30-60 minutes and has three stages.

http://www.co.honolulu.hi.us/ocda/thunder1.htm

Extractions: You are here: Main Civil Defense WHAT ARE THUNDERSTORMS? (OCDA) Thunderstorms, generated by temperature imbalances in the atmosphere, are a violent example of convection. Warming of the air near the earth's surface and/or cooling of the air above puts warmer, lighter air layers below colder, denser layers. The resulting instability causes convective overturning of the layers, with heavier, denser layers sinking to the bottom and the lighter warmer air rising rapidly. Mechanical processes are also at work. Warm, buoyant air may be forced upward by the wedge-like undercutting of a cold air mass or by flowing up a mountain slope. Winds blowing into the center of a low-pressure area may force warm air near that center upward. In the first stage of thuderstorm development, an updraft carries warm air to a level where the air becomes saturated with moisture and visible droplets appear as a cloud begins to form. Continued upward movement produces large clouds resembling rising mounds, domes, or towers, known as cumulus clouds. Strong winds above the developing clouds may further enhance the updraft or convection. As the cloud forms, water vapor changes to liquid and/or frozen cloud particles. This results in a release of latent heat that takes over as the principal source of energy for the developing cloud. Once the cloud starts to form by other forces, this release of heat helps keep it growing.
