A tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. They are often referred to as twisters or cyclones, although the word cyclone is used in meteorology, in a wider sense, to name any closed low pressure circulation. Tornadoes come in many shapes and sizes, but they are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust. Most tornadoes have wind speeds less than 110 miles per hour (177 km/h), are about 250 feet (76 m) across, and travel a few miles (several kilometers) before dissipating. The most extreme tornadoes can attain wind speeds of more than 300 miles per hour (483 km/h), stretch more than two miles (3.2 km) across, and stay on the ground for dozens of miles (more than 100 km).

Tornado is a vortex: the air around the tornado's axis rapid rotation, very central pressure decreases by tornadoes attracted tens of meters thick near the surface of a thin layer of air, the air was inhaled from all over the bottom of the vortex. And then up into the vortex around the axis, tornadoes in the wind is always cyclonic, and its center of pressure can be 10 percent lower than the surrounding air pressure. Tornadoes are associated with high-speed rotation of the funnel-shaped cloud of strong wind vortex. Tornado wind speed near the center up to 100m / s ~ 200m / s, maximum 300m / s, than the maximum wind speed near the center of typhoon good times. Central pressure is very low, as low as 400hPa, the lowest up to 200hPa. It has great sucking effect, can the sea (lake) water suction from the sea (lake) side to form a water column, and then connecting with the cloud, commonly known as "Dragon water." As the tornado is extremely thin internal air, and the temperature rapidly decreases, water vapor quickly condenses, forming funnel cloud is an important reason. Funnel cloud diameter, the average is only about 250m. Instability resulting from a strong tornado in cumulonimbus. Its formation was strongly increased with the warm air, cold air south, the terrain effects, and so on. Its life history is short, the general maintenance of 10 minutes to 12 hours, but its amazing destructive power, able to uproot trees, buildings blown down, or the part of the surface material to air volume. Jiangsu Province, nearly all tornadoes occur each year, but the place where there is no obvious rule. Occurs, usually six to seven, sometimes in August, the middle. The formation of a tornado A tornado is a product of thunderstorm clouds. Specifically, a huge thunderstorm tornado is a small part of the energy in a small area in a concentrated form of release. Tornado formation can be divided into four phases: (1) the instability of the atmosphere produced a strong updraft, due to the largest rapids in the flow of transit, it was further strengthened. (2) Since the vertical direction with the speed and direction are the interaction of wind shear, increased airflow in the middle troposphere begin rotating, the formation of mesoscale cyclones. (3) With the development of mesoscale cyclones in the ground and up to stretch, and strengthen its own thinner. Meanwhile, a small area of enhanced counseling together, that is born within the cyclone formation of tornadoes, cyclones generated in the same process, forming a tornado core. (4), tornadoes and cyclones in the core of the Rotary's different, because it is strong enough to make tornadoes has been extended to the ground. When the development of the vortex to reach ground level, the sharp decline in surface pressure, surface wind speed increased rapidly to form a tornado. Tornadoes often occur in summer lightning storm, the most common especially in the afternoon to evening. Attack range of small diameter cyclones typically between 10 meters to several meters. Tornado survival time to only a few minutes, more than a few hours. Wind particularly in wind speed near the center of up to 100-200 m / sec. Extremely destructive, tornado through the place, often occur uprooted trees, overturned cars, destroyed buildings and other phenomena, sometimes people take away a very serious hazard。

ATLANTA, Georgia (CNN) -- Waves of severe thunderstorms streaked through downtown Atlanta on Saturday, hours after a tornado left a trail of destruction through the heart of the city.
An Atlanta sidewalk is heaved up by an oak tree toppled in Friday night's storm.
1 of 2more photos ? A swath of uprooted and broken trees, downed utility lines, peeled-off roofs and collapsed brick walls marked the path of the tornado that struck around 9:40 p.m. Friday.
"This was clearly a tornado," Lans Rothfusz of the National Weather Service's Peachtree City, Georgia, office said. He rated the storm an EF-2 on the Enhanced Fujita scale, meaning it packed top winds of 130 miles per hour.
Utility and cleanup crews worked Saturday to restore traffic lights, clear streets and remove tons of debris in the city's business district after Friday night's unusual urban storm.
Atlanta Mayor Shirley Franklin and Georgia Gov. Sonny Perdue declared states of emergency.
Police in Atlanta were urging people to stay away from downtown, fearing shattered glass and hanging metal would continue to fall from buildings as new storms rolled through.
A heavy thunderstorm prompted another tornado warning as it plowed across Atlanta just south of downtown Saturday afternoon. More storms were seen forming in Alabama and heading toward Atlanta.
At least two people were killed Saturday afternoon as the same line of storms destroyed structures elsewhere in northern Georgia.
Trees blown down in Friday night's storm crushed a row of houses in the city's historic Cabbagetown district just east of downtown.
Initial estimates from the mayor's office said at least 20 of the historic homes were damaged or destroyed by the tornado.
Atlanta police Maj. Renee Propes urged people to stay away from Cabbagetown.

Tornadoes——Nature's Most Violent StormsAlthough tornadoes occur in many parts of the world, these destructive forces of nature are found most frequently in the United States east of the Rocky Mountains during the spring and summer months. In an average year, 800 tornadoes are reported nationwide, resulting in 80 deaths and over 1,500 injuries. A tornado is defined as a violently rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of 250 mph or more. Damage paths can be in excess of one mile wide and 50 miles long. Once a tornado in Broken Bow, Oklahoma, carried a motel sign 30 miles and dropped it in Arkansas!so,what causes tornadoes?Thunderstorms develop in warm, moist air in advance of eastward-moving cold fronts. These thunderstorms often produce large hail, strong winds, and tornadoes. Tornadoes in the winter and early spring are often associated with strong, frontal systems that form in the Central States and move east. Occasionally, large outbreaks of tornadoes occur with this type of weather pattern. Several states may be affected by numerous severe thunderstorms and * the spring in the Central Plains, thunderstorms frequently develop along a "dryline," which separates very warm, moist air to the east from hot, dry air to the west. Tornado-producing thunderstorms may form as the dryline moves east during the afternoon * the front range of the Rocky Mountains, in the Texas panhandle, and in the southern High Plains, thunderstorms frequently form as air near the ground flows "upslope" toward higher terrain. If other favorable conditions exist, these thunderstorms can produce *oes occasionally accompany tropical storms and hurricanes that move over land. Tornadoes are most common to the right and ahead of the path of the storm center as it comes onshore.。

tropical cyclone
Severe atmospheric disturbance in tropical oceans.
Tropical cyclones have very low atmospheric pressures in the calm, clear centre (the eye) of a circular structure of rain, cloud, and very high winds. In the Atlantic and Caribbean they are called hurricanes; in the Pacific they are known as typhoons. Because of the Earth's rotation, tropical cyclones rotate clockwise in the Southern Hemisphere and counterclockwise in the Northern. They may be 50–500 mi (80–800 km) in diameter, and sustained winds in excess of 100 mph (160 kph) are common. In the eye, however, the winds drop abruptly to light breezes or even complete calm. The lowest sea-level pressures on Earth occur in or near the eye.
熱帶氣旋 tropical cyclone
在熱帶海洋上形成的劇烈大氣擾動。熱帶氣旋中心（眼）的低氣壓帶是晴朗平靜的好天氣，外部則環繞著降雨、云和強風。在大西洋和加勒比海的熱帶氣旋被稱作颶風，而在太平洋則被稱作臺風。由于地球的自轉，熱帶氣旋在南半球按順時針方向運動，而在北半球則按逆時針方向運動。它們的直徑可達到80~800千米，一般風速可保持在每小時160千米。但熱帶氣旋的中心則只有微風甚至是平靜的海面。地球上最低的海洋氣壓出現在熱帶氣旋的中心或中心附近。
氣旋出現在熱帶緯度，由溫暖的空氣和水驅動。風環繞低壓中心“風眼”轉動，中心通常無風。在風眼壁里面或附近風雨通常最為猛烈。
