⑴ 关于龙卷风的英文介绍

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 proct 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 proced a strong updraft, e 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

A tornado is a violently rotating column of air which is in contact with both a cumulonimbus cloud or, in rare cases, a cumulus cloud base and the surface of the earth. Tornadoes come in many sizes but 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.

Most tornadoes have wind speeds between 40 mph (64 km/h) and 110 mph (177 km/h), are approximately 250 feet (75 m) across, and travel a few miles (several kilometers) before dissipating. Some attain wind speeds of more than 300 mph (480 km/h), stretch more than a mile (1.6 km) across, and stay on the ground for dozens of miles (more than 100 km).[1][2][3]

Although tornadoes have been observed on every continent except Antarctica, most occur in the United States.[4] They also commonly occur in southern Canada, south-central and eastern Asia, east-central South America, Southern Africa, northwestern and southeast Europe, Italy, western and southeastern Australia, and New Zealand.[5]

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 st. 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).

Terrible tornado Tornadoes, we may have all heard, but everyone to the tornado familiar? Let me introce! Tornadoes are vortex: air around the shaft spinning coil dragon, the dragon roll centre pneumatic extreme decrease attraction, near the ground dozen meters thick a thin layer of air inside, air is from all directions inhaled vortex bottoms. And immediately he turned around the axis of eddy current, the dragon roll up the wind always cyclones sex, the center of the air pressure can than surrounding low air pressure to 10 percent. Tornadoes power is strong, harmfulness is very big also. In 1995 in American Oklahoma adeimantus Moore city in a land tornadoes, heavy objects such as roof blown out of ten miles away. Most debris falls on land tornado channel of the left side, by weight ranged often have a well-defined landing zone. The lighter fragments could fly to more than 300 kilometers outside before landing. Dragon volumes of attack suddenly and violently, proce the wind is the strongest in the ground. In the United States, a tornado annually cause deaths after the thunder. It for building destruction is quite serious, often be devastating. In intense tornadoes, house roof as gliding like flying. Once the roof coiled left, other parts of the house will follow destruction. Therefore, building houses, if can strengthen the roof of the firm sex, will help to prevent tornadoes caused heavy loss ring transit. When we encounter a tornado coming, we should take the following methods from a tornado attack: first, when a tornado coming, if we at home, you should immediately ran downstairs stair avoid tornados. Second, the United States is a tornado in most places, most foreign - 8pm, the time in had better not to travel to the USA. Three, tornado coming in driving bicycle should immediately discard all items, such as low into the subway of place. Fourth, in the wilderness meet tornado should find solid rock, and couldn't find words, should avoid a tornado in bridge. On the hillside should find a quick relatively big rocks from a tornado. Tornadoes which side, you should avoid in rock in the opposite direction, When a tornado after a rock, should immediately swap places, in the opposite direction to avoid it. Well, now you should have further understanding of tornado! When you're really in a tornado, they should take the above method to escape!

tornadoes A tornado was a mystery for a long time, it is precisely because of this reason, so it is necessary to understand it. Tornadoes suddenly and violently, proce the wind is the ground the strongest. Because of its occurrence and dispersed all extremely sudden, so it is difficult to it effectively observation. What is a tornado Tornadoes are vortex: air around the shaft spinning coil dragon, the dragon roll centre pneumatic extreme decrease attraction, near the ground dozen meters thick a thin layer of air inside, air is from all directions inhaled vortex bottoms. And immediately he turned around the axis of eddy current, the dragon roll up the wind always cyclones sex, the center of the air pressure can than surrounding low air pressure to 10 percent. The formation of a tornado Tornadoes are the proct of thunderstorms in the clouds. Specifically, a tornado is a small part of thunderstorm enormous energy in small area concentration release of a form. Tornadoes formation can be divided into four stages: (1) atmospheric instability proces strong updraft, e to the biggest airflow passing through the rapids influence, it is further enhanced. (2) e in vertical direction and speed and direction are shear wind interaction, of the troposphere updraft in central to begin to spin, forming the mesoscale cyclone. (3) with the mesoscale cyclone to ground development and upward extend, itself tapers and strengthening. Meanwhile, a small area of the enhanced auxiliary close, namely born dragon coils in cyclone is formed within the same process, generate cyclones, forming a dragon roll core. (4) dragon roll core of rotating and cyclone the different, its strength enough to make dragon roll extends to the ground. When the development of the vortex arrive ground height, the earth pressure drop dramatically and the ground wind has risen sharply. Formation dragon volumes

Tornadoes detection Tornadoes wind what size is it? Nobody really knows, as tornadoes occur to dissipate the short time, the effect area too small, so the existing detection instrumentation no sensitive enough to a tornado in accurate observation. Relatively speaking, doppler radar was effective and a common observational instruments. Doppler radar alignment tornado issued by microwave beam, microwave signal the tornado crumbs and after heavy rain reflected by radar receiver. If the tornado stays away from radar, reflected back to microwave signal frequency will be the low-frequency, Conversely, if a tornado getting closer to the radar is reflected back to high frequency signals will be direction. This phenomenon has been called the doppler frequency. Receiving signal after, radar operator can through the analysis of the data, and calculates the frequency shift of tornado speed and direction of movement.
