英語龍卷風閱讀理解

A. 龍卷風的英語

tornado [tɔ:'neɪdəʊ]，龍卷風。

B. 【龍卷風】閱讀答案

①盛夏季節，在天氣預報里經常可以聽到這樣的話：「台風中心的風力在十二級以上。」似乎這十二級就是風力之「最」了。自然界中還有比這更大的風嗎?有，這就是龍卷風。
②龍卷風俗稱「龍吸水」，這也許是它漏斗狀雲柱的外形很像神話中的「龍」從天而降，把水吸到空中而得名的吧。實際上，它是從雷雨底伸向地面或水面的一種范圍很小而風力極大的強風旋渦。
③龍卷風的風力極大。在龍卷風中心附近，水平風速每秒可達100米以上，極端情況下可達300米。十二級台風的風速相當於每秒30米，要和龍卷風相比，自然就大為遜色了。如此罕見的巨大的風，造成的破壞是非常驚人的。當它觸及地面時，可以把人畜開玩笑似地卷到天空再扔下來，它可以「倒拔垂柳」，摧毀建築物，甚至可以把堅固的高樓大廈攔腰斬斷。1956年9月24日，上海曾出現過一次龍卷風，它竟然把一個三四層樓高的100噸的儲油罐舉到15米的高空，然後把它甩到100米遠的地方。1925年，美國曾出現過一次強大的龍卷風，造成2000多人的死亡。為什麼龍卷風的風力這么大?主要是龍卷風內的空氣大量逸散，使龍卷風中心的空氣十分稀薄，氣壓很低，與外圍空氣的氣壓差特別大。(A)台風中心的空氣與它外圍的空氣平均每100公里氣壓差為20毫巴(壓強單位)，而龍卷風中心與它的外圍空氣只相差20米，氣壓差就達20毫巴。(B)難怪龍卷風的風力要比台風大好多倍。
④龍卷風涉及的范疇范圍很小。1972年美國南卡羅萊納州的一次龍卷風，在它經過的15平方米的范圍內，大樹被連根拔起，而靠近這股大風的地方則安然無恙。
⑤龍卷風雖然破壞性極大，令人可怕，然而龍卷風也是可事先預報的，氣象雷達就是監測龍卷風的一種很好的工具。我們堅信不久的將來，人類不僅能監測預報龍卷風，而且還能利用龍卷風巨大的風造福人類。

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.

Tornadoes harm In 1995 in American Oklahoma adeimantus Moore city in a LiuLong volumes, such as roof heavy objects such blown out of ten miles away.

In intense tornadoes, house roof like hang 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.

2004 high temperature, typhoons and other natural disasters cause From June to date, global natural disaster events ridden, aberrant natural signs emerging that all clearly show the "negative edge" energy fluctuations has become pronounced. If you glance at the first chapter of the "universe" Title IV cosmic energy fluctuations chapters, you will come to a conclusion : as stated in the text "negative capability" for the Earth and the resulting energy disturbance mechanisms of unusual natural phenomenon occurring with the current global natural disaster events are exactly the same. How to look at the various recent unusual natural phenomenon, the scientific interface before the former seems insurmountable obstacles. According to the American Federation of the meteorological weather forecasting centres experts claim that in the central tropical Pacific sea area, a new "El Nino" is taking shape, and this year in August, the central and western equatorial Pacific sea water temperature 0.5 degrees higher than normal, is higher than normal levels for the third consecutive month, temperature rise in the area transport volume increased, thus affecting the pressure and wind, and other phenomena. What the recent global temperature anomalies sudden weather, floods and hail storms, typhoons and hurricanes follow on somebody's heels from various, Tornado endless, frequent seismic activity, volcanic eruption, the emergence of red tides in the oceans, biological phenomena in a series of unusual reactions, etc. This new "El Nino" was formed. Let us go on the "El Nino" is to explore issues such as how to create and has been a controversy, if you are interested visit to the "universe" ... Section V of Chapter VIII of the oceans mark content, you will be so-called "El Nino" argument jeer at the nose, in fact, only to "hydrosphere" caused by the change of certain energy is a clear characteristic of certain marine climate climate change, is clearly insufficient to fully explain the Earth's ecology as a whole chain of energy interaction between the various mass arising from the series of tangled complex natural phenomena. Face reality, we always have to seek out a more reasonable and satisfactory answers to explain a little what have happened, the responsibility naturally fell on the scientific community itself, however, I just heard a "common" voice in member of gentry moan. I also listened to the observation of graally lost patience, because I clearly see the Earth in the "negative edge" of the disturbance left eye picture, but we are indifferent, of course, this refers to the "cosmic X precursor" after publication issued many more Unfortunately, We have already missed the summer solstice (June 21, 2004) Sun, Moon, Earth and biological science comprehensive monitoring and collecting all information and data best time, a matter of concern is the date of the Winter Solstice (December 21, 2004) footsteps may have been clear cases of all is unusually quiet. Is the future really not escape. Although we have no way to prevent future will be happening, but they can adopt scientific methods to monitor the future of certain events may arise, and this is what we currently do and do work. Let us start from this article, here, I will work with everyone along the "negative edge" disturbance footsteps forward to sharing the magic forces of nature to create a miracle. "negative edge" energy fluctuations in the Earth's energy disturbances from the Earth's perspective the main mechanisms and micro perspective of life on two aspects (please refer to the Title IV chapter cosmic energy fluctuations). Currently can confirm that from the macro perspective of Earth, "negative capability" to the Sun, Moon and Earth disturbance of natural ecosystems has led to the current series of unusual response, and "negative influence" on the life of micro-organisms also revealed a slight signs estimated at the date of the Winter Solstice (December 21, 2004 or December 22, 2005) full appearance. 1 : Earth perspective. Mainly "negative power" disturbance caused Sun, Moon and Earth energy balance generated fluctuations. 1, solar energy fluctuations : Please readers first glance at the chapter IV sunspot ... 8 "x" Planet Earth chapters on the causes of reading, or help the reader to the next analysis of the recent sudden temperature hot global extreme climate events. Let us look at the following data : This year, the average temperature in most parts of China over the same period in High perennial, two months late, a total of 17 provinces near the average temperature set a new record. In mid-April, the Northeast South, the North China, Huang accurate, and the Northwest Northeast High 4~ degrees Celsius, some parts of the high temperatures above 35 degrees Celsius, the maximum temperature reached Shanxi Island 37 degrees Celsius, a new record high. Inner Mongolia, Jilin, Liaoning continued low rainfall in parts, high temperature, severe drought, which caused ration and intensity rare for 100 years. In mid-May, most parts of China since the beginning of this year the widest range and intensity of the largest precipitation process, accompanied by thunderstorms, strong winds, hail, and strong convection weather. Jiangxi, Guangdong, Guangxi, Guizhou, Sichuan and Chongqing in a rainstorm and flooding. In late June to early July, a South China heat and the gulf between the northern region rainstorm peculiar phenomenon, most of the southern part of hot weather over 36 degrees Celsius in some areas such as Guangdong, Hong Kong and even recorded 40 degrees Celsius above-historical record of extreme heat. Over the same period, the northern region received heavy rains and serious rainstorm. July's theme is global temperature and the extreme weather storms constantly staggered, with the exception of parts of the plateau, Siberia and the USA and Central perennial low temperatures than 2 degrees Celsius above, much of the rest of high temperature, which in northern Europe to north-west Siberia, Mongolia northeast, the Far East, Eastern, Alaska and the western United States is the western sea High 2~4 degrees Celsius. At the European Southern Spain, Portugal, Greece, Macedonia and Romania by the sudden heat wave, resulting in dozens of deaths. Greece recorded a maximum temperature of 42 degrees Celsius above, Japan is a 1923 record heat. Balkhash Lake to the European Central region, Southeast Asia, the United States central and eastern, western, the western coast of Australia, South America and southern most parts of 5% to 1 times the precipitation side, partially cut more than two times. Northeast India, Bangladesh, Nepal, Bhutan and Afghanistan have suffered serious flooding, Canada Alberta, Ontario and Quebec and other places respectively by the hail and heavy rain hit attack. August extremely high temperatures in the context of the continuing worldwide, Denmark has sustained high temperatures, the average temperature over a perennial Japan High 2~6 degrees Celsius ring the same period, which Mr. Salih day maximum temperature over 32 degrees Celsius. Iceland also experienced the highest temperature ever recorded in Iceland capital Reykjavik night temperature reached the highest value on record (24.8 degrees Celsius), Siqiafu Dafeide region daytime maximum temperature reached 29.1 degrees Celsius, close to the historical record (29.2 degrees Celsius). The heat is swept across China throughout North and South, high temperature hot weather usually sudden, and lasted longer, and the wide distribution area is unprecedented. Chang, Jiangnan, South China, Sichuan region from 35 to 38 degrees Celsius heat, Chongqing, Jiangxi, Zhejiang, Fujian, and other local areas of extreme heat also more than 40 degrees Celsius. August 9, Fujian has 13 Stations maximum temperature greater than 38 degrees Celsius, which is six more than 39 degrees Celsius station, the temperature reached 40 degrees Celsius will Yue County; Jiangxi 87 counties and cities in 71 counties and cities in maximum temperatures over 37 degrees Celsius, including 25 cities and counties in 39 degrees Celsius maximum temperature, Suichuan, Hengfeng daily maximum temperature reached 40.1 degrees Celsius and 40.0 degrees Celsius respectively. In addition, Beijing, Shanghai, Heilongjiang, Guangxi, Liaoning, Inner Mongolia, Hebei, Gansu, Shandong, Anhui, Hunan, Hubei, and other places have emerged 35~38 degrees Celsius temperature 40 degrees Celsius in some areas is the extremely high temperature control. September high temperatures eased up around the world, with temperatures graally decline, northern China Nanjing, Jiangsu prospective area south of the river, eastern Anhui, Zhejiang north, Shanghai and other places were a rare large-scale smog has shrouded. Manuel, seahorse, Ivan, Jennifer, etc. Typhoon become the leading force in September, further exacerbated by the ravages of Hurricane global catastrophe losses. Various natural disasters this summer events lasted longer and spread more extensive, is a great power has never occurred in recorded history. What causes the sudden emergence of global temperature this summer's hot extreme weather events? Clearly "El Nino" theory is unable to obtain a satisfactory answer. Obviously, if we think that this summer there is an unusually high temperature phenomenon accident, be considered as such as "El Nino", Am shafts, strong reversal wind belt convection, thermal effects, and so on the so-called salt transport volume of the marine climate features such unusual cases viewed, then we are dead wrong. I am in the "universe" is the book proved "negative forces" has led to disturbances in 2002, 2003 date of the Winter Solstice SARS and the avian flu outbreak has, and thus dece the "negative edge" energy fluctuations will turn from the ocean depths, surface, the atmosphere into space gradient moving, community will arise abnormal natural phenomena, final mass outbreak of the virus contamination of water pollution. As long as we recall in 2002, 2003 sudden outbreak of SARS and the avian flu and various natural factors, and then linked to the recent high temperatures, torrential rains, typhoons, cyclones, earthquakes, volcanoes, red tide, natural disasters, etc. Biological perverse phenomenon, We will understand that global temperatures hot summer extreme climate events is not marine -- "hydrosphere" the ability of energy changes, the unusual weather extreme heat simply "negative edge" energy fluctuations of the Earth energy disturbances moving constantly into the inevitable results. Then, the "negative impact" on how to move into? In other words, "negative capability" is how disturbances caused by the recent global high-temperature events? As long as you explore with the spirit seriously the "universe," a book thoroughly study it again, I believe we can find a satisfactory answer. Climbing, I do not have enough time to the "negative impact" and the solar system, the Sun, Moon and Earth, space and Earth temperature winter climate is formed, and so on with various complex issues in this repeat, but the conclusions could still be here simply to note : "negative forces" disturbances in the solar energy generated fluctuations, energy fluctuations caused by the summer sun finally emerging global sudden high temperature events. "negative forces" to lead to fluctuations in solar output problems please readers in the "universe" of a book seek an answer, as the volume of solar fluctuations is causing the Earth to the sharp rise in temperature, let us first put aside the "positive influence", the universe, the solar system, the Moon, Earth factors interaction that is set aside sunspot, tidal and ocean currents, sandstorms, volcanic eruptions, earthquakes, drought, blow wind, tornadoes, torrential rains, floods, hail, marine red tide, biological anomalies, the greenhouse effect and so on various natural phenomena. On the case this summer to a high temperature solar energy analyzing how fluctuations caused by the Earth's temperature is a space temperature volatile climate characteristics As the month of June, the Earth graally transferred to the recently Point (summer solstice on June 21), "10" energy pattern "negative forces" axis location, the sun, Earth and the Moon by "x" planetary and "negative edge" disturbance force increases. First, marine and terrestrial biological unusual, followed by the active volcanoes around the world affected by the earthquake phenomenon is more frequent. From the perspective of looking at the global temperature changes, we found that the temperature change is a clear regional distribution : June period, the global temperature distribution throughout a state of disorder. June 21 (summer solstice), the late June to early July, a southern region of China and the northern region high rainfall big gulf between the special circumstances. In late July, the situation is quite the opposite, and the Chinese southern region received heavy rains in the northern parts of a sudden temperature rise unusually sharp temperature conditions. August, the Chinese Ministry of areas north and south at high temperatures and heavy rains are interlocking disorderly distribution situation. From the global total shows that the world is basically the same period also show a similar north-south China's Ministry of areas of the regional distribution of high temperature and heavy rains. Why is there this summer, the regional distribution of high temperature and heavy rains from disorderly -- orderly -- the rhythm to disorderly? Obviously, when transferred to the Earth and the recent point (summer solstice on June 21), on the one hand, the Earth is in the absorption of the universe, solar end of the axis location; On the other hand, the functioning of the Earth is to "x" planetary ecliptic belt crossroads. Meanwhile, the volume of the Earth by solar fluctuations greatest influence, by the same "negative edge" energy fluctuations of the strongest military power. "universe" is a book of detailed studies of SARS and the avian flu outbreak has been subjected to "negative forces" e to disturbances, "negative capability" disturbances caused by solar emissions, fluctuations in the volume of low solar fluctuations and affect the Earth's energy balance space temperature changes, resulting in the temperature of Earth drastic changes, resulting in high-temperature hot summer suddenly very Shui climate phenomena. Estimated "negative edge" energy fluctuations is a "two Xianbo" cyclical fluctuations, when the "negative edge" energy fluctuations in the minimum period to exert pressure on the sun weakened, solar radiation to the Earth energy increases, resulting in a sharp rise in the Earth's temperature to a very Shui heat this summer climate anomalies. When the "negative edge" energy fluctuations in the peak, the sun was exerting increasing pressure, solar radiation energy consequent weakening of the Earth, the Earth's temperature to drop rapidly, and eventually the emergence of strong rainstorm anomalies. It is subject to the "negative impact" fluctuations peak period, late June to July, high temperatures and heavy rains north and south of the regional orderly distribution has also become possible, the month of August away from the Earth has recently point out the "negative edge" three powerful engine control, high temperature and the distribution of rainstorm and no obvious regional speak. Of course, this summer's unusually high temperature conditions still exist "positive influence" and "negative edge" energy interaction, the major stars of mutual mistake moving solar system, Earth and the Sun and the Moon, etc. among them many factors in this statement to 11 tables. Overall, the mutations of life on Earth and the natural environment of any abnormal change the phenomenon is not just happen, which is hidden very deep secret complex, far beyond human imagination, not to mention any human since a string Yiu so-called "scientific" power. Second, the Moon energy fluctuations Please visit ... readers VIII V oceans imprint, help us understand the formation of the Moon on the Earth's atmosphere and the great role played by the perfect and the only correct understanding of ocean currents and tidal ocean real causes of the Moon and we can exist between the numerous marine ties Life in the changing nature of the world where understanding the pulse beating. This summer, what with no hurricanes, storms, floods left a deeper impression on people today, torrential rain swept across the globe, hurricanes Wherever he went a barren mess in the face of the forces of human nature seems less how little vague. Squally in the arena finally opened on June 21 screen tent, June 25, 7th Typhoon "pretty" in the East Pacific Ocean formed, July 1 from Taiwan forced landing; Until August 10, has accumulated six typhoons followed, one. August 12 14th strong typhoons "cloud her" raging China's Zhejiang Province, to hit Jiangxi; When the Asian countries frequent emergencies, August 12 on the other side of the Pacific Island of the United States are subject to a Florida hurricane "of profits" attack "of profits" since 1992 "Andhra Lu" hurricane struck Florida Chau has a most powerful hurricane; "cloud her" left, on August 16 on the 16th strong tropical storm pond from East to West direction flew straight into the Pacific, August 17 through China Zhejiang, Shanghai, Jiangsu, Taiwan; after 1, strong typhoons "U.S. Bank" to 126 kilometres per hour speed Kuangsao Japanese island; Asian countries also could catch, 18th tropical storm "debuts" on August 20 in the northwest Pacific sea and generated a 12-class strong typhoons and 8 with 25, "debuts" in a north-westerly direction to 140 kilometres per hour speed long-distance, direct volume Taiwan, Fujian ;8 30, and a strong typhoon "Siam hop" strong wave upon wave landing Japan. Squally dance is one climax after another, a busy, the whole world is in crisis. Unfortunately again fallen USA, September 2 months, hurricanes, "Francis" 233 km per hour speed engulfed him Florida Island; Asian countries are foreign-it, than a "debuts" 15 more powerful typhoon "Santa" slow in a 1,600 km passing over Taiwan on September 4, hit Japan. Squally rain raging around the world, no country is immune. In the rare and Tornado is used, blossom everywhere, the coverage is too Tornado losses. It is worth mentioning here on August 27, Beijing emerged 55 years most violent "wind st." meteorological experts since the founding of the PRC in Beijing at the weather information that had never found such a strong "st.

Tornadoes——Nature's Most Violent Storms

Although 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 ring 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， causes tornadoes?

Thunderstorms develop in warm, moist air in advance of eastward-moving cold fronts. These thunderstorms often proce 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 tornadoes.

During 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-procing thunderstorms may form as the dryline moves east ring the afternoon hours.

Along 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 proce tornadoes.
Tornadoes 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.
