英文翻譯有關於氣象方面!!急!!~20點

在大氣之中,龍捲風是一種小範圍,威力很強且極具破壞力的空氣旋渦,其直徑由數十公尺至數百公尺不等,平均而言約 250公尺。自遠處看,它狀似一暗灰色的漏斗或象鼻,自雲底向下伸展至地面,整個漏斗狀雲柱本身繞著一近似垂直的中心軸呈反時針方向急速旋轉,同時向前行進。雲柱有時在空中迴盪,有時降低及於地面,所經之處常造成嚴重災害。龍捲風路徑的長度,平均在 5 到 10 公里之間,然而亦有長達 300 公里的紀錄;龍捲風的壽命有些不到一分鐘,但有些則可維持數小時,平均歷時約不到十分鐘。

因為龍捲風所伴隨的風力太強,普通測量風速的裝置無不被摧毀無遺,所以很難得到可靠的紀錄。根據建築物的損壞程度,以及飛揚物體的打擊力來估計,其風速大致在每秒 100 公尺左右,甚至可能到達每秒 200公尺以上。就歷年來侵襲台灣強烈颱風來說,中心附近最大風速亦極少超過每秒80公尺者,足見龍捲風威力之大。

龍捲風的成因迄今猶未澈底明瞭,它們大都發生在強冷鋒和颮線(鋒面前雷雨帶)附近,亦有伴隨颶風出現。台灣在春夏季亦偶有龍捲風發生,所幸因其範圍小,路徑短,很少造成重大災害;但在美國中西部龍捲風則為一嚴重天然災害。因為龍捲風常成群出現,挾帶強風且所經之處氣壓突然猛烈下降,所以具有非常強烈可怕的破壞力。

在氣象學上說颱風是一種劇烈的熱帶氣旋,熱帶氣旋就是在熱帶海洋上發生的低氣壓。在北半球的颱風,其近地面的風,以颱風中心為中心作逆時針方向轉動,在南半球作順時針方向轉動。至於颱風這個名字的來源,一般認為是從廣東話「大風」演變而來;但據林紹豪教授的考據,可能是從閩南語「風篩」演變而來,於魯鼎梅重修台灣縣志云:「所云颱者,乃土人見颶風挾雨四面環至,空中旋舞如篩」,因曰風篩,謂颶風篩雨,未嘗曰颱風也,臺音篩同台,加風作颱,諸書承誤。至今閩南語稱颱風為風颱,所以這一說法頗為可信。但無論「大風」也好,「風篩」也好,總之颱風就是發生在熱帶海洋上的 一種非常猛烈的風暴。

龍捲風和颱風有何不同?

  關於颱風的一切問題,由以前的各問中已大略的瞭解。龍捲風雖

有若干現象和颱風相似,但其發生原因、實質構造等並不相同。茲大

略說明如下:

  龍捲風是一種極強烈而危險的旋風,可發生於陸地(稱為陸龍捲

)或海上(稱為水龍捲)。其發生原因是由於熱帶濕熱氣團向北推進

,而高空則有乾冷氣團侵入,發生渦旋運動,形成濃厚之積雨雲。當

其旋渦運動愈趨猛烈時,可自雲中直降至地面,形成一漏斗狀之雲柱

,其中風力極強,估計可達每小時 160公里,甚至達到每小時 480公

里以上之風速,所以破壞力極為驚人,是所有大氣現象中破壞力最大

者。

  龍捲風範圈很小,在天氣圖上不易發覺,但因多伴生於雷雨或颱

風侵襲期間。近來氣象學家利用衛星、雷達及閃電的觀測等以研究其

詳細情形,以期於有發生可能時即發出警報,使能預先防範以減少損

失。臺灣中部及西南部平原地區,在春季及五、六月的梅雨期中常發

生龍捲風,大約平均一年有1~2次。根據實際觀測資料顯示,颱風中

亦曾伴有龍捲風或水龍捲之情形。

    In the atmosphere, the tornado is one kind of small scope, the might very strong also extremely has the destructive power the air whirlpool, its diameter is different by dozens of meters to several hundred meters, the average says approximately 250 meters. Looked from the distant place, it resembles a dark gray the funnel or the trunk, extends from the cloud base to under to the ground, entire funnel shape cloud column itself assumes the counter-clockwise direction around an approximate vertical central shaft rapidly to revolve, simultaneously forward running. The cloud column sometimes in airborne reverberates, sometimes reduces reaches to the ground, passes through it place often to create the major disaster. Tornado way length, average in 5 to 10 kilometers between, however also has the length to reach 300 kilometers records; Tornado life somewhat not to a minute, but some may maintain for several hours, the average lasted approximately not to ten minutes.

    Because the tornado follows wind power too strong, ordinary surveys the wind speed the installment to destroy all with nothing left, therefore is very difficult to obtain the reliable record. According to the building damage degree, as well as flies upwards the object to hit the impact to estimate, its wind speed approximately about each second 100 meters, even possibly arrives above each second 200 meters. Makes a sneak attack the Taiwan intense typhoon on all previous years to say that, nearby the center the maximum wind speed also extremely little surpasses each second 80 meters, indicates the tornado might to be big.

    The tornado origin still not thorough has up to now been bright, they mostly occur in the strong cold front and buao"s line (in front of frontal area thunder rain band) neighbor, also has follows the hurricane appearance. Taiwan has the tornado occurrence in the

    2006-03-22 18:04:41 補充:

    Because the tornado often in groups appears, carries under the arm the gale also passes through it place barometric pressure suddenly violently to drop, therefore has the extremely intense fearful destructive power.

    2006-03-22 18:07:53 補充:

    Until now Southern Fujian language calls the typhoon wind, therefore this view is quite credible. But regardless of "gale" also good, "the wind sieves" is also good, in brief the typhoon is occurs on the tropics sea one kind of extremely violent storm.

    Slightly explains as follows:

    The tornado is one kind is extremely intense but the dangerous tornado, may occur to the land (is called Lu Lungchuan)

    Or marine (is called water-spout). It has the reason is because the tropics hot and damp air mass advances to
