head wind 中文意思是什麼
head wind
解釋
逆風，頂頭風。-
The plane bucked a strong head wind.
飛機頂著強風飛行。 -
Based on the sha lo wan profiler data at 0740utc, the vertical shear at around 1, 100 ft was close to 8 kt per 100 ft. although this was lower than the 8 kt per 100 ft which has been used in the windshear warning system at the old kai tak airport, the increase in head wind was nonetheless significant due to the steep climb angle
根據沙螺灣的氣流剖析儀在0740utc錄得的資料顯示，在約1 ， 100尺的垂直切變接近每百尺每小時8海里。雖然此切變低於以往啟德機場的風切變警報系統所用的每百尺每小時8海里，但因為陡峭的爬升角度，令到逆風的增加變得顯著。 -

They were, says mr stephen, and the end was that the men of the island, seeing no help was toward as the ungrate women were all of one mind, made a wherry raft, loaded themselves and their bundles of chattels on shipboard, set all masts erect, manned the yards, sprang their luff, heaved to, spread three sheets in the wind, put her head between wind and water, weighed anchor, ported her helm, ran up the jolly roger, gave three times three, let the bullgine run, pushed off in their bumboat and put to sea to recover the main of america
「此語不差」 ，斯蒂芬先生曰， 「其結果，本島男子發現負情女子異口同聲，無可救藥。遂建造舟筏，攜家財登船，桅桿盡皆豎起，舉行登舷禮，轉船首向風，頂風停泊，揚起三面帆，在風與水之間挺起船首，起錨，轉舵向左，海盜旗迎風飄揚，三呼萬歲，每次三遍，開動艙底污水泵，離開兜售雜物之小舟，駛至海面上，航往美洲大陸。 」 -

The shear experienced by the departing aircraft was due to vertical shear as the plane passed through the low level jet. based on the winds measured on - board a flight departing 8 minutes earlier, there was a rapid increase in head wind component, from 13 kt at 1, 420 ft to 39 kt at 3, 100 ft
起飛的飛機所遇到的風切變是由於該機經過低層急流的垂直切變所引致，根據一架在8分鐘前起飛的航機量度到的風速，顯示逆風由1 ， 420尺的每小時13海里急速增加到在3 ， 100尺的每小時39海里。 -
Eg. the entire ship paused and shuddered as the sails were taken aback by a sudden strong head wind
由於一陣強烈的頂頭風突然把帆吹翻過來，船一下子停住，不斷震動。 -
It lurks in the sky and when the time is right, it rushes towards the ground causing significant downdraughts and changes in head wind. microburst first coined by t. fujita, is so dangerous that every pilot would try to avoid it, especially during take - off and landing
隱藏在天空中，只待時機成熟就沖向地面，造成顯著的下沉氣流和逆風變化，這就是微下擊暴流。微下擊暴流這個現象的名稱由藤田首創。 -
