microburst 中文意思是什麼

microburst 解釋
微下暴流
  1. An aircraft flying through a microburst may first encounter an increasing headwind and lift, then a downdraft from above the aircraft, followed by an increasinig tailwind and sink

    飛越微下擊暴流的飛機可能首先會因逆風增強而浮力增加，隨即遇到上空的下沉氣流，繼而因順風增強而沉降。
  2. The emphasis in this composition is windshear signal processing technology. some processing methods are introduced in detail, they are suppressing clutter, extracting windshear parameters, computing hazard factor and etc. the signal processing simulation is accomplished on computer, it includes simulating microburst echo signal, simulating ground clutter echo signal, filtering clutter, estimating wind speed and calculating hazard factor. from the simulated results, a dangerous windshear is detected 5o ~ 78s, so the radar performance meets the certification requirements proposed by faa and nasa

    本文重點研討了風切變信號處理技術，對雜波抑制技術、風切變特徵參數提取技術及危險因子計算方法等內容進行了深入的研究，並進行了計算機模擬，包括微下擊暴流回波信號模擬、地雜波回波信號模擬、雜波抑制、風速提取和危險因子計算。

    機場多普勒天氣雷達tdwr探測到這些脈沖后，在二零零一年七月六日整晚間歇地發出微下擊暴流警告。
  6. Capturing these pulses, the terminal doppler weather radar ( tdwr ) issued microburst alerts intermittently throughout the evening of 6 july 2001

    機場多普勒天氣雷達（ tdwr ）探測到這些脈沖后，在二零零一年七月六日整晚間歇地發出微下擊暴流警告。
  7. 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。
  8. Microburst minus 30 knots on final approach

    微下擊暴流風速減少達30海里小時最後進場。
  9. Microburst minus 30 knots on final approach. a trial has started on 1 april 2003 and will last for 6 months

    微下擊暴流；風速減少達30海里/小時；最後進場。
  10. To overcome the adverse effect of the microburst, the pilot needs to take timely corrective action to ensure aircraft safety

    飛行員必須及時採取修正行動，以確保飛機安全，不致受到微下擊暴流的影響。
  11. Microburst first coined by t. fujita, is so dangerous that every pilot would try to avoid it, especially during take - off and landing

    因為其危險的緣故，任何機師在起飛和降落的時候都避免遇到微下擊暴流。
  12. Pilots not familiar with this alerting principle may be caught by surprise when on approaching the airport they first experience a gain event windshear of 15 kt instead of a loss event microburst of - 30 kt at the first encounter 3 mile final location only to encounter a loss of - 30 kt a couple of seconds later at 1 mile final

    他們在三海里處首次相遇位置所遇到的，並不是風速減少的情況- 30海里/小時的微下擊暴流，而是風速增加的情形+ 15海里/小時的風切變。而於數秒後到達最後進場1海里處卻遇到- 30海里/小時的風速減少情況。
  13. The idea is that the microburst or windshear alerts passed by the air traffic controllers to the pilots should include the location i. e. runway or 1, 2 or 3 nautical miles from runway threshold of the first encounter of the microburst or windshear event i. e. first encounter and the maximum value of the computed wind speed difference i. e. maximum intensity

    這準則的構思是，所有經航空交通管制員傳遞給飛機師們的微下擊暴流預警或風切變預警，均包含首次相遇微下擊暴流或風切變事件的位置即跑道或離跑道入口兩端1海里2海里或3海里的地方以及計算風速差別的最大數值即最大強度。
  14. The idea is that the microburst or windshear alerts passed by the air traffic controllers to the pilots should include the location ( i. e. runway or 1, 2 or 3 nautical miles ( nm ) from runway threshold ) of the first encounter of the microburst or windshear event ( i. e. first encounter ) and the maximum value of the computed wind speed difference ( i. e. maximum intensity )

    這準則的構思是，所有經航空交通管制員傳遞給飛機師們的微下擊暴流預警或風切變預警，均包含首次相遇微下擊暴流或風切變事件的位置即跑道或離跑道入口兩端1海里、 2海里或3海里的地方以及計算風速差別的最大數值即最大強度。
  15. This simplifies the alerting of windshear when more than one occurrence of microburst or windshear is detected over the same approach or departure corridor

    當在同一進場或離場航道上出現多個微下擊暴流或風切變事件時，上述的準則能夠簡化風切變的預警。
  16. The first microburst in red band - aid shape detected by the tdwr in hong kong on 21 august 1996 when an area of thunderstorms affected the airport figure 3 : the first lidar image captured on 3 july 2002, showing the wind flow around the airport under fine weather

    一九九六年八月二十一日機場多普勒天氣雷達第一次探測到微下擊暴流紅色膠布形狀的地方，當時有一個雷暴區域影響著機場。
  17. As an example, under the windshear conditions depicted in the figure below where there is a windshear event of 15kt at 3 mile final and a microburst event of 30kt at 1 mile final, the consolidated windshear alert based on the first encounter, maximum intensity principle will be

    下圖例子顯示跑道進場3海里處出現了15海里小時風切變的事件，於1海里處同時出現- 30海里小時的微下擊暴流。根據"首次相遇位置最大強度"的準則，風切變預警應為：
