解釋
雷達測風系統-
It was the first trial to employ the newly equipped migration data acquisition and analysis system for the scanning entomological radar and, a twin light - trap developed in china for, systematic long - term observations of migration of the beet armyworm spodoptera exigua, beet webworm loxostege sticticalis and cotton bollworm helicoverpa armigera in northern china the study provided direct evidence for the migration of 5 ". exigua in china, many parameters of migratory behaviour of the three species of insects, a better understanding of the relationship between migratory behaviour and wind or temperature field. the results enriched the theory of migration and provided new scientific knowledge for pest management in china
本研究初步闡明了我國華北地區空中昆蟲群落結構，首次使用我國自行研製的掃描昆蟲雷達的數字化數據採集及分析系統，及價廉、高效的姊妹燈誘蟲法對華北地區甜菜夜蛾spodopteraexigua 、草地螟loxostegesticticalis和棉鈴蟲helicoverpaarmigera的遷飛進行了長期系統地觀測，得到了甜菜夜蛾在我國北方遷飛的直接證據，三種害蟲遷飛行為的若干參數，認識了昆蟲遷飛行為與風溫場的關系，豐富了昆蟲遷飛理論，為我國害蟲的治理提供了科學依據。 -
This system also includes an on - line information service through which airline companies can retrieve flight documentation including forecast charts of en - route significant weather and wind temperature data issued by the world area forecast centres at london and washington, weather forecasts for departure, destination and alternate aerodromes, as well as the latest meteorological information of weather radar and satellite images, aerodrome warnings, tropical cyclone information, etc. weather briefings are provided via telephone or video conferencing equipment to flight crew members on request
該系統也包括一在線資料服務，航空公司可透過此服務提取包括由倫敦及華盛頓世界航空區域預報中心發放的航路上重要天氣及風/溫度資料的預報圖、起飛、目的地及備降機場天氣預報的飛行氣象文件。此外，航空公司亦可提取最新的氣象資料包括天氣雷達圖像、衛星雲圖、機場天氣警報及熱帶氣旋資料等。如有需要，航空預報員可以透過電話或視像會議系統向飛行人員作天氣簡報。 -
In addition, airway winds, which are essentially grid - point wind and temperature data over the south china sea for 15 flight levels between 10, 000 and 43, 000 ft, are disseminated to the radar data processing and display system ( rdpds ) of the cad for calculation of the expected arrival time of aircraft at check points
除此之外，氣象數據處理系統將飛機航道風的數據傳送至民航處的雷達數據處理及顯示系統，這些數據是風和溫度的網格點值，其水平范圍覆蓋南海，垂直范圍是由10 ， 000至43 ， 000尺之間的15個飛行高度；以上資料可用來計算航機抵達各定位點的時間。 -

Lastly radar wind field and radar humility field are assimilated in the mm5 4d variational assimilation system
最後把雷達風場和雷達濕度場同化到mm5四維變分同化系統中。 -
Miss sharon lau and mr. c. m. shun, who were responsible for the windshear and turbulence warning system wtws and terminal doppler weather radar tdwr respectively, talked on the observation of terrain - induced windshear at the hkia based on data collected by the tdwr, pilot reports and wind recordings on commercial aircraft
分別負責風切變及湍流警報系統wtws及機埸多普勒天氣雷達tdwr的劉心怡小姐及岑智明先生講述根據從tdwr資料機師報告及飛機上紀錄的風速風向而觀察到由地形引起的風切變。 -
The assimilation experimentation results indicate that after assimilating radar wind field of small spatial scale, mesoscale and small - scale precipitation prediction can be improved and mesoscale and small - scale information which ca n ' t appear by tradition datum can be gained, which is valuable to analyze the mesoscale and small - scale system structure ; the effect assimilating radar humidity field is n ' t obvious, which is perhaps correlation with precipitation types and assimilating time. the results also show that adding radar humidity field to initial condition at initial time can supply the gap of the regular data in reflecting the mesoscale and small - scale systems, strengthen the humidity in the initial field, and eventually help to improve precipitation. the experiment of assimilating radar wind field and radar humility field at the same time shows that vapor transportation and local vapor divergence play more significant role in causing excessively heavy rain than only high wet center
同化試驗結果表明：同化空間解析度很高的雷達風場后，能改善中小尺度降水的預報效果，並且能夠得到常規觀測資料所不能得到的中小尺度信息，對分析中小尺度系統結構具有重要意義；同化雷達濕度場效果不明顯，可能與降水類型和同化時刻有關；而直接在初始時刻加入雷達濕度場，補充了常規資料在反映中小尺度系統方面的不足，增強了初始場中的水汽，有利於降水量的增加；同時同化雷達風場和雷達濕度場的試驗表明，水汽的輸送和局地的水汽輻合對于產生特大暴雨的貢獻遠大於僅有高濕中心的貢獻。
