From the numerical modeling results, it can be found that there is a clockwise gyre in the middle part of bohai sea, whether in wintertime or in summertime. in summer, the clockwise gyre corresponding to the high - temperature and low - density center in the middle bohai sea is mainly dominated by the density circulation. and in winter, it is mainly dominated by the wind stress curl
通過數值模擬結果發現,在渤海中部,無論冬季還是夏季,都存在一個順時針的渦旋運動,夏季,對應于渤海中部的高溫低密中心,其流場主體部分呈順時渤海冬夏季環流特徵及變異的初步研究針向旋轉,這主要是密度環流占優的結果,而冬季的順時針向的旋轉,主要是海面風應力旋度影響的結果。By performing fourier transformation, the relationship between the turbulent intensity of the particle and that of the carrier fluid was obtained which makes clear that particle size, specific gravity, velocity gradient, and the characteristic frequency of energy - containing eddies are four basic influencing parameters. it is proven theoretically that under certain conditions, the stream - wise and transverse particle turbulent intensities exceed those of the carrier fluid. based on the equations of two - phase flow, the presence of fine sediment suspension is shown to attenuate the turbulent intensity of the water
通過對細小顆粒在剪切流場中運動方程的fourier分析,得到了顆粒脈動強度和流體脈動強度之間的定量關系,表明顆粒粒徑、顆粒密度、流速梯度以及紊動場含能旋渦的特徵頻率是影響顆粒脈動強度的主要因素,首次從理論上證明了在一定條件下,顆粒在縱、垂向的脈動強度均會超過相應的流體脈動強度,為已有的實測資料提供了合理的解釋。Working carefully in fast - flowing eddies created by crumpled steel and concrete, divers with only a foot of visibility had located some of the vehicles that were hurled into the river when the 40 - year - old bridge gave way during wednesday ' s evening rush hour in minneapolis
星期三傍晚下班交通高峰時期,密西西比河上方一座年逾40的橋轟然倒塌,斷橋的鋼筋混凝土掉入水中激起很多旋渦,水下救生員在能見度只有一英尺的水中經過認真摸索找到了一些被捲入急流旋渦中的汽車的位置The salinity distribution characteristics are the high - salinity in the bohai bay and the low - salinity in the boahi strait. the density distribution shows that there is a large cyclonic density circulation in bohai sea and it is likely to exist some density current gyre in the middle part of the bohai sea. in winter the saddle - like pattern of the bohai sea temperature and salinity shows that the circulation structure is much complexer than the previous research results
密度分佈表明:夏季渤海灣口已經由以前的低密度中心變為現在的高密度中心,相應的環流結構也必會發生大的變化;夏季渤海中部會存在一個反氣旋式的密度環流,並在局部可能存在多個密度流渦環;冬季渤海「馬鞍狀」溫鹽結構反映其密度環流結構要比以往研究結果復雜得多。A transverse secondary circulation is produced by the coupling of high and low jets, while the sinking branch of the secondary circulation providing the dynamic conditions for the dry intrusion air. during the period of the heavy rain process, dry intrusion descends southward along the intense constant potential temperature lines, which promotes the lower cyclone. in addition, the pouring of upper - level dry air not only decreases ground temperature behind the front but also increases surface pressure and velocity
由於高、低空急流耦合,在高空急流中心左側產生的下沉運動和高空急流中心右側、低空急流左側產生的上升運動在鋒面上形成一次級環流,次級環流的下沉支運動為對流層高層干空氣和高位渦的下傳提供了動力條件;進一步研究發現,干侵入沿相當位溫密集帶向南向下伸展,引起對流層低層氣旋性渦度的發展;此外,高層乾冷空氣向下注入,導致地面溫度降低、氣壓升高、風速加大、低層輻合增強、上升速度加大,從而促進了新的對流運動,引起降水增強。There are two evident cyclonic eddies whose centers lie at 34 n, 164 band 33 n, 176 e, and two evident anti - cyclonic eddies whose centers lie at 33 n, 175 e and 32 n, 162. 5 e. the result seems to suggest a causal relation between the formation, evolution and disappearance of the eddy and the kuroshio meander path
其中比較明顯的渦旋包括中心位置分別位於34on , 164oe和33 「 n , 176 「 e附近的兩個氣旋渦和中心位置在33on , 175oe和32on , 162 . 5oe的兩個反氣旋渦。本文認為渦旋的形成、發展與消亡與黑潮路徑的彎曲程度以及主軸流速的大小有著密切的因果關系。The main conclusions show as following : 1 the effects of propagating vortex rossby waves on tc intensity change are relative closely to the position, the size and intensity of the initial disturbance
主要結果可歸納如下: 1渦旋rossby波傳播對熱帶氣旋強度變化的影響,與初始擾動相對渦旋中心的位置、初始擾動尺度大小及強度等關系密切。分享友人
