中文拼音 [guōdùqiángpò]
渦度強迫
英文
vorticity forcing-
In the second part of the paper, with employing the game reanalysis data and on the basis of the theories of the baroclinic vorticity development, this paper inferred from the dynamic analysis that the horizontal vorticity can represent the baroclinic intensity of the large - scale atmosphere, and the conversion of the horizontal vorticity converting into the vertical vorticity is actually the phenomenon that the horizontal vorticity flux of the summer monsoon owning the striking longitudinal - direction vertical structure and the strong baroclinicity, influence on the horizontal movement of the atmosphere
在第二部分，基於第一部分的結果，本文在斜壓渦度發展理論的基礎上，用在我國季風區具有更高準確性的game再分析資料，討論分析了能代表大尺度大氣斜壓性強度的水平渦度在向垂直渦度轉化的情況，說明了此轉化就是具有明顯經向垂直結構特徵和強斜壓性的夏季風環流圈將其經向垂直剖面上的渦旋通量強迫於水平運動的現象。The phenomena of initial disturbance vorticity translating into spiral bands is most evidently for it locating at the periphery of radius of maximum wind ( rmw ), near rmw next and the spiral bands vanish when it is positioned in the inner core region. indicating that the farther the distance from the tc center, the more distinctly the spiral bands and the opposite is true
初始圓形擾動渦度場轉化為螺旋臂渦量帶的現象是初始擾動位於渦旋最大風速半徑（ rmw ）外圍最顯著，其次是rmw附近，當擾動位於渦旋內核區時幾乎沒有螺旋臂結構形態出現，表明，初始擾動離tc中心越遠，其強迫渦旋rossby波形成的螺旋帶結構越明顯，反之越弱。Using a forced dissipative nondivergent nonlinear barotropic vorticity equation and by means of various schemes, we did simulation experiment and get its numerical solution
從強迫耗散無輻散正壓渦度方程出發，用不同方案模擬試驗得到它的數值解，它與已經導得解析解的特徵較為一致。Firstly, the airfoil ' s classic flutter ( at small attack angle ), stall flutter ( near the static stall angle ) and response ( at large attack angle ) are analyzed. it is found from the numerical results that " lock - in " will occur at certain freestream velocity range near the static stall angle, where the frequency of the vortex will be equal to the natural frequency and the flutter has the characteristic of self - induced oscillation. when the attack angle is far from the static stall angle, the vortex will have its own frequency, which differs from the natural frequency, and the flutter has the characteristic of forced oscillation
首先研究了二維翼型的古典顫振（小攻角） 、失速顫振（失速攻角）和動力響應問題（大攻角） ，得到以下結論：在靜態失速攻角附近的一定來流速度范圍內，分離渦會發生頻率鎖定現象，分離流的頻率與固有頻率趨于相同，這時的振動呈現自激振動的特點；遠離失速攻角時分離流頻率則擺脫固有頻率的影響，此時的振動具有強迫振動的特點。Then numerical experiments on forcing dissipation and heating response of dipole ( unipole ) are carried out using global spectral model of quasi - geostrophic barotropic vorticity equation. for every experiment model integration is run for 90 days on the condition of three waves quasi - resonance. the results are given as follows : ( 1 ) under the effects of basic flow intensity and dipole ( unipole ) forcing source, there exist strong interaction among the three planetary waves, and there also exist quasi - two - week and intra - seasonal oscillation of the three planetary waves
然後，用數值試驗的方法，應用強迫耗散準地轉正壓渦度方程的全球譜模式，並在方程中考慮了偶（單）極子的熱力強迫作用，在三個行星波準共振的條件下，模式共積分90d ，得出： （ 1 ）在基本氣流強度和偶（單）極強迫熱源的共同作用下，三個行星波之間存在很強的波?波相互作用，且波動振蕩呈現準雙周和季節內振蕩。分享友人
