  1. On the other hand, it is indicated that the velocity field consists of a depth - independent inertial oscillation and a time - mean shear flow, which can be obtained by subtracting the inertial oscillations time mean in one inertial period. the hodograph of the velocity vector of time - mean flow at the different depths consists of a ekman spiral, and the surface velocity is 30. 3 ? to the right of the wind

    一維模式的流場結果表明，混合層中的流場是由慣性波動與時間平均流兩部分疊加而成，且通過時間平均消去慣性波動后得到平均流，其不同深度的流速矢量構成一ekman螺旋，表層流速矢量相對風向右偏了30 . 3 』 。
  2. The wind loading of a tracking radar antenna, for example, results from a mean velocity component that varies with time plus superimposed random gusts

    例如跟蹤雷達天線的風力負載是由一個隨時間變化的平均速度成分與迭加的隨機陣風組成的。
  3. A study on the relationship between friction wind velocity and mean wind velocity

    摩阻風速與平均風速的轉化關系研究
  4. The factors, especially the interval, that affect the statistic mean wind velocity are expatiated. then the effects on the power spectrum of pulsating wind pressure as well as on the dynamic response of the structure under wind loads are analyzed by means of monte carlo method when the square item of pulsating wind velocity is ignored

    在分析了平均時距對統計平均風速影響的基礎上，進而以結構的可靠度為指標利用montecarlo方法分析了當平均時距比較大時，脈動風速平方項對脈動風壓功率譜的影響。
  5. The disturbance located at inner region and near eyewall intensifying corresponds to the growth of amplitude of typhoon maximum tangential velocity with shorter period and the opposite is true. the weakening role of periphery disturbance intensity drop in typhoon maximum tangential wind reduces iv rossby obviously and the mean tangential wind display a strong vibrational characteristic for the periphery disturbance intensity growth

    臺風內核區和眼壁附近擾動的減弱（加強）使臺風最大切向風速的增幅減小（增大） ，且強度增強，風速變化的震蕩性加強，震蕩的周期縮短；強度減弱，風速變化的震蕩性減弱，震蕩的周期加長。
  6. The smaller convective patch corresponds to slight changes of maximum mean wind speed and the larger convective patch corresponds to the waves amplifying, the intensity of the inward propagation of vorticity strengthening distinctly, the amplitude of velocity change increasing and the period longing

    初始擾動尺度減小，渦旋rossby波減弱，對tc強度增強作用減弱；擾動尺度增大，波動增強，向內傳播的渦量顯著增大，但轉化為渦量帶現象變化不大，風速變化的震蕩性增強。
  7. This paper calculated the maximum mean velocity of wind and correspondences fluctuating wind continuous chart in duration of 100 years using greatest table sequence record in 10 minutes every month ( 3 ~ 5years ) in the basis of service life of the designed bridge and more probability

    本文從實際風速時程記錄開始，利用短期（ 3 5年）連續的10分鐘月最大時程記錄，在一定保證率下，按照小樣本推算極值的方法，推算100年一遇的平均風速以及在此基礎上的脈動風時程。
