    除提供本地的機場天氣預報外，天氣預報員並繪制航路上重要天氣預報圖，顯示十二小時后可能影響飛行航路地區之重要天氣，例如雷暴、臺風及晴空湍流等。
  2. The non - local turbulence parameterization, i. e., transilient theory was used in the host model mm4 to simulate the turbulent activities of the atmosphere

    在中尺度區域模式mm4的基礎上對其中的湍流參數化方法作了改進，嘗試用非局地閉合方法代替局地
  3. The viscid flux is discretized by second - order central difference scheme. baldwin - lomax turbulence model is implemented in navier - stokes flow solver. for steady - state calculations, a four - stage runge - kutta scheme with convergence acceleration techniques such as local - time stepping and implicit residual smoothing is used

    其中，定常計算中的時間推進採用四步runge ? kutta方法，並應用了當地時間步長、隱式殘值光順等加速收斂措施；非定常計算中的時間推進採用jameson的隱式雙時間方法。
  4. 3. a three - dimensional - acoustic doppler velocimeter has been used to measure the velocity and turbulence in a compound channel with vegetated and unvegetated flood - plains. particulary in the interface region between main channel and floodplain. the distribution in three coordinate directions of velocity and turbulence intensities and the renolds stresses are presented. the momentum transfer at the main channel flood - plain interface can be described as an apparent shear stress which can be quantified as a function of the local turbulence at the interface

    採用adv對灘地種樹前後灘槽交界區域的流速場進行了量測。分析了灘槽交界區域的垂線流速、紊動強度和雷諾應力的變化。將灘槽交界的動量傳遞描述為一表觀應力，這個表觀應力可以看作是交界面處的脈動函數並將其定量化。
  5. Using the program two and three - dimensional numerical simulation of wind flow around single or multiple buildings can be achieved and the detailed flow condition including wind velocities, pressures and time - average characteristics of turbulence can be obtained. in order to attain the required accuracy efficiently multi - layer local refinements can be carried out based on the initial division grid

    程序採用fortran語言編制，可實現二維和三維單體及群體建築的繞流風場的模擬計算，獲得建築繞流風速、表面風壓及湍流平均特性等數據；可通過對初始網格實施多層次的網格局部加密，以使風場解達到最終的精度要求。
  6. The ns solver is developed from euler equation code by adding viscous terms and two - equation turbulence models. in order to get a better result, the improved jameson second and forth artificial dissipation is used, the implicit residual averaging and local time step techniques are employed to accelerate the convergence processing

    本文是在歐拉方程求解器的基礎上，通過加入粘性（耗散）項，把流場的主控方程由歐拉方程（ euler ）改為ns方程，然後引入兩方程湍流模型，使其封閉。
