粗網格-
In this approach, the full nonlinear system is solved on a coarse grid. the nonlinearities are expanded about the coarse grid solution, and the resulting linear system is solved on a fine grid
這些演算法的特點是僅在粗網格上進行非線性問題的計算，而在所需要求解的細網格上只進行線性問題的計算。 -
The number of the grid in the focast area of the coarse nest is 65 71 while that of the fine nest is 73 82
預報區域格點數粗網格為65 71 ，細網格為73 82 。 -
The cascadic multigrid method has been shown to be one of the most efficient iterative techniques for solving large boundary value problems, the main advantage of which is coarse - grid - correction free, and as a result it can be viewed as a one - way multigrid method
瀑布型多重網格法是求解大型邊值問題的一種有效的迭代解法，其主要優點是不要求粗網格校正，故又稱單步多重網格法。 -
Grell scheme can simulate pw more accurate than others for coarse grid of mm5 and pw simulation of bm scheme is less accurate than others for fine grid of mm5. 3, the initial humidity fields reanalyzed by using gps pw can obviously improve its capability in revealing the water vapor distribution, which can result in restraining pw prediction bias during the earlier period of model integration so as to improve pw prediction
3 、用gps測量的可降水量資料調整mm5模式濕度初始場可明顯增強模式初始場描述水汽分佈的能力，使其對可降水量的描述誤差明顯減小，有利於模式初始場更好地反映出水汽分佈的局地特徵，從而有效地控制模式積分初期對可降水量的預報誤差。 -
Products from these global models are generally adequate for forecasting large - scale weather systems such as surges of the winter monsoon. however, limited by the coarse resolution of the data received, the grid point information is inadequate for resolving smaller scale features associated with inclement weather
在預報冬季季候風寒潮這類大尺度天氣系統時，上述資料一般來說是足夠的，但是對于中小尺度的惡劣天氣系統而言，資料的分解度就不夠精細了。 -
The researching method is, firstly, to create a flow field model which is testified to be reliable on a large area, and to research the variations of discharge entering and out - flowing from hangzhou bay ; secondly, to simulate the discharge variation of main interest area near the bridge axis with a denser grid in a subarea of the coarse model
研究方法是首先建立大范圍的可靠適用的流場數值模型，研究進出杭州灣的流量變化；然後對感興趣的區域嵌套加密網格，利用橋墩物理模型測定的等效底摩阻系數，研究建橋前後在橋軸線上的流速、流量變化。 -
A complicated model has been setted up to simulate the sodium flow in hot and cold plenum under normal condition and reactor scram of cefr, using fine grid to simulate the reactor internals and important equipments. this slove the problem that the simulation grids are very coarse in the precedeable work, and the accuracy and reliability of the simulation are improved. 4
對cefr的額定工況和全廠斷電工況下的堆內過程進行了復雜的數學建模和分析，使用了精細的六面體網格，對堆內構件和重要的設備進行了三維的數值分析，克服了以往數值模擬中網格過于粗糙的缺點，使數值分析的準確性和可信度大大提高； 4
