convergence temperature 解釋
冰點測定溫度的近似值
  • convergence : n. 1. 聚合，會聚，輻輳，匯合。2. 集合點；【數、物】收斂；【生物學】趨同（現象）。
  • temperature : n. 1. 溫度，氣溫。2. 體溫。3. 〈口語〉發燒，高燒。
  1. The diagnostic analysis for the sandstorm process on the base of height, temperature, pressure and wind etc output from the model shows that the upper cold trough, low - level wind shear, surface cold anticyclonic ridge, mesoscale cyclone and cold front are the main synoptic systems, surface cold anticyclonic ridge and cold front provide condition of wind force to occurrence of the sandstorm weather, the strong mesoscale cyclone before front makes pressure gradient before and after cold front obviously strengthen, moreover, and it increases obviously the temperature of the controlled area, as a result, the updraft movement caused by convergence before front strengthens

    500hpa強鋒區、 700hpa切變和鋒前中尺度系統的強弱及位置變化是沙塵暴天氣發生發展到減弱的直接原因。地面冷高壓、地面氣旋及冷鋒是造成本次沙塵暴天氣的主要地面天氣系統。地面冷高壓及冷鋒為沙塵暴天氣的發生提供了風力條件，而中尺度氣旋使冷鋒前後氣壓梯度明顯增強外，又使所控制的區域增溫明顯，使鋒前輻合上升運動加強，為沙塵暴天氣的發生提供了熱、動力條件。
  2. The results of numerical experiments, using the four - dimensional variational data assimilation system of the nonhydrostatic mesoscale model mm5, show that : the tangent linear model and adjoint model conducted by keeping the " on - off " switches the same as the basic state, can provide a good approximation of the first - order information to the nlm perturbation and a good descent direction for the minimization procedure ; switching on and off at every other time step in the kuo cumulus parameterization scheme do n ' t impact the convergence rate of cost function ; the existence of the switches do n ' t impact improvement to the mm5 model rainfall prediction because that not only specific humidity, but also wind, temperature and pressure are assimilated into the model

    非靜力中尺度數值模式mm5的四維變分資料同化系統進行的數值試驗結果表明： 「開關」變量保持與基態一致，所構造的切向線性模式能夠提供關于非線性模式擾動的一階近似，伴隨模式所計算的梯度值能夠為最小化過程提供較好的下降方向；郭氏降水參數化方案中對流每隔一個積分步的交替發生並不影響目標函數最小化的收斂速度； 「開關」變量的存在也不影響將風、溫度、氣壓和比濕結合起來同化對mm5降水預報準確性的提高。
  3. In the paper, stratified flows with combined temperature and salinity are investigated on unstructured computational grids. first, unstructured, collocated finite volume method for navier - stokes equations is developed under the philosophy of generality. the pressure - velocity coupling is treated using simple - like algorithm and explicit correction step technique is applied to speed the convergence rate

    本文從該類研究的難點入手，首先，採用單元中心的有限體積法開發了通用性強，易擴展的非結構同位網格數學模型求解n - s方程，壓力校正採用simple （ simplec ）演算法，並採用顯式校正步法（ explicitcorrectionstep ）對simplec演算法進行了顯式校正。
  4. Low temperature of the convergence point of the melting materials, making the incomplete melting during the process

    4熔融材料合流部分溫度太低，使合流時未能充分熔合。
