中尺度大气过程的2.5维方程组的模拟和数值逼近
Modelling and numerical approximation of a 2.5D set of equations for mesoscale atmospheric processes
摘要：
三维无粘大气原始方程组在一个水平方向上通过间断Galerkin离散降维。由此产生的模型是一个二维系统的平衡法，其中的源项取决于分层程序和耦合通量的选择，这是建立在逆风的考虑。“2.5D”系统采用基于磁通限制器中心法的WENO-TVD格式离散。我们研究了四个与大气现象相关的测试案例，以分析模型的物理有效性。
英文摘要：
The set of 3D inviscid primitive equations for the atmosphere is dimensionally reduced by a Discontinuous Galerkin discretization in one horizontal direction. The resulting model is a 2D system of balance laws where with a source term depending on the layering procedure and the choice of coupling fluxes, which is established in terms of upwind considerations. The "2.5D" system is discretized via a WENO-TVD scheme based in a flux limiter centered approach. We study four tests cases related to atmospheric phenomena to analyze the physical validity of the model.
