该报告描述了由宾夕法尼亚州立大学和美国国家大气研究中心（NCAR）开发的一个有限区域的、流体静力的原始方程数值模式。该模式被称为宾夕法尼亚州立大学/美国国家大气研究中心中尺度模式第4版，即MM4。报告记录了连续模式方程及其有限差分模拟、水平和垂直网格结构、侧向边界条件以及模式中物理过程的参数化。这些过程包括热量、水汽和动量的地表通量，这些量在行星边界层和自由大气中的湍流输送，水平扩散，以及对流云和非对流云中潜热的释放。报告还提供了其他报告和出版物的参考文献，这些文献记录了该模拟系统以及该系统在大气现象模拟中的应用。
The report describes a limited-area, hydrostatic, primitive equation numerical model developed by the Pennsylvania State University and the National Center for Atmospheric Research (NCAR). The model is known as the Penn State/NCAR Mesoscale Model, Version 4, or MM4. The report documents the continuous-model equations and their finite-difference analogs, the horizontal and vertical grid structures, the lateral boundary conditions, and the parameterization of physical processes in the model. These processes include surface fluxes of heat, moisture and momentum, the turbulent transport of these quantities in the planetary boundary layer and the free atmosphere, horizontal diffusion, and the release of latent heat in convective and nonconvective clouds. The report also provides references to other reports and publications that document the modeling system and applications of the system to the simulation of atmospheric phenomena.
