Abstract

The invention provides an unstructured grid meteorological numerical model calculation system, including an unstructured grid generation subsystem and a numerical simulation calculation subsystem, and the unstructured grid generation subsystem is used to generate the numerical simulation calculation subsystem. The required grid file, the numerical simulation calculation subsystem is used to call the grid file, and perform calculations based on the grid file. The invention has the beneficial effects of providing a non-structure grid meteorological numerical model calculation system, which provides basic technical support for improving the weather forecast level and climate forecast level of our country.

Description

technical field [0001] The invention relates to the technical field of meteorology, in particular to an unstructured grid meteorological numerical model calculation system. Background technique [0002] With the improvement of social and economic level and the development of science and technology, people's demand for timely and accurate weather forecast and climate prediction is increasingly strong, which depends on the development and perfection of meteorological numerical simulation system. Today's meteorological simulation system has gradually entered into multi-scale seamless forecasting, and its hallmark feature is that it needs to adapt to a computing environment with large data throughput, large calculation volume, and large-scale parallelization. Most of the existing meteorological numerical models are based on structured grids. The grids lack flexibility, and the algorithm is bound to the grid. Modifying the grid requires adjusting the corresponding calculation met...
