The proposed research consist of the development of modelling techniques for advanced simulations of physical phenomena taking place in the Earth's Atmosphere. In particular, the research will contribute to the improvement of unstructured meshes based nonhydrostatic models for limited area geophysical flows which can alleviate limitations of regular grids traditionally used for weather forecasts. Main feature of the research will be the multi-scale approach that would encompass a large number of atmospheric phenomena. A particular aspects of new developments will include high performance computing and new algorithmic features aiming at increasing efficiency of numerical simulations.

拟议的研究包括发展模拟技术，以模拟地球大气中发生的物理现象。特别是，该研究将有助于改进基于非结构化网格的有限区域地球物理流动非流体静力模型，从而减轻传统用于天气预报的规则网格的局限性。这项研究的主要特点将是采用涵盖大量大气现象的多尺度方法。新发展的一个特定方面将包括高性能计算和旨在提高数值模拟效率的新算法特征。
