摘要

大气数值模式在实际天气预报和通过研究提高我们对大气动力学的认识方面起着至关重要的作用。最大限度地提高它们的准确性至关重要。在大气模型中使用>O7通量格式在很大程度上是没有记录的，没有研究将O3-17通量与形式保持精度的高阶插值、压力梯度/散度和亚网格尺度(SGS)湍流通量考虑在内。高阶数值近似可以减少截断、幅度和相位误差，并有可能提高模型精度和有效分辨率。

Nonlinear diffusion-limited 2D colliding plume simulations with very high order numerical approximations

Atmospheric numerical models play a crucial role in operational weather forecasting, as well as improving our understanding of atmospheric dynamics via research studies. Maximising their accuracy is of paramount importance. Use of >O7 flux schemes in atmospheric models is largely undocumented, with no studies considering O3–17 fluxes with formal accuracy-preserving high order interpolation, pressure gradient / divergence, and subgrid-scale (SGS) turbulent fluxes. Higher order numerical approximations can reduce truncation, amplitude and phase errors, and potentially improve model accuracy and effective resolution.

期刊介绍： The Quarterly Journal of the Royal Meteorological Society is a journal published by the Royal Meteorological Society. It aims to communicate and document new research in the atmospheric sciences and related fields. The journal is considered one of the leading publications in meteorology worldwide. It accepts articles, comprehensive review articles, and comments on published papers. It is published eight times a year, with additional special issues. The Quarterly Journal has a wide readership of scientists in the atmospheric and related fields. It is indexed and abstracted in various databases, including Advanced Polymers Abstracts, Agricultural Engineering Abstracts, CAB Abstracts, CABDirect, COMPENDEX, CSA Civil Engineering Abstracts, Earthquake Engineering Abstracts, Engineered Materials Abstracts, Science Citation Index, SCOPUS, Web of Science, and more.
