Abstract

This chapter reviews the history and status of dynamical core model development efforts in China. In summary, the entire chain of model development, from basic guiding principles and algorithm design through to model implementation and evaluation, is fully covered by the Chinese modeling community. Ten modern global models that have contributed to dynamical core development are described in detail. Different modeling groups have made different choices and implemented various strategies for model development according to their specific objectives and areas of expertise. It is argued here that the process of model development should, in addition to improving model performance, continuously boost productivity in both the industrial and academic sectors. Three major trends (higher model resolution, earth system approach, unified weather, and climate modeling) that may affect the design and development of dynamical cores are identified in the summary section.

Notes

  1. 1.

    Because the creation of a dynamical core is for practical weather and climate simulations, it would be of less interest to discuss the dynamical core independent from its host model. Thus, the terms “dynamical core” and “model” are loosely interchangeable in this chapter.

  2. 2.

    This operational center was reorganized and renamed the CMA Earth System Modeling and Prediction Center (CEMC) on 30th September 2021.
