Climate models have been used as an important tool to quantitatively study climate variability and to predict or project climate change in the future. One of the most important pathways for development and improvement of climate system model is to increase the spatial resolution and improve the corresponding physical parameterization schemes,which is very important for understanding climate change and improving climate prediction skill. Based on a brief introduction of the importance of developing high-resolution global climate system model,a review of recent progresses in the development and application of high-resolution models was summarized. The paper also introduced the current situation and problems for the development and evaluation of high-resolution models and focused on the key scientific and technical bottlenecks which restrict the development of high-resolution models,including the development of dynamic framework of the high-resolution ocean and atmospheric models and massive high performance parallel computing,the improvement of the sub-grid physical parameterization scheme,and mesoscale air-sea interaction. Meanwhile,the scientific objects and experiments design of the international high resolution climate model intercomparison project (HiResMIP) of the coupled model intercomparison project phase 6(CMIP6) was introduced. Finally,we prospect the future developments and evaluations of high-resolution climate models in China was proposed.
