To serve the application and review of funding proposals in atmospheric numerical model development and promote further development of the discipline, we interpret the research directions and keywords of D0511 atmospheric numerical model development, a second-level application code of the atmospheric science discipline of the National Natural Science Foundation of China, are interpreted herein. The essence of atmospheric numerical model is to solve the numerical solution of partial differential equations using numerical algorithms based on physical or chemical processes. The development of atmospheric numerical models should be guided by tackling key core technologies to enhance China’s comprehensive international competitiveness.This paper reviews the setting background of D0511, the overall framework of the research directions and the keywords of D0511. As well as interpreting the specific considerations of the keywords. The paper analyzes and discusses the word frequency and research hotspots in different directions based on bibliometric methods and the Web of Science database. The use of the keywords is analyzed based on their applications in the recent two years. Suggestions on the choice and optimization of keywords are also put forward. The future setting of keywords should be in accordance with the updated basic guiding principles.
