Abstract：The earth system models (ESMs) are the basic tools used for climate change research and unseamable weather forecasting. The coupler connects the components in the ESMs and is the key to integrating and the modular development of the ESMs. This paper presents a visualization of the coupler operation based on the C-Coupler2 developed in China. The visualization facilitates coupling construction and the coupling connections among components. The system allows visual display and construction of the C-Coupler2 coupling configuration file and an interactive display of the C-Coupler2 coupling connections among components. This improves the user friendliness of C-Coupler2 and makes C-Coupler2 the first autonomous coupler with visual support.
