Description

technical field [0001] The invention belongs to the field of earth system science and technology. Especially related to the coupling system C-Coupler of the earth system model. Background technique [0002] The Earth system is a complex system, an organic whole composed of the atmosphere, hydrosphere, land sphere (lithosphere, mantle, earth core) and biosphere (including humans). The Earth system model is a large-scale comprehensive calculation program of scientific tools for simulating and predicting complex behaviors and processes of the Earth system. It considers the atmosphere, hydrosphere, cryosphere, lithosphere, and biosphere of the earth system as an interacting whole, and determines its parameters based on the mathematical equations established by the dynamic, physical, chemical, and biological processes in the earth system. The properties of each part constitute the mathematical and physical model of the earth system, and then use numerical methods to solve it an...

AI Technical Summary

Problems solved by technology

[0005] 2. In terms of versatility: does not support two-way regional nested coupling, does not support online collection of component models (such as the average of multiple atmospheric model data)

[0008] 5. In terms of numerical coupling function: it does not support the coupling of 3D data, only supports the coupling of 2D data

[0009] 6. In terms of computing performance: Although parallel communication between multiple processes in the component mode and multiple processes in the coupler is realized, asynchronous communication is not realized. In addition, the way the coupler centrally controls the coupling of the component mode will lead to redundant communication

[0013] 3. In terms of computing performance: Although the direct coupling between component modes will not lead to redundant communication, the coupling computing performance depends on the coupling interface of each component mode, and it is difficult to optimize the overall computing performance

With the increasing number of components and models of the earth system model coupling, as well as the development of requirements such as two-way nested coupling and online collection, the above shortcomings will limit the application of related work
