In this paper, we describe the design of the coupling library, Jcup, and report its various applications, including the coupling between global atmospheric and oceanic models of different grid systems. Jcup is a software library mainly focused on weather/climate models and was developed for coupling the components of various models. Jcup has the flexibility to be applied to an unspecified number of components of earth system models. To achieve a high level of safety and versatility, we classified the processes of the general coupling software into processes that change the value of the data and those that do not and placed the former outside of the program and under the control of the user. Consequently, Jcup exhibits two features: (1) the correspondence relationship between grid indexes is used as input information, and (2) the user can implement an arbitrary interpolation code. Jcup was applied to atmosphere-ocean coupling, IO component coupling, and the coupling between the seismic model and structure model, and the validity and usefulness of the design were demonstrated.

耦合库Jcup3：其原理和应用

在本文中，我们描述了耦合库Jcup的设计，并报告了它的各种应用，包括不同网格系统的全球大气和海洋模型之间的耦合。Jcup是一个主要针对天气/气候模型的软件库，它是为耦合各种模型的组件而开发的。Jcup可以灵活地应用于未指定数量的地球系统模型的组件。为了实现高度的安全性和多功能性，我们将通用耦合软件的过程分为可改变数据值和不改变数据值的过程，并将前者置于程序之外并在用户的控制下。因此，Jcup具有两个特征：（1）网格索引之间的对应关系用作输入信息，（2）用户可以实现任意的内插代码。将Jcup应用于大气-海洋耦合，IO分量耦合以及地震模型与结构模型之间的耦合，论证了设计的有效性和实用性。
