摘　　要：全球—区域一体化预测系统(GRIST)是近年来我国模式开发团队独立设计、自主研发的新一代非结构化网格天气—气候一体化模式系统。该模式采用标准化、模块化的软件体系结构,具有静力—非静力一体化模拟、分辨率灵活可调、多物理包配置灵活可选等特点,可满足天气预报至长期气候模拟等不同时空尺度预测模拟需求。模式框架系统包括基础设施支撑层和模式运行层,外延功能包括前处理层和数据诊断层。每层中的模块都具有灵活的功能设计。初步应用表明,GRIST模式能够兼顾天气和气候模式运行的需求特点,是对天气—气候一体化模式研发的有力实践。GRIST(Global-Regional Integrated Forecast System)is a next-generation unstructured-grid unified weather-climate modeling system,independently designed and developed by Chinese model development team during recent years.The model adopts a standardized and modular software architecture.It has the features such as unified hydrostatic and nonhydrostatic modeling,flexible and adjustable resolution,and multiple physical packages.Therefore,it can satisfy the computing demands of various spatial and temporal scales,ranging from weather forecasts to long-term climate simulations.The model framework system consists of the infrastructure layer and the model operating layer,and the epitaxial function includes the pre-processing layer and the data diagnosic layer.The modules in each layer have flexible design functions.The preliminary application of the modeling system shows that GRIST can meet the operational needs both from weather modeling and from climate modeling,demonstrating a forceful implementation of unified weather-climate model development.
