全球气候模式

气候模式是由描述物理、流体运动和化学的基本定律的微分方程组所构成的系统。为了运行一个模式，科学家将地球划分成许多三维网格，应用这些基本方程，以及评价结果。大气模式在每个网格里计算风、热传输、辐射、相对湿度和地表水文，还要评估与相邻网格间的相互作用。风、热传输和其他变量仅仅被用来计算一个最终结果，因此它们不被要求对应真实世界里的情况。在有些数值方案里虚拟的变量被使用。

大气环流模式（General Circulation Model，GCM）是描述行星大气或海洋的数学模型。它是基于旋转球体的纳维－斯托克斯方程，包括热力学项来反映很多能量源（比如辐射、潜热）。这些方程序用于模拟地球大气或海洋的复杂计算机进程的基础。大气和海洋环流模式（AGCM和OGCM）、海冰、陆地表面过程是全球气候模式（Global Climate Model）的关键成分。大气环流模式和全球气候模式被广泛的应用与天气预报、理解气候、预测气候变化等方面。用于研究十年到百年时间尺度的气候的模式最早是由真锅淑郎和科克·布莱恩在位于普林斯顿的地球物理流体动力学实验室里创造的。这些需要大量计算的数值模式集成了流体力学、化学、有时还有生物学的各类方程。

A general circulation model (GCM) is a type of climate model. It employs a mathematical model of the general circulation of a planetary atmosphere or ocean. It uses the Navier–Stokes equations on a rotating sphere with thermodynamic terms for various energy sources (radiation, latent heat). These equations are the basis for computer programs used to simulate the Earth's atmosphere or oceans. Atmospheric and oceanic GCMs (AGCM and OGCM) are key components along with sea ice and land-surface components.
