[[File:Global Climate Model.png|thumb|right|350px|Climate models are systems of [[differential equation]]s based on the basic laws of [[physics]], [[Fluid dynamics|fluid motion]], and [[chemistry]]. To “run” a model, scientists divide the planet into a 3-dimensional grid, apply the basic equations, and evaluate the results. Atmospheric models calculate [[winds]], [[heat transfer]], [[radiation]], [[relative humidity]], and surface [[hydrology]] within each grid and evaluate interactions with neighboring points.]]
Numerical '''climate models''' use [[quantitative method]]s to simulate the interactions of the important drivers of climate, including [[Earth's atmosphere|atmosphere]], [[ocean]]s, [[land surface]] and [[cryosphere|ice]]. They are used for a variety of purposes from study of the dynamics of the climate system to projections of future [[climate]].

数值气候模型使用定量方法来模拟气候的重要驱动因素之间的相互作用，包括大气、海洋、陆地表面和冰。它们被用于从研究气候系统的动态到预测未来气候的各种目的。气候模型也可以是定性的(例如:。而不是数字)模型，以及对未来可能的叙述，主要是描述。
Quantitative climate models take account of incoming [[energy]] from the sun as short wave [[electromagnetic radiation]], chiefly [[Visible spectrum|visible]] and short-wave (near) [[infrared]], as well as outgoing long wave (far) [[infrared]] electromagnetic. An imbalance results in a [[First law of thermodynamics|change in temperature]].

定量气候模型考虑到来自太阳的入射能量为短波电磁辐射，主要是可见光和短波(近)红外线，以及外向长波(远)红外线电磁辐射。不平衡导致温度的变化。
Quantitative models vary in complexity:
* A simple [[radiant heat]] transfer model treats the earth as a single point and averages outgoing energy. This can be expanded vertically (radiative-convective models) and/or horizontally
* Finally, (coupled) atmosphere–ocean–[[sea ice]] [[global climate model]]s solve the full equations for mass and [[energy transfer]] and radiant exchange.
* Other types of modelling can be interlinked, such as [[land use]], in [[Earth system model|Earth System Models]], allowing researchers to predict the interaction between climate and [[ecosystems]].

==Box models==
[[File:Simple box model.png|thumb|upright=1|right| Schematic of a simple box model used to illustrate [[flux]]es in geochemical cycles, showing a source ''(Q)'', sink ''(S)'' and reservoir ''(M)'']]
Box models are simplified versions of complex systems, reducing them to boxes (or [[Thermodynamics#Instrumentation|reservoir]]s) linked by fluxes. The boxes are assumed to be mixed homogeneously. Within a given box, the concentration of any [[chemical species]] is therefore uniform. However, the abundance of a species within a given box may vary as a function of time due to the input to (or loss from) the box or due to the production, consumption or decay of this species within the box.

盒子模型是复杂系统的简化版本，将它们简化为通量连接的盒子(或水库)。假定这些盒子是均匀混合的。因此，在一个给定的盒子内，任何化学物质的浓度都是均匀的。然而，在一个给定的盒子内的一个物种的丰度可能会随着时间的变化而变化，这是由于盒子内的输入(或损失)或这个物种在盒子内的生产、消费或衰变所致。
Simple box models, i.e. box model with a small number of boxes whose properties (e.g. their volume) do not change with time, are often useful to derive analytical formulas describing the dynamics and steady-state abundance of a species. More complex box models are usually solved using numerical techniques.

The average emissivity of the earth is readily estimated from available data. The emissivities of terrestrial surfaces are all in the range of 0.96 to 0.99 (except for some small desert areas which may be as low as 0.7). Clouds, however, which cover about half of the earth's surface, have an average emissivity of about 0.5 (which must be reduced by the fourth power of the ratio of cloud absolute temperature to average earth absolute temperature) and an average cloud temperature of about . Taking all this properly into account results in an effective earth emissivity of about 0.64 (earth average temperature ).
地球的平均比辐射率很容易从现有数据中估计出来。陆地表面的放射系数均在0.96ー0.99之间(除少数小沙漠地区可能低至0.7)。然而，覆盖地球表面大约一半的云层，其平均发射率约为0.5(必须用云的绝对温度与地球平均绝对温度之比的四次方减少) ，而云的平均温度约为0.5。适当地考虑这些因素，得到的有效地球发射率约为0.64(地球平均温度)。
This simple model readily determines the effect of changes in solar output or change of earth albedo or effective earth emissivity on average earth temperature. It says nothing, however about what might cause these things to change. Zero-dimensional models do not address the temperature distribution on the earth or the factors that move energy about the earth.

== GCMs (global climate models or general circulation models) ==
{{Main|General circulation model}}
General Circulation Models (GCMs) discretise the equations for fluid motion and energy transfer and integrate these over time. Unlike simpler models, GCMs divide the atmosphere and/or oceans into grids of discrete "cells", which represent computational units. Unlike simpler models which make mixing assumptions, processes internal to a cell—such as convection—that occur on scales too small to be resolved directly are parameterised at the cell level, while other functions govern the interface between cells.

Atmospheric models calculate [[winds]], [[heat transfer]], [[radiation]], [[relative humidity]], and surface [[hydrology]] within each grid and evaluate interactions with neighboring points.]]
Numerical '''climate models''' use [[quantitative method]]s to simulate the interactions of the important drivers of climate, including [[Earth's atmosphere|atmosphere]], [[ocean]]s, [[land surface]] and [[cryosphere|ice]].

数值气候模型使用定量方法来模拟气候的重要驱动因素之间的相互作用，包括大气、海洋、陆地表面和冰。它们被用于从研究气候系统的动态到预测未来气候的各种目的。气候模型也可以是定性的(例如:。而不是数字)模型，以及对未来可能的叙述，主要是描述。
Quantitative climate models take account of incoming [[energy]] from the sun as short wave [[electromagnetic radiation]], chiefly [[Visible spectrum|visible]] and short-wave (near) [[infrared]], as well as outgoing long wave (far) [[infrared]] electromagnetic. An imbalance results in a [[First law of thermodynamics|change in temperature]].

定量气候模型考虑到来自太阳的入射能量为短波电磁辐射，主要是可见光和短波(近)红外线，以及外向长波(远)红外线电磁辐射。不平衡导致温度的变化。
Quantitative models vary in complexity:
* A simple [[radiant heat]] transfer model treats the earth as a single point and averages outgoing energy. This can be expanded vertically (radiative-convective models) and/or horizontally
* Finally, (coupled) atmosphere–ocean–[[sea ice]] [[global climate model]]s solve the full equations for mass and [[energy transfer]] and radiant exchange.
* Other types of modelling can be interlinked, such as [[land use]], in [[Earth system model|Earth System Models]], allowing researchers to predict the interaction between climate and [[ecosystems]].

==Box models==
[[File:Simple box model.png|thumb|upright=1|right| Schematic of a simple box model used to illustrate [[flux]]es in geochemical cycles, showing a source ''(Q)'', sink ''(S)'' and reservoir ''(M)'']]
Box models are simplified versions of complex systems, reducing them to boxes (or [[Thermodynamics#Instrumentation|reservoir]]s) linked by fluxes. The boxes are assumed to be mixed homogeneously. Within a given box, the concentration of any [[chemical species]] is therefore uniform. However, the abundance of a species within a given box may vary as a function of time due to the input to (or loss from) the box or due to the production, consumption or decay of this species within the box.

盒子模型是复杂系统的简化版本，将它们简化为通量连接的盒子(或水库)。假定这些盒子是均匀混合的。因此，在一个给定的盒子内，任何化学物质的浓度都是均匀的。然而，在一个给定的盒子内的一个物种的丰度可能会随着时间的变化而变化，这是由于盒子内的输入(或损失)或这个物种在盒子内的生产、消费或衰变所致。
Simple box models, i.e. box model with a small number of boxes whose properties (e.g. their volume) do not change with time, are often useful to derive analytical formulas describing the dynamics and steady-state abundance of a species. More complex box models are usually solved using numerical techniques.

The average emissivity of the earth is readily estimated from available data. The emissivities of terrestrial surfaces are all in the range of 0.96 to 0.99 (except for some small desert areas which may be as low as 0.7). Clouds, however, which cover about half of the earth's surface, have an average emissivity of about 0.5 (which must be reduced by the fourth power of the ratio of cloud absolute temperature to average earth absolute temperature) and an average cloud temperature of about . Taking all this properly into account results in an effective earth emissivity of about 0.64 (earth average temperature ).
地球的平均比辐射率很容易从现有数据中估计出来。陆地表面的放射系数均在0.96ー0.99之间(除少数小沙漠地区可能低至0.7)。然而，覆盖地球表面大约一半的云层，其平均发射率约为0.5(必须用云的绝对温度与地球平均绝对温度之比的四次方减少) ，而云的平均温度约为0.5。适当地考虑这些因素，得到的有效地球发射率约为0.64(地球平均温度)。
This simple model readily determines the effect of changes in solar output or change of earth albedo or effective earth emissivity on average earth temperature.

Zero-dimensional models do not address the temperature distribution on the earth or the factors that move energy about the earth.
This simple model readily determines the effect of changes in solar output or change of earth albedo or effective earth emissivity on average earth temperature.

Zero-dimensional models do not address the temperature distribution on the earth or the factors that move energy about the earth.
这个简单的模型很容易确定太阳输出量的变化或地球反照率或有效地球发射率的变化对地球平均温度的影响。然而，它没有提到是什么可能导致这些事情发生改变。零维模型不能解释地球上的温度分布或者地球周围移动能量的因素。

The zero-dimensional model above, using the solar constant and given average earth temperature, determines the effective earth emissivity of long wave radiation emitted to space. This can be refined in the vertical to a one-dimensional radiative-convective model, which considers two processes of energy transport:

上述零维模型利用太阳常数和给定的地球平均温度，确定了向空间发射的长波辐射的有效地球发射率。这可以在垂直于一维辐射对流模式的方向上加以改进，该模式考虑两个能量输送过程:
* upwelling and downwelling radiative transfer through atmospheric layers that both absorb and emit infrared radiation
* upward transport of heat by convection (especially important in the lower [[troposphere]]).
* upwelling and downwelling radiative transfer through atmospheric layers that both absorb and emit infrared radiation
* upward transport of heat by convection (especially important in the lower troposphere).
* 通过大气层的上升流和下降辐射转移，这些大气层通过对流层吸收和释放红外线
* 向上传送热量(在对流层下部尤其重要)。
The radiative-convective models have advantages over the simple model: they can determine the effects of varying [[greenhouse gas]] concentrations on effective emissivity and therefore the surface temperature. But added parameters are needed to determine local emissivity and albedo and address the factors that move energy about the earth.

辐射-对流模式比简单模式有优点: 它们可以确定不同温室气体浓度对有效发射率的影响，因此也可以确定地表温度。但是需要增加参数来确定局部发射率和反照率，并解决地球周围能量移动的因素。

The zero-dimensional model may be expanded to consider the energy transported horizontally in the atmosphere. This kind of model may well be [[Zonal and meridional|zonally]] averaged. This model has the advantage of allowing a rational dependence of local albedo and emissivity on temperature – the poles can be allowed to be icy and the equator warm – but the lack of true dynamics means that horizontal transports have to be specified.<ref>{{cite web|url=http://www.shodor.org/master/environmental/general/energy/application.html|title=Energy Balance Models|work=shodor.org}}</ref>

可以扩展零维模型以考虑大气中水平输送的能量。这种模型很可能是纬向平均的。这个模型的优点是允许局部反照率和发射率与温度有合理的依赖关系——两极可以是冰的，赤道可以是暖的——但缺乏真正的动力学，这意味着必须具体说明水平输送。
== EMICs (Earth-system models of intermediate complexity) ==
{{Main|Earth systems model of intermediate complexity}}
Depending on the nature of questions asked and the pertinent time scales, there are, on the one extreme, conceptual, more inductive models, and, on the other extreme, [[general circulation model]]s operating at the highest spatial and temporal resolution currently feasible. Models of intermediate complexity bridge the gap. One example is the Climber-3 model. Its atmosphere is a 2.5-dimensional statistical-dynamical model with 7.5° × 22.5° resolution and time step of half a day; the ocean is MOM-3 ([[Modular Ocean Model]]) with a 3.75° × 3.75° grid and 24 vertical levels.<ref>{{cite web|url=http://www.pik-potsdam.de/emics/|title=emics1|work=pik-potsdam.de}}</ref>

根据所提问题的性质和相关的时间尺度，在一个极端，概念上有更多的归纳模型，而在另一个极端，大气环流模型在最高的空间和时间解析度上运行，目前是可行的。中等复杂性模型弥补了这一差距。其中一个例子是 climber-3模型。其大气为2.5维统计动力学模式，分辨率为7.5 ° × 22.5 ° ，时间步长为半天，海洋为模块化海洋模式 MOM-3，网格为3.75 ° × 3.75 ° ，垂直高度为24 ° 。
== GCMs (global climate models or general circulation models) ==
{{Main|General circulation model}}
General Circulation Models (GCMs) discretise the equations for fluid motion and energy transfer and integrate these over time. Unlike simpler models, GCMs divide the atmosphere and/or oceans into grids of discrete "cells", which represent computational units. Unlike simpler models which make mixing assumptions, processes internal to a cell—such as convection—that occur on scales too small to be resolved directly are parameterised at the cell level, while other functions govern the interface between cells.

大气环流模式(GCMs)离散了流体运动和能量传递的方程，并随着时间的推移积分这些方程。与较简单的模型不同，大气环流模型将大气和/或海洋划分为代表计算单位的离散“单元”网格。与作出混合假设的简单模型不同，单元内部的过程(例如对流)在尺度太小而无法直接解决的情况下在单元层面上被参数化，而其他功能则控制单元之间的界面。

However, they are still under development and uncertainties remain. They may be coupled to models of other processes, such as the [[carbon cycle]], so as to better model feedback effects. Such integrated multi-system models are sometimes referred to as either "earth system models" or "global climate models."

大气层大气环流模式(AGCMs)模拟大气，并把海面温度作为边界条件。大气-海洋耦合大气环流模式。结合了这两个模型。第一个将海洋和大气过程结合在一起的大气环流气候模式是在20世纪60年代末由美国国家海洋和大气管理局的地球物理流体动力学实验室气候模式发展起来的，它代表了气候模式复杂性的顶峰，并且尽可能地内化了许多过程。然而，它们仍在发展之中，不确定性仍然存在。它们可以与碳循环等其他过程的模型耦合，以便更好地模拟反馈效应。这种综合的多系统模型有时被称为“地球系统模型”或“全球气候模型”
