Climate model - Wikipedia
Climate models are systems of differential equations based on the basic laws of physics, 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.
Climate Models - MIT Climate Portal
Climate models are computer programs that simulate weather patterns over time. By running these simulations, climate models can estimate the Earth’s average weather patterns—the climate —under different conditions.

2014年11月21日 · Climate models, also known as general circulation models or GCMs, use mathematical equations to characterize how energy and matter interact in different parts of the ocean, atmosphere, land.
Climate Model Bias 1: What is a Model? - Andy May Petrophysicist
2024年2月28日 · In this series of seven posts on climate model bias we are only concerned with two of them. The first are mathematical models that utilize well established physical, and chemical processes and principles to model some part of our reality, …
Climate Models - NOAA Climate.gov
This video explains how scientists construct computer-generated climate models to forecast weather, understand climate, and project climate change. It discusses how different types of climate models can be used and how scientists use computers to build these models.
What is a climate model? - NCAS
A climate model is a computer simulation of the Earth’s climate system, including the atmosphere, ocean, land and ice. They can be used to recreate the past climate or predict the future climate.
What Are Climate Models and How Accurate Are They?
2018年5月18日 · Essentially, climate models are an extension of weather forecasting. But whereas weather models make predictions over specific areas and short timespans, climate models are broader and analyze long timespans. They predict how average conditions will change in a region over the coming decades.
Climate Modeling - Geophysical Fluid Dynamics Laboratory
A global climate model (GCM) is a complex mathematical representation of the major climate system components (atmosphere, land surface, ocean, and sea ice), and their interactions. Earth’s energy balance between the four components is the key to long-term climate prediction.
NASA GISS: Global Climate Modeling - Goddard Institute for …
2024年7月12日 · Ongoing field and laboratory programs in palynology, paleoclimate reconstruction, atmospheric clouds and convection, dust processes, and other geophysical sciences provide fundamental climate data for evaluating model predictions.
Basics of Global Climate Models | USDA Climate Hubs
Global climate models are computer programs that consist of several hundred thousand lines of code. They calculate the interactions between the ocean, atmosphere and land using factors such as water vapor, carbon dioxide, heat, and the Earth’s rotation as inputs.
