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.

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.
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.
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.

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.
How Earth Climate Models Help Scientists Picture Life on ... - NASA
2020年1月24日 · Among many other factors, climate models consider how clouds and oceans circulate and interact and how radiation from a sun interacts with a planet’s atmosphere and surface. When Del Genio’s team ran ROCKE-3D on Discover they saw that Proxima b’s hypothetical clouds acted like a massive sun umbrella by deflecting radiation. This could ...
Climate models: applications to understand past climates and climate ...
2015年11月30日 · Combining climate models with data-based climate reconstructions provides a way of discovering and understanding the mechanisms of climate change and explicitly tests the ability of the models to capture known changes in climate.
Earth & Environmental Systems Modeling
2024年11月25日 · The Regional & Global Model Analysis (RGMA) program area advances the predictive understanding of Earth’s climate by focusing on a scientific analysis of the dominant sets of governing processes that describe climate variability and change at scales ranging from global to regional, and subseasonal to centennial.
