Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the model architectures?Includes Atmospheric GCMs (AGCMs), Oceanic GCMs (OGCMs), and Coupled Atmosphere-Ocean GCMs (AOGCMs)
2. What is a General Circulation Model (GCM)?A GCM is a big computer program that pretends to be Earth’s atmosphere or ocean. It uses math equations that describe how air and water move to predict temperature, wind, and rain. It helps scientists see how the planet works.
3. How do GCMs help us predict the weather and climate?By running the program with different future scenarios, GCMs show how temperatures, storms, and sea levels might change. They let scientists test ideas and plan for the future.

Navier-Stokes Equations: Fundamental partial differential equations describing the motion of viscous fluid substances, crucial for GCMs.
Parameterization: Approximating complex physical processes that occur at scales smaller than the model grid.
Earth System Model (ESM): An advanced GCM that integrates atmospheric, oceanic, land, ice, and biogeochemical processes.
