This presentation was produced by the Lawrence Livermore National Laboratory and depicts the Global/Regional Interdependencies in Climate Models and Observations.
The presentation consists of:
• Introduction to Global Climate Models (GCMs)
• Validation of GCM climate simulations
• Global à Regional climate connections
• Regional à Global climate connections

TEACHING NOTES / CONTEXT FOR USE
This PowerPoint presentation can be used to demonstrate how these complex computer programs(collections of numerical algorithms) are:
- Our chief tools for simulating both the historically observed climate and potential future climate change…
- Are based on sets of coupled, nonlinear, time-dependent differential equations that represent physical forcings (e.g. solar heating S, infrared cooling I, turbulent heat transfers H), the dynamics of atmosphere/oceans (e.g. winds and currents), and their interactions with land and sea ice…
- The governing differential equations are approximated as finite differences that are solved (on computers) in grid boxes that map the globe
At the discretion of the educator.
