Simulating the Great Lakesโ€”past, present, and future.

GLFCFS Wave Height example

If you are thinking about going for a swim, but Lake Superior is cold when you dip your toe in, itโ€™s usually safe to say that all the water nearby is also cold.

In the same way, scientific models take on-the-ground observations from platforms like buoys and weather towers and create simulations of lake conditions right now (nowcast), show what happened in the past (hindcast) and even predict the future (forecast).

Models give observers lake-wide snapshots to help them boat safely, understand shoreline erosion, know if an area is at high risk from a chemical spill, and more.

Created from complex equations and deep knowledge of the water system, models can be built to simulate:

  • Water currents and temperature
  • Wave height and direction
  • Chemical spills
  • And much more
