Activity: Storm Behavior
Summary: Students use maps, charts and tables to investigate the impacts of storm surges and seiches.
- Downloads – Part 2
As a whole class:
- Define storm surges and seiches and discuss storm behavior in the Great Lakes region.
- Students use Figures (Part 1) to answer questions on their data sheets.
In small groups, read the downloaded storm narrative.
- Use Figures (Part 2) to complete data sheet. (Use links to NOAA chart and USGS maps to view in greater detail.)

In most places, climate change is predicted to cause water levels to rise. Currently in the Great Lakes, climate change is being blamed for drops in lake levels. It is not known whether lake levels will rise or fall in relation to climate change. However, climate change is anticipated to influence runoff, precipitation and evaporation.
- Investigate current water level, wind speed and atmospheric pressure at stations in the Great Lakes region at NOAA National Ocean Service (NOS).
- See: Great Lakes online/Water level
- Investigate extreme water levels at stations in the Great Lakes region at NOAA Center for Operational Oceanographic Products and Services (CO-OPS).
