In this activity learners investigate the link between ocean temperatures and hurricane intensity, analyze instrumental and historical data, and explore possible future changes.

In this activity, students examine global climate model output and consider the potential impact of global warming on tropical cyclone initiation and evolution. As a follow-up, students read two short articles on the connection between hurricanes and global warming and discuss these articles in context of what they have learned from model output.

This activity allows students to make El Nino in a container, but it might work better as a teacher demonstration. The introduction and information provided describe El Nino, its processes and its effects on weather elsewhere in the world.
