UWHS ATMS 211: ENSO (El Nino/Southern Oscillation) Investigation

created by Nancy Flowers


This module provides a hands-on learning experience where students will analyze sea surface temperature data collected over half a century. They will then use this data to determine if the year was an El Niņo, La Niņa, or normal year. The objective of this module is to have students learn about climate variability, data analysis, and be able to understand the content well enough to create predictions.
