About this app
El Niño and the Southern Oscillation is an interactive Earth science learning app that models how trade-wind strength affects ocean temperature and upwelling in the Pacific. Explore normal conditions, weaken or strengthen the winds to create El Niño or La Niña patterns, and observe how rain clouds, drought, and heavy rainfall shift between the western and eastern Pacific.
Use cases
- High school students studying Earth science and climate
- Teachers demonstrating ENSO processes in class
- Learners exploring ocean circulation and upwelling
- Science experiment activities comparing El Niño, La Niña, and normal conditions
Features
- Three interactive sections covering normal oceans, weaker winds, and shifting rain clouds
- Adjustable trade-wind strength with weak, normal, and strong settings
- Visual model of warm surface water, cold-water upwelling, and eastern Pacific temperature anomalies
- Mission-based activities for creating El Niño, La Niña, and average conditions
- Comparison of rainfall, drought, and flood patterns across ocean states
