- Use the techniques learned above to investigate SST variations in other years.
- Expand on this investigation by downloading rainfall data from PMEL and compare rainfall patterns associated with normal, El Nino, and La Nina years. The rain follows the warm water. Therefore, during an El Nino year, it is dryer than normal in the Western Pacific, and wetter in the Eastern Pacific.
- Investigate the relationship between SST and Precipitation patterns in the countries bordering the Pacific Ocean.
- Investigate El Nino Impacts. See graphic in the Case Study for ideas.
