#Ocean phenomena how to
The resources in this collection can be used to help learn about the basics of ENSO, the inter-relationship of Earth systems, the consequences of these interactions, and how to use and analyze data. Fishing in this region is best during La Niña years when cold upwelling ocean water brings rich nutrients offsite link from the deep ocean, resulting in an increase in the number of fish caught.ĮNSO provides teachers with the opportunity to have students discover ways that the oceanic and atmospheric systems interact and how those interactions can impact ecosystems and human society. Known as the green flash, this is an interesting illusion created when the rays of the sun are separated out as it fades or comes into view. at sunrise or sunset, there may be a few seconds where the sun flashes green. Referring to the birth of Christ, they named the warm ocean waters, El Niño, which means “the boy” in Spanish. When looking out over the ocean, a cool phenomena can occur with the sun. This warm water would arrive around Christmastime. Fish catches would drop drastically, negatively affecting the food supply and livelihood of the communities of coastal Peru. The origin of the name “El Niño” dates to the 1800’s, when fishermen on the Pacific coast of South America would notice that a warm ocean current would appear every few years. Agriculture is of course very dependent on climate and weather, as a result ENSO’s influence on rainfall and temperature have important consequences for food production and availability.
This can impact individuals who make a living fishing and consumers who depend on certain fish for food. Changes in ocean temperatures and currents that happen during El Niño impact marine life. Conversely, La Niña events tend to be related to an increase in the number of Atlantic hurricanes.įood production is impacted by ENSO. Even though El Niño occurs in the Pacific Ocean, it often reduces the number of hurricanes that form in the Atlantic Ocean. La Niña, however, usually causes drier weather in the South, but the Northwest tends to be colder and wetter than average. For example, in the Southern United States, during the fall through spring, El Niño usually causes increased rainfall and sometimes destructive flooding.
