During El Niño, trade winds weaken, allowing warm water from the western Pacific to flow eastward toward the coast of South America. This shift disrupts the normal upwelling of cold, nutrient-rich waters off the coast, leading to a rise in surface water temperatures. The warmer temperatures can significantly impact marine ecosystems, weather patterns, and fisheries in the region.

Why do surface-water temperatures on the west coast of south America rise during El Nino?

During El Niño events, the trade winds weaken, leading to a reduction in upwelling along the west coast of South America. This upwelling typically brings cold, nutrient-rich water from the deep ocean to the surface, but when it diminishes, warmer surface waters dominate. As a result, the sea surface temperatures increase, disrupting local marine ecosystems and weather patterns. This phenomenon can lead to various climatic effects, including altered precipitation patterns and increased storm activity in the region.

Which statement describes sea surface temperatures along the South American coast and Pacific trade winds during El Nino?

During El Niño, sea surface temperatures along the South American coast are warmer than usual, and the Pacific trade winds weaken or even reverse their typical direction. This deviation from normal conditions is a key indicator of an El Niño event.


During an El Nino winds drag ocean water causing what?

During an El Nino event, the weakened trade winds allow warm surface waters in the western Pacific Ocean to move eastward towards South America. This can cause an increase in sea surface temperatures, changes in weather patterns, and disruptions in marine ecosystems.


Which two 23.5 degree latitude locations are influenced by cool surface ocean currents?

The two locations at 23.5 degrees latitude that are influenced by cool surface ocean currents are the western coast of South America, particularly near Peru, and the eastern coast of Australia. In Peru, the cold Humboldt Current brings cooler temperatures, while the East Australian Current off the coast of Australia affects the climate and marine ecosystem in that region. These cool currents contribute to lower sea surface temperatures and influence local weather patterns.

What is an effect of Nina?

Ocean temperatures off the west coast of South America decrease.


How is weather on the western coast of Africa effect the weather on the eastern coast of north America?

Weather patterns along the western coast of Africa can influence the formation of tropical storms and hurricanes, which can then track across the Atlantic Ocean and impact the weather on the eastern coast of North America. Warmer sea surface temperatures off the coast of Africa can provide more energy for these storms to develop and strengthen before reaching North America.

What current keeps our west coast warm during winter?

The California Current is a significant ocean current that travels southward along the west coast of North America, helping to moderate temperatures in the region. During winter, it brings relatively warmer waters from the north, contributing to milder weather along the coast. This current, combined with coastal geography, helps prevent extreme cold temperatures, making the west coast more temperate compared to other regions at similar latitudes.


What is the pattern of warmer than normal pacific ocean surface temperatures in Georgia?

Georgia is on the east coast of the USA. The Pacific is on the west coast. There is no answer for this question. There would be no affect.
