The surface ocean currents have actually a strong effect on Earth"s climate. Areas near the equator receive more direct solar radiation than locations near the poles. However, these areas do not constantly acquire warmer and also warmer, because the ocean currents and also winds transport the warm from the lower latitudes near the equator to greater latitudes near the poles.
You are watching: Why is it warmer near the equator than near the pole
Large quantities of heat deserve to be absorbed and save on computer in the surface layers that the ocean. This warm is transported by ocean currents. In this way, the s currents assist regulate Earth"s climate by facilitating the carry of warmth from heat tropical locations to colder areas near the poles.
The an international wind patterns cause the surface currents to form in the uppers layer of the ocean. Whereby these winds blow in the very same direction for lengthy periods the time, huge currents develop and also transport vast amounts the water over lengthy distankeolistravelservices.com.
As these currents flow along the edges of continents, they influence the temperature that the coastal regions. Along the east coast of the U.S., the Gulf stream carries heat water from the equatorial an ar to the phibìc Atlantic Ocean, maintaining the south-east coast fairly warm. Along the west coast of the U.S., the California present carries cold water indigenous the polar region southward, maintaining the west coast reasonably cooler than the eastern coast.

El Niño-Southern Oscillation (ENSO)
The El Niño-Southern Oscillation (ENSO) is a bike of changing wind and also ocean present patterns in the Pacific Ocean. Normally, warmer water is transported westward in the Pacific s by the southeast trade winds till it accumulates near Indonesia. This heat water in the western Pacific Ocean reasons low wait pressure and high rainfall. (Warmer water reasons the air above the ocean"s surface to warm and also rise, leaving an area of reduced pressure. Much more rainfall is associated with reduced air pressure.)
Meanwhile, the east Pacific Ocean has high wait pressure and also less rainfall. Every 3 come 10 years, the southeast trade winds weaken, allowing the heat water to circulation further eastward toward south America. Historically, this warmer present of water typically reached the western coastline of southern America close to Christmas and also became know to the Peruvian anglers as El Niño (for the Christ child). El Niño, also known as the warm-water phase of the ENSO, reasons the water temperature off of south America to be warmer and prevents the upwelling of nutrient-rich cold water. This occasion can have terrible effects on naval life, including coral reefs, and also fisheries. An El Niño warm-water phase likewise changes an international weather patterns. Southern America experienkeolistravelservices.com wetter than mean weather while north America experienkeolistravelservices.com mild, but stormier winter weather. Throughout an El Niño phase, there room fewer and less extreme hurricanes in the Atlantic Ocean. Sometimes, after an El Niño subsides, a colder-than-normal water phase, known as La Niña, results.
Red, orange, and also white indicate areas where the sea surface elevation anomalies are higher than normal. Cyan, blue, and violet indicate sea surface elevation anomalies less than normal. Sea surface is higher when the water is warmer as result of thermal expansion. Heat water is less dense and takes up much more volume, for this reason the sea surface elevation is higher.
