What is a change in the water temperature of the eastern pacific ocean that produces cooler than usual surface water temperatures?
California Current
What else can I help you with?
Which of the following statements about sea surface temperature is evidence of an El Nino year?
greater than normal in the Eastern Pacific
A change in the water temperature of the Pacific Ocean that produces a warm current called?
A change in the water temperature of the Pacific Ocean that produces a warm current is known as El Niño. This phenomenon occurs when warm water accumulates in the central and eastern Pacific, affecting global weather patterns. El Niño can lead to increased rainfall in some regions and droughts in others, significantly impacting agriculture and ecosystems.
How is la Nina triggered?
colder than average surface temperatures in the eastern pacific
A change in the water temperature of the eastern pacific ocean that produces cooler than usual surface water temperatures?
This phenomenon is known as La Niña. It can impact global weather patterns by influencing wind patterns and ocean currents, leading to cooler and wetter conditions in some regions and drier conditions in others. La Niña events are part of the broader El Niño-Southern Oscillation (ENSO) cycle.
How are El Nino sea surface temperatures and weather conditions different from normal conditions?
"Trade winds diminish in the Central and Western Pacific. The thermocline is depressed in the east and elevated in the west. Sea surface temperatures stay high when usually, the temperature drops in the Eastern Pacific. (The thermocline is a drop in sea temperature.)" NOAA Research; El Nino Activity Key

How does rainfall in the eastern pacific compare to the rainfall in the western pacific?
Rainfall in the eastern Pacific is typically lower than in the western Pacific. The eastern Pacific tends to have a drier climate due to the presence of the cold California Current that limits moisture transport. In contrast, the western Pacific, near the equator, receives higher rainfall amounts due to the warmer ocean temperatures and greater atmospheric convection.
What changes occur in the pacific ocean during El Nino?
During El Niño events, the Pacific Ocean experiences warmer than average sea surface temperatures in the central and eastern tropical Pacific. This disrupts normal weather patterns, leading to increased rainfall in the eastern Pacific and drought conditions in the western Pacific. The changes in ocean temperatures also affect global atmospheric circulation patterns, influencing weather patterns around the world.
El Nino is a condition that brings increased precipitation to the eastern Pacific Ocean basin when?
El Niño occurs when ocean temperatures in the central and eastern Pacific Ocean become warmer than usual, leading to changes in atmospheric circulation patterns. This can result in increased precipitation in the eastern Pacific Ocean basin, including countries like Peru and parts of North America.
What describes the pressure changes happening in the pacific during an El Ni and ntildeo year?
During an El Niño year, the pressure in the central and eastern Pacific Ocean decreases, leading to weaker trade winds and warmer sea surface temperatures. This shift in atmospheric pressure results in increased precipitation in the eastern Pacific and drier conditions in the western Pacific. Conversely, during a La Niña year, the pressure patterns reverse, with increased pressure in the eastern Pacific, stronger trade winds, and cooler sea surface temperatures, often causing wetter conditions in the western Pacific. These fluctuations significantly impact global weather patterns.
When is the eastern Pacific warmer then normal?
The eastern Pacific Ocean is typically warmer than normal during El Niño events, which occur every few years when there is an abnormal warming of sea surface temperatures. This can lead to widespread impacts on weather patterns around the world.
