What is a occurrence in the eastern Pacific Ocean in which the surface-water temperature becomes unusually warm or cool?
It is called an El Niño event, and has weather implications for much of North America.
What else can I help you with?
What kind of weather conditions would you expect to find in Australia during La Niña?
The water in the western Pacific is typically warmer than in the eastern Pacific because trade winds blow the warm waters of the eastern Pacific westward and keep it there. Also, upwelling in the eastern Pacific keeps the water cooler.The warmer water creates more clouds and rain, keeping Indonesia and other areas of the western Pacific wetter than Peru and other coastal regions of South America.During El Niño, the pressure gradient (rate of pressure change between areas of high and low pressure) weakens. In the western tropical Pacific, there is unusually high air pressure, while there is unusually low air pressure in the eastern tropical Pacific. This Southern Oscillation causes the trade winds to weaken, and even blow backwards. This pattern reversal leads to unusually wet weather in parts of South America, and unusually dry weather in the western Pacific.El Nino usually occurs every 3 to 7 years, and lasts for about 18 months.La Niña is the opposite of El Niño. These two weather patterns oscillate every few years.During La Niña, there is unusually low air pressure over the western tropical Pacific, and unusually high air pressure in the eastern tropical Pacific. The easterly blowing trade winds strengthen, blowing more warm water away from the equatorial Pacific. As a result, Australia and Indonesia become wetter than normal, and parts of South America become drier than normal.
What happens to the temperature of the ocean during a El Nino year?
During an El Niño year, the temperature of the ocean in the equatorial Pacific tends to be warmer than usual. This warming of the ocean can lead to disruptions in weather patterns globally, affecting precipitation, wind patterns, and temperatures in various regions.
Which of the following statements about sea surface temperature is evidence of an El Nino year?
greater than normal in the Eastern Pacific
Where does El Nino usually hit?
El Niño is a weather phenomena, the effes of which extend across a wide range. It tends to occur mainly in the tropical waters of the Pacific Ocean. It affects the region across the Pacific from New Guinea and Australia to South America. Under normal conditions, in the tropics warm oceans tend to be accompanied by heavy rains, resulting in heavy rains in the warm west Pacific while the cooler east Pacific receives far less rainfall. This is reversed during an El Niño, when the ocean temperature gradient from one side of the Pacific to the other weakens. Warmer than usual ocean temperatures cause droughts across Australia, while the unusually warm eastern waters bring heavy rains and floods to the Pacific coast of South America, which is usually much drier.
La Nina is characterized by unusually ocean temperatures?
La Niña is a climate pattern that is characterized by cooler-than-normal sea surface temperatures in the central and eastern Pacific Ocean. This can lead to specific weather patterns around the world, such as increased rainfall in some regions and drought in others. La Niña events typically occur every few years and can impact global weather for several months to a year.
Why does the pacific ocean have such a large impact on global weather?
The sea surface temperature in the equatorial pacific ocean. El Niño is characterized by unusually warm temperatures and la Nina by unusually gets cool temperatures in the equatorial pacific. El Niño can be very destructive and can cause floods, It is very dangerous to cities.
What causes unusually cool waters and low rainfall in the eastern pacific and heavy rains in the western pacific?
El Nino
What causes unusually cool waters and low rainfall in the eastern Pacific and heavy rains the Western pacific?
El Nino
What is caused by unusually warm temperatures in the Pacific Ocean near the equator?
El Niño
What is caused by unusually warm ocean temperatures in the Pacific Ocean near the equator?
El Niño
Does the Pacific Ocean affect the weather on Honolulu?
yes stupid it is a natural occurrence
Is El Nino a cold body of water that gathers in the arctic?
No, El Nino is an unusually warm change in temperatures of the Tropical Pacific Ocean.
Is the ring of fire a composite volcano?
No. The ring of fire is not a volcano. It is the area around the edge of the Pacific Ocean that experiences unusually high volcanic activity.
Average temperature in the pacific ocean?
65
When the pacific plate is sliding under the oceanic crust of japan forming an island area what type of occurrence would this be?
This is called subduction.
Which ocean has the warmest temperature Atlantic or pacific?
Atlantic
