How does the weather changes in both the eastern and western pacific during el nino year?
El Niño is a weather phenomena which tends to occur in tropical waters of the Pacific Ocean. It affects the region across the Pacific from New Guinea to South America, known as the Equatorial Pacific. During an El Niño season, which occurs on average every 2-7 years, a shift in ocean currents and winds brings warm water in a westerly direction, displacing the usual cold water that comes up from the ocean depths. As well as affecting marine life, the El Niño has an effect on weather patterns.
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 in the west, while the unusually warm eastern waters bring heavy rains and floods to the Pacific coast of South America, which is usually much drier.
It's all a matter of interactions between the oceans and the atmosphere. Changes in sea surface temperatures causes a shift in air pressure which, in turn, can result in climatic anomalies, such as severe droughts, flooding and even cyclones. One of the effects is that the normal circulation patterns over the Pacific are disrupted, and moisture-bearing trade winds weaken, whilst drier westerlies increase.

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.
Are hurricanes always called hurricanes?
No they are not always called hurricanes. Win the western Pacific they are called typhoons and in the southern Pacific they are called cyclones. The generic term is tropical cyclone.
What condition trigger a la nino episode?
A La Niña episode is triggered by a combination of cooler-than-average sea surface temperatures in the central and eastern Pacific Ocean and changes in wind patterns. Specifically, strong trade winds push warm water toward the western Pacific, allowing colder water to rise from the depths in the east. This phenomenon impacts global weather patterns, often resulting in increased rainfall in the western Pacific and drier conditions in the eastern Pacific. The interaction between ocean temperatures and atmospheric conditions is crucial for the development of La Niña.
What are Canada's time zones?
eastern, western, central, pacific, Atlantic and Newfoundland
Is ny eastern or pacific time?
NY is on Eastern time. Pacific time is in the Western part of the US (on the left side of a map).
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.
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.
Which ocean is located in the northern eastern and western hemi?
Pacific
What is the nearest oceans?
It depends on where you live. Western USA: Pacific Ocean Eastern USA: Atlantic Ocean
What strait of water divides the eastern and western hemisphere?
That would have to be the Atlantic and Pacific oceans.
In this cartoon how are the eastern and western sections of the US divided P?
The eastern and western sections of the US are divided based on the time zones. The eastern portion follows Eastern Standard Time (EST) or Eastern Daylight Time (EDT), while the western portion follows Pacific Standard Time (PST) or Pacific Daylight Time (PDT).
Are hurricanes always called hurricanes?
No they are not always called hurricanes. Win the western Pacific they are called typhoons and in the southern Pacific they are called cyclones. The generic term is tropical cyclone.
