El Nino and La Nina
El Nino and La Nina are opposite phases of ENSO (El Nino Southern Oscillation), a coupled ocean-atmosphere oscillation in the Tropical Pacific Ocean that exerts an influence on weather throughout much of the world. Being an oscillation, it moves between these two phases every few years, triggered initially by changes in the atmospheric circulation with ocean temperature changes following. It is measured by the Southern Oscillation Index, which compares surface pressures at Tahiti and Darwin, Australia.

translation is: the boy, and it revers to Christ, since it is usually notices around Christmas. It is a climate pattern that occurs across the tropical Pacific ocean on average every five years, but over a period which varies from three to seven years, and is therefore, widely and significantly, known as "quasi-periodic".

What effect does el nino have on the eastern coast?
In 2009-2010 anyone on the eastern coast noticed a large increase in nor' easters. That's because this winter season was an El Nino. When an el nino occurs, the jet stream is shifted from its regular position in the Atlantic. It is shifted closer to the United States' east coast. This makes all of the low pressure systems follow right over it. Over time, in an El Nino year, there is an increased activity in low pressure systems up the east coast which creates more snow, rain, etc. (Nor' Easters)
Epekto ng el nino sa agrikultura?
Ang El Niño ay nagdudulot ng matinding tagtuyot sa iba't ibang bahagi ng mundo, na maaaring magdulot ng pagkasira sa pananim at kakulangan ng suplay ng tubig para sa irigasyon. Ito ay maaaring magresulta sa pagbaba ng ani at pagtaas ng presyo ng pagkain, na maaring makaapekto sa kita ng mga magsasaka at seguridad sa pagkain ng bansa.
What can be impacted by El nino?
El Niño can impact global weather patterns by causing changes in temperature, rainfall, and storms. It can lead to droughts in some regions, while causing floods in others. Additionally, El Niño can influence fisheries, agriculture, and disease outbreaks around the world.
El Niño can increase the likelihood of flooding in some regions due to changes in weather patterns such as increased rainfall. It can lead to heavy precipitation in areas that are typically dry, causing rivers to overflow and flooding. However, the impact of El Niño on flooding can vary depending on the region and other factors.

El Niño is not a fire phenomenon.
El Niño is a weather phenomena which occurs mainly in tropical waters of the Pacific Ocean and affects the region across the Pacific from New Guinea to South America. 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.
How is the Philippines affected by the El Nino?
El Nino typically brings drier and warmer conditions to the Philippines, leading to reduced rainfall, droughts, and an increased risk of wildfires. This can have negative impacts on agriculture, water resources, and food security in the country, affecting both farmers and the general population. The government often implements measures to mitigate these effects during El Nino events.
The El Niño Southern Oscillation phenomenon provides good opportunities to study?
the complex interactions between the ocean and the atmosphere. It can have significant impacts on weather patterns, ocean conditions, and ecosystems around the world, making it a valuable subject for research in climate science and meteorology. Studying El Niño and La Niña events can also improve our understanding of climate variability and help in developing more accurate climate forecasting models.
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.
El Nino refers to a warm ocean current that flows along the coast of?
El Nino refers to a climate pattern that involves the abnormal warming of ocean waters in the central and eastern tropical Pacific. This can lead to changes in global weather patterns, including increased rainfall in some regions and droughts in others.

The lack of upwelling during an El Niño period results in which of the following?
The lack of upwelling during an El Niño period results in a decrease in nutrient-rich cold, deep ocean water reaching the surface. This leads to reduced primary productivity and affects marine ecosystems that depend on these nutrients.
It began weakening during the winter, but won't really go neutral until perhaps sometime this summer, according to recent guidance.
Check out the related link - ENSO is monitored in the US by the Climate Prediction Center, which issues a very thorough report each week I believe. It can be quite technical but also provides a lot of graphics and explanations.
the cause is the heat forming in the center of the ocean . the effect is simply la nina
La Nina can only form after an El Niño. During an El Niño, types of waves, not beach waves, but massive movements of energy through water, are formed. They are Kelvin waves and Rossby waves. As Kelvin waves are formed, they push cold water down, which initially causes the ocean to warm. At the same time, another series of waves, Rossby waves, also form under water. They roll towards Asia and Australia. When the waves hit the coast, they reverse and head back towards South America. As the Rossby waves return, they leave cold water closer to the surface. If they bring back just enough cold water, the ocean temperatures return to normal, but sometimes they bring back to much, causing a La Niña after an El Niño.
What are some of the dangers of an El Nino?
El Nino effects the weather most of all; last year, areas in the United States unaccustomed to snow got a foot or more due to the change in El Nino's current; this caused millions of dollars in damage.
How might el nino affect societies of the dry pacific coast over time?
El Niño can bring heavy rainfall and flooding to typically dry regions along the Pacific coast, leading to landslides, crop damage, and infrastructure destruction. This can disrupt economies, displace communities, and strain resources, impacting livelihoods and increasing vulnerability to future extreme events. Over time, repeated El Niño events can exacerbate these challenges, leading to long-term social, economic, and environmental consequences for societies on the dry Pacific coast.
El nino causes a vast sheet of water to move across the pacific ocean toward the coast of?
El Niño is a climate phenomenon characterized by warmer-than-average sea surface temperatures in the equatorial Pacific Ocean. This warming can lead to changes in weather patterns worldwide, including increased rainfall and flooding in some regions and droughts in others. The effects of El Niño can vary depending on the strength and duration of the event.
When did la Nina and el nino occur at same time?
La Niña and El Niño occur at different times and are opposite phases of the El Niño-Southern Oscillation (ENSO) cycle. It is rare for them to occur at the same time, but it can happen during a transition period when one phase is weakening and the other is starting to strengthen. This transitional phase is known as ENSO neutral.
What is El Nino how is it caused and what are its effects?
[American Spanish, from Spanish, the Christ child (from its onset being around Christmastide) : el, the (from Latin ille) + niño, child (from Old Spanish ninno, from Vulgar Latin *nīnnus).]
An El Nino event results from weakened trade winds in the western Pacific Ocean near Indonesia, allowing piled-up warm water to flow toward South America.
The deeper, warmer water in the east limits the amount of nutrient-rich deep water normally surfaced by the upwelling process. Since fish can no longer access this rich food source, many of them die off. This is why these conditions are called "El Nino", or "the Christ Child", which is what Peruvian fisherman call the particularly bad fishing period around December. More importantly, the different water temperatures tend to change the weather of the region.
What happens to the ocean also affects the atmosphere. Tropical thunderstorms are fueled by hot, humid air over the oceans. The hotter the air, the stronger and bigger the thunderstorms. As the Pacific's warmest water spreads eastward, the biggest thunderstorms move with it. If you look on a map, you will see that suddenly islands like Tahiti, normally tropical paradises, experience massive storms.
Currently, it is not well understood what initiates these changes, and it is likely that it is a large combination of things. The current thinking is that it has to do with oscillations such as the Madden-Julian Oscillation in the tropical Pacific, Atmospheric Angular Momentum, and frictional and mountain torque.
What does a weak El nino cause?
A weak El Niño can lead to mild changes in global weather patterns, such as slightly warmer ocean temperatures in the eastern equatorial Pacific, increased rainfall in certain regions, and reduced hurricane activity in the Atlantic Ocean. The impacts are usually less severe compared to moderate or strong El Niño events.
Some past El Niño years include 2015-2016, 2009-2010, 2002-2003, and 1997-1998. These events are characterized by warming of sea surface temperatures in the central and eastern tropical Pacific Ocean, leading to global climate impacts.
