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.

How does la Nina and el nino affect kansas weather?
La Niña and El Niño are climate patterns that influence weather across the globe, including Kansas. During La Niña, Kansas typically experiences cooler and wetter conditions, especially in winter, while El Niño often brings warmer and drier conditions. These patterns can affect precipitation levels, temperature fluctuations, and the overall severity of weather events, such as storms and droughts, impacting agriculture and water resources in the region.
How does el nino cause flooding?
El Niño can cause heavy rainfall in certain regions due to changes in ocean temperatures and atmospheric circulation patterns. This increased rainfall can lead to flooding as the excess water overwhelms rivers, lakes, and drainage systems. The combination of warmer sea surface temperatures and altered wind patterns can disrupt normal weather patterns, leading to more severe and sustained rainfall events.
What does upwelling have to do with el nino?
El Nino reduces upwelling. Normal sea surface temperatures in Pacific tend to be warmer in the west because of upwelling, where warm water flows west because of trade winds and colder water rises up to replace the warm water in the Eastern Pacific. During El Nino, the trade winds get all screwed up and warm water is spread out more evenly in the Pacific. So there is less upwelling and the Eastern Pacific sees warmer sea water.
El nino does it bring flood to the pacific coast?
El Niño is associated with heavy rainfall and can lead to flooding on the Pacific coast. This is due to changes in sea surface temperatures that disrupt normal weather patterns, causing increased precipitation in some regions. However, not every El Niño event results in flooding, as the impact can vary depending on local conditions.
Historical, both thermometers and barometers have used mercury.
How does an El Nino affect Kentucky?
Winters tend to be considerably drier, especially in the western and southern parts of the state. There is generally not inclination either way for temperature.
What human activities affect the el nino phenomenon?
Human activities contribute to the intensification of El Niño through activities such as deforestation, which can affect global climate patterns. Climate change caused by greenhouse gas emissions also impacts the strength and frequency of El Niño events. Additionally, activities like overfishing and pollution can disrupt ocean ecosystems, potentially influencing the development of El Niño events.
Is the US currently in la Nina or el nino?
El Niño and La Niña (collectively called El Niño Southern Oscillation or ENSO) don't just affect the US. They affect the whole world. As of October 2013, the current condition is ENSO neutral, meaning we have neither El Niño nor La Niña, but are somewhere in between.
How does El Nino affect industries in Mozambique?
El Nino affects industries in mozambique because of the weather changes.
What do you call a scientist who studies el nino?
They would probably either be an Atmospheric Scientist or an Oceanographer if they were studying the phenomenon itself, depending on which aspect they're looking at.
When does the next El Nino phenomena occur?
El Nino is a weather phenomenon which causes extreme and unpredictable weather conditions every three to six years and can last up to twelve months. It is close to impossible to predict when the next one will occur until scientists see the warning signs occurring.
What can the unexpected warn waters during an El nino cause?
During El Niño, unexpected warm waters can cause disruptions in weather patterns worldwide, such as increased rainfall in some regions leading to flooding and droughts in others. It can also impact marine life and ecosystems by altering distribution of fish populations and leading to coral bleaching events. These disruptions can have significant economic and social consequences.
What do citizen of a country often share?
Citizens of a country often share a common identity, culture, language, history, and values that unite them as part of a collective community. They also typically share equal rights and responsibilities as outlined by the laws and regulations of their country.
Why was there fewer fish during El Nino?
There are fewer fish during El Nino because El Nino causes dramatic temperature fluctuations. This combined with rapidly rising or decreasing water levels lead fish to find a more stable environment in which to live.
Explain the relationship between El Nino and upwelling?
El nino needs to be answered for real people anyway El nino mixes with upwelling and creates don't know but it can kill you
Is it true that el nino and al Nina influence weather only along the west coast of the US?
No, El Niño and La Niña events can influence weather patterns globally, not just along the west coast of the US. These phenomena are linked to changes in sea surface temperatures in the Pacific Ocean, which can impact weather patterns, including rainfall, temperature, and storm activity, in various regions around the world.
Name three disasters caused by El Nino?
- Severe droughts in places like Australia, leading to water shortages and agricultural losses.
- Increased rainfall and flooding in South America, such as Peru, causing infrastructure damage and loss of life.
- Intensified hurricanes in the Pacific Ocean, affecting countries like the Philippines and impacting coastal communities.
How many major windstreams are there on Earth?
There are two major wind streams on earth. The solar wind stream and the gulf wind stream. There are some minor wind streams such as El nino, and La nina. These wind streams have an effect on the weather and climate.
