El Niño is a climate pattern characterized by the unusual warming of surface waters in the eastern tropical Pacific Ocean. It is the warm phase of the El Niño Southern Oscillation (ENSO) cycle, while the cool phase is called La Niña. El Niño can have significant economic impacts through effects on agriculture, fisheries, energy, tourism and trade. Countries try to mitigate these impacts through early warning systems, climate modeling, adapting water and agricultural practices, and disaster preparedness.

El Niño and La Niña are oscillations in atmospheric and oceanic temperatures known as ENSO that affect weather patterns. El Niño occurs when sea surface temperatures in the Pacific are warmer than usual, weakening trade winds and affecting rainfall. La Niña is the opposite phase, with cooler sea surface temperatures off the coast of South America. These fluctuations impact weather globally, causing storms, droughts, and altering currents. While ENSO brings changes that are unpredictable and can be destructive through hurricanes or mudslides, it also redistributes water and keeps circulation active in oceans and atmosphere.
El nino & La Nina
El Niño and La Niña are fluctuations in ocean temperatures and atmospheric conditions in the Pacific Ocean that impact weather worldwide. El Niño occurs when sea surface temperatures are warmer than average off the coast of South America, while La Niña is the opposite phase with cooler than average temperatures. These phenomena affect rainfall patterns and storm activity globally, which can sometimes result in hurricanes, floods or drought. While generally unpredictable in their timing and intensity, El Niño and La Niña are part of a natural cycle called ENSO that influences climate on Earth.

El Niño & La Niña
El Niño and La Niña are opposite phases of the El Niño-Southern Oscillation (ENSO) cycle. El Niño involves unusually warm waters in the eastern Pacific, while La Niña features unusually cold waters. These phenomena impact weather worldwide by affecting wind and rain patterns. During El Niño, the western U.S. tends to be wetter and cooler, while Australia and Indonesia experience drought. La Niña has opposite effects, with wetter conditions in Australia and Indonesia and drier weather in the western U.S. Scientists monitor these cycles using ocean buoys and satellites to improve predictions of their development and impacts.

El Niño is a naturally occurring event that causes temporary changes to the global climate. It originally referred to warmer than normal sea surface temperatures off the coast of South America in the Pacific Ocean. Now it refers more broadly to a complex set of changes in Pacific Ocean temperatures and weather worldwide. Fishermen first noticed unusually warm water appearing off South America around Christmas, so they called it El Niño, which means "the boy child" or "Christ child" in Spanish. Scientists now use the term ENSO (El Niño southern oscillation) to describe the seesaw shift in air pressure between the eastern and western Pacific Ocean that causes the temperature changes associated with El Niño.
Southern osscilation
The Southern Oscillation is a periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean that affects global climate. It involves alternating phases known as El Niño and La Niña. During El Niño, trade winds weaken and warmer waters shift eastward, while during La Niña trade winds strengthen and cooler waters shift westward. This cycle, known as the El Niño-Southern Oscillation (ENSO), typically occurs every 2-7 years and influences weather patterns and ocean temperatures around the world.
El_Nino_and_La_Nina_PPt.pptx
This document discusses El Niño and La Niña weather phenomena in the Pacific Ocean and their impact on weather patterns. El Niño occurs when warm water builds up off the coast of South America due to weak trade winds, while La Niña happens when strong trade winds cause colder than normal water temperatures. These shifts in ocean temperature can significantly affect weather worldwide, such as causing floods in some areas and droughts in others. The document provides definitions of El Niño and La Niña, their causes, typical duration and examples of damage caused by each.
Enso cycle La Nina & El Nino
El Niño and La Niña are opposite phases of the El Niño-Southern Oscillation (ENSO) cycle, which involves irregular changes in ocean temperatures and weather patterns in the equatorial Pacific. El Niño brings unusually warm water to Peru and Ecuador, weakening trade winds and affecting global weather. It occurs every 2-7 years and can cause flooding in some areas and drought in others. The thermocline and convective loops influence the cycle. Scientists monitor buoys and use models to predict when El Niño and La Niña events will occur.

El Niño is a natural phenomenon where the eastern Pacific Ocean experiences extended warming, weakening trade winds and affecting weather patterns globally. It occurs irregularly every 2-7 years and lasts 9-24 months. During El Niño, the Philippines typically experiences above average rainfall in some areas and drought in others. Its opposite, La Niña, is characterized by strengthened trade winds and cooler ocean temperatures in the eastern Pacific, bringing above normal rainfall to the Philippines. While El Niño/La Niña have large impacts, their causes are still being researched and they remain difficult to predict.
Climate change report
El Niño and La Niña are naturally occurring climate patterns in the Pacific Ocean that impact global weather and climate. El Niño is defined as a warming of at least 0.5°C in sea surface temperatures in the east-central tropical Pacific, typically lasting 9-12 months. La Niña is the cooling phase, with sea surface temperatures dropping below normal by up to 4°C off the coasts of South America. Both phenomena alter weather worldwide, causing changes in temperature, precipitation, and storms. While they cannot be prevented, understanding their causes and effects can help communities better prepare for climate impacts and extreme weather.

6.5 - El Nino
ENSO refers to El Niño and La Niña phenomena in the Pacific Ocean that cause fluctuations in ocean temperatures from normal conditions. El Niño occurs when temperatures are higher than normal for sustained periods, while La Niña refers to lower than normal temperatures. These fluctuations originate off the west coast of South America and can impact global weather patterns, causing floods or droughts. The most recent El Niño occurred from September 2006 to early 2007.
El Nino
The document discusses the impacts of El Nino and La Nina conditions on weather patterns around the world. During El Nino, sea levels are higher in places like San Francisco due to changes in wind patterns. El Nino also contributes to more hurricanes in the eastern Pacific and less in the Atlantic on average, causing greater damage costs in the US. Tornado activity depends on the location of the polar jet stream, which shifts south during El Nino and north during La Nina. Satellites, ocean buoys, radiosondes and supercomputers are used to monitor conditions and predict El Nino events.

El Nino
El Niño Southern Oscillation (ENSO) is a climate pattern that occurs across the tropical Pacific Ocean approximately every 3 to 7 years, characterized by the warming of eastern Pacific Ocean waters and low atmospheric pressure in that region. El Niño events can have widespread global impacts, including severe droughts in some areas like the Philippines as well as floods in other regions such as California during the strong 1997-1998 El Niño when abnormally high sea levels caused hundreds of millions in flood damage in the San Francisco Bay area.
Unit 3 Lecture
This document discusses the El Niño Southern Oscillation (ENSO) phenomenon. It begins by explaining normal ocean surface and wind conditions in the Pacific and how El Niño events disrupt this pattern by weakening trade winds and shifting warm water eastward. Examples are given of the environmental and socioeconomic impacts of El Niño events around the world, such as increased flooding or drought. The document also notes that scientists are still learning about ENSO and factors like the location of sea surface warming may be important to predict weather effects, in addition to the temperature anomaly strength. ENSO has both a positive phase known as El Niño and negative phase called La Niña.
Presentation El Nino
El Niño and La Niña are climate phenomena in the Pacific Ocean that have worldwide impacts. El Niño occurs when ocean waters in the eastern Pacific warm significantly, affecting weather patterns globally. It typically happens every 2-7 years and causes drought in some areas and flooding in others. La Niña is the cooling phase, with colder than average waters in the eastern Pacific. While the exact causes are still being studied, theories involve changes in trade winds and ocean currents that create a feedback loop warming or cooling the waters in the eastern Pacific.

EL NINO - THE GLOBAL WEATHER PHENOMENON
LONDON, Dec. 26 (IPS) -- In March 1997, sea-surface temperatures in the Pacific Ocean began increasing -- the beginning of the "El Nino" weather system that, linked with the so-called "Southern Oscillation," has become notorious its global effects.
The El Nino of 1982-83 caused severe flooding and weather damage in Latin America as well as drought in parts of Asia. The last event, in 1991-92 brought severe drought to Southern Africa.
This year's El Nino is regarded by various experts as one of the most severe this century with record Pacific surface temperatures.
It is expected to continue well into 1998.
El Nino was the name given by the fishermen of northern Peru during the 19th century to describe the flow ofwarm equatorial waters southward around Christmas time. Normally the waters were cold and flowed from south to north.
But periodically the waters would reverse their flow and become warm. This caused the fish food chain to collapse as the warm current blocked the nutrient-rich cold water that rises from the bottom of the ocean. The fish died or moved away and catches would fall. This usually reached its peak around Christmas holiday, and the sailors named it "El Nino" (the Christ Child).
However, Peruvian scientists later linked more intense changes that took place every few years with catastrophic seasonal flooding along the normally arid coast.
At the beginning of the 20th century, British climatologist Gilbert Walker, head of the Indian Meteorological Service, began to investigate connections between the Asian monsoon and other climatic changes. He had been asked in 1904 to find a way to predict the pattern of India's monsoons after an 1899 famine caused by monsoon failure.
Unaware of El Nino, he discovered a periodic fluctuation of atmospheric pressure over the tropical Indo-Pacific region, which he called the Southern Oscillation (SO). When rainfall was sparse over northern Australia and Indonesia, pressure in that region was unusually high and wind patterns were changed.
At the same time, pressures were unusually low in the eastern South Pacific. Walker devised a "Southern Oscillation Index" (SOI), based on pressure differences between the two regions (east minus west) and in papers published during the 1920s and 1930s, he presented evidence for worldwide climatic changes associated with the SOI pressure "seesaw."
In the 1950s, the low-phase years of the SOI were found to corresponded ...

The document discusses the phenomena of El Niño and La Niña. El Niño occurs every 2-7 years, weakening trade winds and warming waters off South America. La Niña is the opposite, cooling waters off South America. El Niño lasts 9-12 months and brings drought to Australia/Indonesia but rain to North and South America. La Niña occurs every 3-4 years and lasts 3-4 years, bringing more rain to Australia/Indonesia. Both phenomena cause problems like floods, mudslides and climate alterations, but their effects can be reduced through prevention and disaster planning.
