      Predicting and forecasting ENSO is essential to helping society prepare for the worst El Niño and La Niña events can bring. El Niño and La Niña prediction explained by climate scientists.

Forecasting uncertainty by ensemble prediction Global weather prediction: from days Seasonal to interannual prediction Decadal prediction and anthropogenic climate File Size: 1MB. NOAA Climate Prediction Center. Q What is El Niño? El Niño is the popular term for an El Niño-Southern Oscillation (ENSO) event. The most notable aspect of an El Niño is the migration of warm water from the western Pacific to the eastern Pacific, along the coasts of South America, Central America, and California. This warmer water.   Three different classes of numerical models successfully predicted the occurrence of the El Niño of at lead times of 3 to 9 months. Although the magnitude and timing of predicted ocean surface temperatures were not perfect, these results suggest that routine prediction of moderate to lare El Niño events is feasible. The key to the success of the models lies in recognizing or.

    In January NOAA's Climate Prediction Center officially announced that warming was being observed over the tropical Pacific which could lead to an El Niño by early spring. The announcement was supported by cloudiness and precipitation over the equatorial central Pacific observed for the first time since the El Niño episode.

Questions to Ponder and Discuss. Be sure you understand the science here; El Niño/southern oscillation is complex. Cane & Zebiak's prediction of the El Niño was announced at a press conference and in Nature on Ma In the following two weeks, at least 3 dozen newspapers carried articles about the prediction.

El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. El Nino is the “warm phase” of a larger phenomenon called the El Nino-Southern Oscillation (ENSO).

La Nina, the “cool phase” of ENSO, is a pattern that describes the unusual cooling of the region’s surface waters. The reported “cost” of El Niño events contributes greatly to misconceptions about the global climate effects and socioeconomic impacts of El Niño and La Niña.

The estimated costs of the two largest El Niño events of the twentieth century were 8–18 billion U.S. dollars (USD) for the /83 event (UCAR ; Sponberg ), and Cited by: The El Niño/La Niña Cycle (Tutorial) FAQ SST Niño Regions Global La Niña Impacts Global El Niño Impacts: NOAA/ National Weather Service National Centers for Environmental Prediction Climate Prediction Center Auth Road Camp Springs, Maryland Climate Prediction Center Web Team.

El Niño and La Niña are opposite phases of what is known as the El Niño-Southern Oscillation (ENSO) ENSO cycle is a scientific term that describes the fluctuations in temperature between the ocean and atmosphere in the east-central Equatorial Pacific (approximately between the International Date Line and degrees West).

El Niño and La Niña cause major changes to rainfall, temperature, and severe weather in many parts of the world, with impacts on health, agriculture, water resources, and ecosystems (e.g., McPhaden et al. ).Fortunately, the occurrence of El Niño/La Niña can usually be predicted two to three or more seasons in advance with modern operational prediction systems (e.g., Barnston et al Cited by: Reports to the Nation On Our Changing Planet.

Contents. El Niño–Southern Oscillation (ENSO) (ĕl nēn´yō), large-scale climatic fluctuation of the tropical Pacific Ocean and the overlying El Niño [Span.,=the child] is the South American term for the warm surface current that usually appears around Christmas in the Pacific off Ecuador and Peru and disappears by the end of March, but every two to seven years it persists for up to.

The impacts of El Niño upon climate in temperate latitudes show up most clearly during wintertime. For example, most El Niño winters are mild over western Canada and parts of the northern United States, and wet over the southern United States from Texas to Florida.

El Niño affects temperate climates in other seasons as well. El Niño and La Niña are the warm and cool phases of a recurring climate pattern across the tropical Pacific—the El Niño-Southern Oscillation, or “ENSO” for short. The pattern can shift back and forth irregularly every two to seven years, and each phase triggers predictable disruptions of temperature, precipitation, and winds.

By understanding the weather impacts of the different phases of ENSO climatologists and meteorologists can make fairly decent forecasts of temperatures and precipitation for a month or season. The Climate Prediction Center creates the maps below to show the forecast over the next three months.

In recent decades, a distinctly different type of El Niño has emerged. 'Normal' El Niños are climate events associated with anomalous warming in the eastern Pacific, and climatic consequences Cited by: El Niño represents the dominant year-to-year climate variability in the tropical Pacific and exerts a wide range of influences over much of the globe can trigger abnormal weather conditions, such as drought, in regions far from the tropics 2,3 and it impacts greatly on marine ecosystems, including those associated with productive fisheries largest recorded El Niño event of /98 Cited by: 6.

Despite the strong signal of El Niño/Southern Oscillation (ENSO) events on climate in the Indo-Pacific region, models linking ENSO-based climate variability to seasonal rice production and food security in the region have not been well developed or widely used in a policy context. This study successfully measures the connections among sea surface temperature anomalies (SSTAs), rainfall, Cited by: A new study takes a historical look at the climate phenomena, and charts how society’s need to better prepare for El Niño has paved the way for modern climate prediction.

An age old fascination. Every five years or so, a change in the winds causes a shift to warmer than normal ocean temperatures in the equatorial Pacific Ocean.

This shift is. This goes along with a prediction made last week by the U.S. Climate Prediction Center. "As the article notes, if this does happen, we will likely see a new global temperature record in   NOAA.

For this reason, researchers have begun to take into account a much more global area of climate data than previously considered with the hopes of predicting El Niño or La Niña.
