Why Predict Climate? The march of the seasons imparts a rhythm to life on Earth. Over much of the world, climate swings like a pendulum between summer and winter. Even in the tropics, where the weather is warm year round, rainy seasons, known as monsoons, alternate with dry seasons and each has its own distinct pattern of prevailing winds.

The Niño index is computed as the monthly SST anomaly averaged over the region 5°N-5°S, °W°W. The SOI is normalized by its standard deviation. Values between ±° on either graph are considered ENSO-neutral. Periods in red represent El Niño conditions and in blue La Niña conditions. Dear stakeholders, NWS is working on improving approaches for communication of the NWS climate products.

Under this project Climate Prediction Center (CPC) is currently gathering feedback on potential changes to the headlines used in their El Niño-Southern Oscillation (ENSO) Alert System using this online survey. Please complete this survey and send it to your partners — we need as large a sample of NWS . 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. Nino Index (ONI) [3 month running mean of ERSST.v5 SST anomalies in the Nino region (5N-5S, W)]. For historical purposes, periods of below and above normal SSTs are colored in blue and red when the threshold is met for a minimum of 5 . The Climate Prediction Center (CPC) Merged Analysis of Precipitation (CMAP) data are used to verify the climate model’s performance for the period – The data are produced by merging rain gauge data, five kinds of satellite estimates, and a numerical model predictions(Xie and Arkin ).Cited by:
The IRI’s definition of El Niño, like NOAA/Climate Prediction Center’s, requires that the SST anomaly in the NINO region (5S-5N; WW) exceed C. Similarly, for La Niña, the anomaly must be C or less. The climatological probabilities for La Niña, neutral, and El Niño conditions vary seasonally, and are shown in a table.

The ability to anticipate how climate will change from one year to the next will lead to better management of agriculture, water supplies, fisheries, and other resources.
