What El Niño Could Mean For 2015-16 by Sarah Beecroft Sept 21 2015

El Niño is defined by prolonged warming in the Pacific Ocean sea surface temperatures when compared with the average value.

The US NOAA definition is a 3-month average warming of at least 0.5 °C (0.9 °F) in a specific area of the east-central tropical Pacific Ocean; other organizations define the term slightly differently.

Typically, this anomaly happens at irregular intervals of two to seven years, and lasts nine months to two years.

The average period length is five years.

When this warming occurs for seven to nine months, it is classified as El Niño "conditions"; when its duration is longer, it is classified as an El Niño "episode".

NOAA/ National Weather Service

NOAA's National Climatic Data Center is the world's largest repository of weather and climate data and information.

NOAA Data sources are as varied as paleoclimatic samples to handwritten observations to satellite and radar imagery less than an hour old.

The Center has the primary mission of preserving these data for future generations as well as making them available to the public, business, industry, government, and researchers.

Increasing global temperature is only one element of observed global climate change. Precipitation patterns are also Intergovernmental Panel on Climate Change (IPCC) changing; storms and other extremes are changing as well.

Internationally; under the auspices of the United Nations (UN), World Meteorological Organization (WMO), and the United Nations Environment Program (UNEP), is the most senior and authoritative body providing scientific advice to global policy makers.
