USA Today presents a regularly updated archive of El Nino and La Nina stories, descriptions, and overviews. An excellent resource to learn what these storms are, how they began, and their onging history.

Young scholars explore NOAA and the Climate Data Center to gather data about El Nino. Then they interpret a series of maps to describe the key changes in climate conditions during El Nino and La Nina.

La Nina is characterized by unusually cold ocean temperatures in the equatorial Pacific, as compared to El Nino, which is characterized by unusually warm ocean temperatures in the equatorial Pacific. Find more general info, Forecasts,...

Get an overview of El Nino and La Nina. Look up present conditions or find out the impact these weather phenomena have had in the past. This is a very comprehensive resource for any question you might have on these cyclical weather...

Sort pictures of El Nino and La Nina conditions based on sea-surface temperatures.

The National Oceanic and Atmospheric Administration (NOAA) sponsors this El Nino and La Nina resource site that features current and historic information about these weather systems with diagrams.

Through data analysis and observations of patterns, students learn about normal seasonal sea surface temperature variation as well as extreme variation, as in the case of El Nino and La Nina events, in the equatorial Pacific Ocean.

You can link to the anatomy of El Nino, chasing El Nino, and El Nino's reach. There is a resource page and a search page.

Resource features real-time data from moored ocean buoys for improved detection, understanding, and prediction of El Nino and La Nina with diagrams.

Do you know what happens during a typical El Nino? This overview provides a description, characteristics, and animated maps showing sea surface temperature changes during past El Nino events.

This site introduces you to one of the most ambitious projects now studying the influence of the ocean on climate. Links are available to related sites and to sources of real-time data.

The story of La Nina in two parts. El Nino began and then La Nina takes over.

Provides information for ten day and two-week outlooks on temperature, precipitation, and soil moisture conditions throughout the world. Offers information on climate topics including El Nino and La Nina.

In this 3-part lesson plan, students explore California climate and factors that are leading to changes within this climate system. Students begin by exploring California's climate and the state's topography. Next, they investigate...
