This radio broadcast describes the El Nino climate phenomena of 1998 and how the El Nino weather pattern caused untold damage and unusual climate effects in 1998. This sound clip lasts 3 minutes and 26 seconds. Full description.

El Nino is a disruption of the ocean-atmosphere system in the Tropical Pacific having important consequences for weather and climate around the globe. This webpage provides a portal to a wide array of information about El Nino. Types of information include forecasts, observations, research, animations, data, maps, and impacts. There are links to many types of educational resources such as classroom ... Full description.

This webpage is part of NASA's Classroom of the Future program. It provides background information about how ocean temperatures, currents, and atmospheric conditions combine to produce an El Nino event. The site features text, scientific illustrations, a glossary, and links to other Classroom of the Future pages. Full description.

This article discusses how graphic representations of data helped make recognizing patterns easier. The use of maps of surface temperature in the Pacific Ocean to detect El Nino events is cited as an example. Full description.

This radio broadcast reports that a lakebed in Ecuador contains a geologic record of the past 15,000 years of El Nino activity. Evidently, El Nino phenomena were not always so severe. Some scientists have theorized that as El Nino got worse, it actually affected the development of ancient cultures. This sound clip lasts 3 minutes and 38 seconds. Full description.

A view of El Nino and La Nina through Pacific sea surface temperature anomalies from 1998 through 2001. Full description.

A comparison of the Pacific sea surface temperature anomaly during the El Nino of 1982-1983 with that of 1997, as measured by NOAA AVHRR. This animation ends with a zoom into the 1982-1983 data. Full description.

This forty-eight minute radio broadcast discusses the drought of Spring 2002 in the United States and its possible consequences, such as low water levels altering the biology of the Great Lakes. The show also discusses the causes of drought, long-range climate forecasts, and the connection to El Nino. Full description.

El Nino Sea Surface Wind Anomaly in the Pacific for January 1997 through October 1997 as measured by DMSP SSM-I Full description.

A comparison of the Pacific sea surface temperature anomaly during the El Nino of 1982-1983 with that of 1997-1998, as measured by NOAA AVHRR Full description.
