Use the resources listed below to help you complete this activity.

 

To learn more about this topic, visit the following web sites:


El Nino and non-El Nino Conditions

"El Nino Theme Page" - TOGA - TAO, NOAA
Page contains links to cover a wide range of topics, including definitions of El Nino and La Nina, impacts of El Nino, predicting El Nino, 3-D animations of El Nino temperatures, and information on finding El Nino data.

"El Nino: Facts, figures, images, and predictions"
Mariner, V.A., 1998, College and Research Libraries,
v. 59, no. 9
Online article explains how to use the Internet to research El Nino. Includes multiple links on El Nino, grouped by "topic", including the current status of El Nino, forecasting El Nino, El Nino information from the mass media, images of El Nino, and more.

"NOAA El Nino Page"
Site contains an image of current sea-surface temperature anomalies which is updated regularly. Site also contains links to El Nino images and information, including a list of El Nino-related web sites.

"El Niño and La Niña Tracing the Dance of Ocean and Atmosphere" - National Academy of Sciences

The Southern Oscillation

"El Nino/La Nina Home" - NOAA Climate Prediction Center
Includes links to information on ENSO forecasts, an "expert assessment" (updated weekly), ENSO figures (updated weekly), and a list of FAQ. Also includes an online tutorial which contains numerous color images.

"CDC's El Nino/Southern Oscillation (ENSO) Information" - NOAA/CIRES Climate Diagnostics Center
This site links to information on the science behind ENSO, current ocean/atmosphere conditions, impacts of ENSO on climate, forecasts, current research, and links to educational resources.

The Equatorial Pacific and El Nino

El Nino Watch - NASA
Find images of the Pacific from space (including sea surface images, water vapor, SST anomalies, surface winds, El Nino animations), an ENSO "primer" (a thorough review of ENSO, presented in audiovisual format with color images and text), links to related NASA research projects, and more.

"TOGA-TAO and the 1991-93 El Nino-Southern Oscillation Event" - McPhaden, M.J., NOAA/PMEL
Online article examines data collected by the TOGA-TAO program. Includes color data images.

Cause and Effect - El Nino

"USGS New and Information on El Nino" - USGS
This site focuses on the impacts of El Nino, including coastal erosion, flooding, landslides, storms, and climate change. Click on link to open the article of interest.

"List of Impacts and Prediction Benefits" - PMEL (NOAA)
Click on link to find further information on the impacts of El Nino, such as El Nino and tornado occurances, El Nino and hurricane frequency, coral reef bleaching, El Nino and marine fish and birds, and more.

"El Nino Sea-Level Rise Wreaks Havoc in California's San Fransico Bay Region" - USGS Fact Sheet 175-99
Online fact sheet (can also be downloaded and printed in PDF format) looks at the impact of the 1997-1998 El Nino event on the Bay area. Site includes damage photos, sea level data, upwelling images, and an explanation of Kelvin waves and their impact.

"El Nino Storms Erode Beaches on Monterey Bay, California" - USGS Fact Sheet 026-00
Two-page fact sheet reviews the relationship between El Nino and coastal erosion on Monterey Bay, California. Includes color images.

"El Nino and La Nina Resources on the Internet - Effects" - COAPS
Site lists several online articles which detail the impact of El Nino on the U.S. and world.
