The National Oceanic and Atmospheric Administration (NOAA) and the National Centers for Environmental Predication (NCEP) have made available this excellent learning resource, the ENSO Cycle Website. Graphs, images, photographs, and brief summaries explicate topics such as the Mean state of the Ocean and Atmosphere across the Tropical Pacific, the ENSO Cycle, El Nino, La Nina, and the Evolution of the ENSO Cycle. Visitors can view spectacular photographs of wind gusts, localized thunderstorms and tornadoes, fires, and floods in the Climate Variability section.
