Probably the most complete El Niño resource on the net is the El
Niño Theme Page, brought to you by the folks at the National Oceanic
and Atmospheric Administration. There is lots of good information here,
including real-time pictures of the tropical Pacific.
Another useful page that indexes El Niño resources on the net is the
El Niño Resources
page at the Center for Ocean/Atmosphere Prediction Studies, Florida State
University. Online text of a number of interesting articles is included.
Other Climate Forecast Centers
Another interesting site that has lots of general climate forecasting
information in addition to El Niño specific things is the IRI
(International Research Institute for Climate Prediction), here at the
University of California, San Diego. They have a page that compares the
predictions of three different
El Niño forecasts, the HCM (the model used here) included.
Experimental long-lead predictions of El Niño produced by various groups
are collected at the CPC into the Long-Lead
Forecast Bulletin. Our work is here as well as that of other researchers
in the field.
