Scripps News (18 VI 97 is reporting that the U.S. National Oceanographic
and Atmospheric Administration's Climate Prediction Center now is
suggesting that the upcoming El Nino/Southern Oscillation (ENSO) event may
be a big one, approaching the 1982-1983 event in  scope.

Since a major ENSO can affect rainfall, currents, temperature and winds
across most continents and oceans, researchers conducting single-year
studies should be aware that this may well not be a 'normal' year. Those
conducting long-term studies or working as part of a network may wish to
set up additional measurements to 'capture' this event more fully.  Those
monitoring diseases should consider that rodent and arthropod populations
may respond to drought or increased rainfall conditions characteristic of
ENSO conditions in their region.

A description of some typical effects can be found at
Additional documentation of the 1982 ENSO can be found in Glynn PW 1990.
Global ecological consequences of the 1982-83 El Nino-Soputhern
oscillation, Elsevier, New York.

For more information
Climate Prediction Center  <>  (see especially
Climate Diagnostics Bulletin, click analysis and monitoring) provides all
sorts of interesting ENSO climate data in near 'real time'.
