Re: Correlations of Rainfall and Global SST's

See: http://www.ncl.ucar.edu/Applications/indices.shtml
      indices_soi_2

Variables like temperature and pressure are spatially
and temporally correlated. In this case use of a monthly time
series from an individual station/grid point may be 'ok'
for a corelation map. This is definitely not true
for precititation. It would be better to average the values.
