Contemporaneous Correlations
We focus on the JJA and SON seasons. Fig. 1
indicates the contemporaneous linear correlation
between anomalous rainfall in NVE and SST
anomalies. For the JJA season, the figure
indicates the only statistically significant
correlations are found in the tropical North Atlantic
and Caribbean, while negative correlations, mainly
in the eastern tropical Pacific and Caribbean,
dominate during SON. The boxes in Fig. 1 indicate
the Nino 3 region in the eastern Pacific and a
region in the tropical North Atlantic that we will call
the NATL region, after Enfield (1996).
