The Pacific multidecadal climate variability (PMV) is
an important
phenomenon that has significant economic and
societal impact. It is
not only of considerable scientific interest but also
a central
component for potential long-term climate prediction.
In this study,
the PMV in the Community Climate System Model version
3 (CCSM3)
is investigated with a combined statistical and
dynamical approach.
Specifically designed sensitivity experiments are
performed to
explicitly identify the origin of the PMV. The
results support a North
Pacific origin for the PMV, with the ...
