An Example
Principal Component
Leading EOF Mode
q We
apply EOF analysis to a 50-year long time series of Pacific
SST variation from a model
simulation.
q The leading EOF mode shows a ENSO
SST pattern. The EOF analysis tells us that ENSO is the largest
process that produce SST variations in this 50-year long model
simulation.
qThe
principal component tells us which year has a El Nino or La Nina,
and how strong they are.
