Hovmollers of current OLR and SST anomalies (last 365 days)
Data filtered using C-LIM filter, based upon the result that the
eigenvectors of the system's dynamical evolution operator
separate into two distinct, but nonorthogonal, subspaces: one
governing the nearly uncoupled subseasonal dynamics ("internal"),
and the other governing the strongly coupled longer term dynamics
("coupled"). Note that no temporal filtering is applied.
