Hovmollers of current OLR, zonal wind, 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.
