| 1) (a) SLP and (b) SLA regressed onto the SAM index for the period 1993-2005. (c) SLP and (d) SLA regressed onto the ENSO index for the period 1993-2005. Patterns below the 80% significance limit are blanked. The black lines show the mean SAF and PF positions. |

| 2) Panel (a): Covariance of the meridional position of the PF and the SAM (black) or ENSO (gray) indexes as a function of the longitude. Bold line shows a significance above the 95% confidence level. Panel (b): Same as panel (a) but for the high frequency band of the signal (less than 3 months). Panel (c): Same as panel (a) but for the low frequency band of the signal (more than one year). |
