Figure 7
(a,c) 5-yr mean SLP anomalies (in hPa) observed during 1999–2003 and 2004–2008, respectively. The black boxes indicate the region where the SWIO index was calculated. (b,d) Same as in (a,c), but for the reforecast experiments initialized from March 1st 1999. Here we show 12 ensemble mean SLP anomalies. The maps were generated using Grid Analysis and Display System (GrADS) Version 2.1.a3 (http://cola.gmu.edu/grads/downloads.php).
