Figure 24: Percentage of variance for DJF due to SSTs based on analysis of surface
pressure from a 6-member ensemble of 45-year integrations of the UKMO GeM made
with observed specified SSTs. Top panels: seasonal mean fields. Bottom panels: running
lO-year average of seasonal mean fields. (D. Rowell, personal communication).
