Composite differences between negative and positive PDO-phases from the Natural CESM experiment.
Top Mean differences for SSTs (colour shading) and low-level (850 hPa) wind speeds (arrows). Bottom Mean differences in the deep convection frequency (colour shading). Stippling indicates the 95% statistic significance level, with autocorrelation effects taken into account.
