Fig. 6: Relationship between SPCZ convection and atmospheric blocking events over coastal West Antarctica.

Composite differences between period-2 and period-1 in (a) daily precipitation and (b) daily OLR, averaged over the preceding 40 days of the upper-quartile blocking events. The black dots outline areas where the differences are significant at a 99% level. The thick black rectangle outlines the “SPCZ box”.
