Fig. 3: Skin temperature and meridional circulation anomalies distribution associated with the SWIO index.
From: Role of Antarctic ozone in shaping East Asian summer precipitation variability

A Vertical velocity anomalies (shadings; 10-3 Pa/s) and meridional circulation anomalies (grey and purple arrows) regressed against the SWIO index, averaged over 60°–120°E. The SKTAs during (B) MAM and (C) JJA regressed against boreal spring SWIO index (shadings; K). Black stippling represents significance above the 90% confidence level. IPSKTI is defined based on the red rectangular region. Black stippling and purple arrows represent significance above the 90% confidence level.
