Fig. 6: HIST period responses to IOD-East and IOD-West events resemble HIST and 21C responses respectively.
From: Climate change alters the Indian Ocean Dipole and weakens its North Atlantic teleconnection

Panels a, b show pIOD minus nIOD composite differences for MSLP and 250 hPa meridional wind based on eastward-shifted IOD events; panels c, d show corresponding differences for westward-shifted IOD events. Stippling shows significance at the 5% level.
