From: Rapid global ocean-atmosphere response to Southern Ocean freshening during the last glacial
Modelled global atmospheric propagation of a Southern Ocean freshwater flux during the last glacial period. Geopotential height and wind anomalies at 850 hPa a 300 hPa b and global annual rainfall anomalies c. Zonally averaged global temperature anomalies for the atmosphere d reflect the characteristic pattern of westerly propagating Rossby waves. a–d produced from CSIRO Mk3L ensemble simulations of a 338-year duration freshwater flux of 0.54 Sv into the Weddell and Ross Seas. The schematic in e shows an idealized extratropical Rossby wave train (solid black arrows) associated with low (blue) and high (red) pressure systems generated by anomalous equatorial Pacific upper-level divergence27, 28.
