The influence of volcanic eruptions on weather regimes over the North Atlantic simulated by ECHAM5/MPI-OM ensemble runs from 800 to 2000 CE

Guðlaugsdóttir, Hera; Steen-Larsen, H.C.; Sjolte, J.; Masson-Delmotte, V.; Werner, M.; Sveinbjörnsdóttir, Árný (Elsevier BV, 2018-11)

The volcanic fingerprint on the winter North Atlantic atmospheric circulation and climate is analyzed in six ensemble runs of ECHAM5/MPI-OM covering 800–2000 CE, both for equatorial and Northern Hemisphere (NH) eruptions. Large volcanic eruptions ...
North Atlantic weather regimes in δ18O of winter precipitation: isotopic fingerprint of the response in the atmospheric circulation after volcanic eruptions

Guðlaugsdóttir, Hera; Sjolte, Jesper; Sveinbjörnsdóttir, Árný; Werner, Martin; Steen-Larsen, Hans Christian (Informa UK Limited, 2019-07-19)

Equatorial volcanic eruptions are known to impact the atmospheric circulation on seasonal time scales through a strengthening of the stratospheric zonal winds followed by dynamic ocean-atmosphere coupling. This emerges as the positive phase of the North ...
