Arctic sea ice and Eurasian climate: A review
Gao, Yongqi; Sun, Jianqi; Li, Fei; He, Shengping; Sandven, Stein; Yan, Qing; Zhang, Zhongshi; Lohmann, Katja; Keenlyside, Noel; Furevik, Tore; Suo, Lingling (Peer reviewed; Journal article, 2014-11-28)The Arctic plays a fundamental role in the climate system and has shown significant climate change in recent decades, including the Arctic warming and decline of Arctic sea-ice extent and thickness. In contrast to the ... -
Using simulations of the last millennium to understand climate variability seen in palaeo-observations: Similar variation of Iceland-Scotland overflow strength and Atlantic Multidecadal Oscillation
Lohmann, Katja; Mignot, Juliette; Langehaug, Helene Reinertsen; Jungclaus, Johann H.; Matei, Daniela; Otterå, Odd Helge; Gao, Yongqi; Mjell, Tor Lien; Ninnemann, Ulysses Silas; Kleiven, Helga Flesche (Peer reviewed; Journal article, 2015-02-10)A recent palaeo-reconstruction of the strength of the Iceland–Scotland overflow during the last 600 years suggests that its low-frequency variability exhibits strong similarity with palaeo-reconstructions of the Atlantic ... -
Water mass transformation and the North Atlantic Current in three multi-century climate model simulations
Langehaug, Helene Reinertsen; Rhines, Peter B.; Eldevik, Tor; Mignot, Juliette; Lohmann, Katja (Journal article, 2012-11)The warm and saline Subtropical Water carried by the North Atlantic Current undergoes substantial transformation on its way to higher latitudes as heat is released from ocean to atmosphere. The geographical distribution ...
