• Coupled stratosphere-troposphere-Atlantic multidecadal oscillation and its importance for near-future climate projection 

      Omrani, Nour-Eddine; Keenlyside, Noel Sebastian; Matthes, Katja; Boljka, Lina; Zanchettin, Davide; Jungclaus, Johann H.; Lubis, Sandro W. (Journal article; Peer reviewed, 2022)
      Northern Hemisphere (NH) climate has experienced various coherent wintertime multidecadal climate trends in stratosphere, troposphere, ocean, and cryosphere. However, the overall mechanistic framework linking these trends ...
    • Key Role of the Ocean Western Boundary currents in shaping the Northern Hemisphere climate 

      Omrani, Nour-Eddine; Ogawa, Fumiaki; Nakamura, Hisashi; Keenlyside, Noel; Lubis, Sandro W.; Matthes, Katja (Peer reviewed; Journal article, 2019)
      The individual impact of North Atlantic and Pacific Ocean Western Boundary Currents (OWBCs) on the tropospheric circulation has recently been studied in depth. However, their simultaneous role in shaping the hemisphere-scale ...
    • Solar forcing synchronizes decadal North Atlantic climate variability 

      Thiéblemont, Rémi; Matthes, Katja; Omrani, Nour-Eddine; Kodera, Kunihiko; Hansen, Felicitas (Peer reviewed; Journal article, 2015-09-15)
      Quasi-decadal variability in solar irradiance has been suggested to exert a substantial effect on Earth’s regional climate. In the North Atlantic sector, the 11-year solar signal has been proposed to project onto a pattern ...
