  • Role of atmosphere-ocean interactions in supermodeling the tropical Pacific climate 

    Shen, Mao-Lin; Keenlyside, Noel; Bhatt, Bhuwan Chandra; Duane, Gregory (AIP Publishing, 2017-12-29)
    The supermodel strategy interactively combines several models to outperform the individual models comprising it. A key advantage of the approach is that nonlinear improvements can be achieved, in contrast to the linear ...

    Carmack, Eddy; Polyakov, Igor V.; Padman, Laurie; Fer, Ilker; Hunke, Elizabeth Clare; Hutchings, Jennifer J.; Jackson, Jennifer M.; Kelley, Daǹ E.; Kwok, Ronald; Layton, Chantelle; Melling, Humfrey; Perovich, Donald K.; Persson, Ola G.; Ruddick, Barry; Timmermans, Mary Louise E.; Toole, John M.; Ross, Tetjana; Vavrus, Steve J.; Winsor, Peter R. (American Meteorological Society, 2015)
    The loss of Arctic sea ice has emerged as a leading signal of global warming. This, together with acknowledged impacts on other components of the Earth system, has led to the term “the new Arctic.” Global coupled climate ...

  • Modulation of the Aleutian–Icelandic low seesaw and its surface impacts by the Atlantic Multidecadal Oscillation 

    Li, Fei; Orsolini, Yvan; Wang, Huijun; Gao, Yongqi; He, Shengping (Springer, 2018-01)
    Early studies suggested that the Aleutian–Icelandic low seesaw (AIS) features multidecadal variation. In this study, the multidecadal modulation of the AIS and associated surface climate by the Atlantic Multidecadal ...

  • Utilizing Solar Vapour Energy by Use of Nanofluids in a Direct Absorption Solar Collector 

    Ulset, Edda Torsdottir (The University of Bergen, 2018-01)
    Traditional solar thermal collectors and photovoltaic (PV) systems suffer from low energy conversion efficiencies. This is mainly due to high thermal losses from overheated absorber plates or solar cells. For steam ...

  • Regional, seasonal, and predictable Arctic sea ice change 

    Onarheim, Ingrid Husøy (The University of Bergen, 2017-12-07)
    The loss of Arctic sea ice is one of the most prominent and best quantified indicators of ongoing global climate change. Satellite passive microwave observations since 1979 indicate significant negative sea ice extent ...

  • Toward an ice-free Barents Sea 

    Onarheim, Ingrid Husøy; Årthun, Marius (American Geophysical Union, 2017)
    Arctic winter sea ice loss is most pronounced in the Barents Sea. Here we combine observations since 1850 with climate model simulations to examine the recent record low winter Barents Sea ice extent. We find that the ...
