    Determination of eddy dissipation rate by Doppler lidar in Reykjavik, Iceland 
    Yang, Shu; Petersen, Guðrún Nína; von Löwis, Sibylle; Preißler, Jana; Finger, David C. (Wiley, 2020-09)
    The temporal and spatial scale of atmospheric turbulence can be highly dynamic, requiring sophisticated methods for adequate detection and monitoring with high resolution. Doppler light detection and ranging (lidar) systems have been widely used to ...

    Flow distortion recorded by sonic anemometers on a long-span bridge: Towards a better modelling of the dynamic wind load in full-scale 
    Cheynet, Etienne; Jakobsen, Jasna Bogunović; Snaebjornsson, Jonas Thor (Elsevier BV, 2019-06)
    The turbulent wind field around a suspension bridge deck is studied using eleven months of full-scale records from sonic anemometers mounted above the girder. Using the mean and turbulent velocity characteristics, we demonstrate that the bridge structure ...

    The influence of terrain on the mean wind flow characteristics in a fjord 
    Cheynet, Etienne; Liu, Shengnan; Ong, Muk Chen; Bogunović Jakobsen, Jasna; Snaebjornsson, Jonas Thor; Gatin, Inno (Elsevier BV, 2020-10)
    Flow conditions in complex terrains such as fjords are highly three-dimensional and thus not properly captured by the wind flow models developed for homogenous terrains. In the present study, we explore the potential of computational fluid dynamics ...

    Investigation of Vorticity during Prevalent Winter Precipitation in Iran 
    Rousta, Iman; Javadizadeh, Farshad; Dargahian, Fatemeh; Olafsson, Haraldur; Shiri-Karimvandi, Amin; Vahedinejad, Sayed Hossein; Doostkamian, Mehdi; Monroy Vargas, Edgar Ricardo; Asadolahi, Anayat (Hindawi Limited, 2018-09-30)
    In this study, precipitation data for 483 synoptic stations, and the U&V component of wind and HGT data for 4 atmospheric levels were respectively obtained from IRIMO and NCEP/NCAR databases (1961–2013). The precipitation threshold of 1 mm and a minimum ...

    Measurements of Surface-Layer Turbulence in a Wide Norwegian Fjord Using Synchronized Long-Range Doppler Wind Lidars 
    Cheynet, Etienne; Jakobsen, Jasna; Snaebjornsson, Jonas Thor; Mann, Jakob; Courtney, Michael; Lea, Guillaume; Svardal, Benny (MDPI AG, 2017-09-21)
    Three synchronized pulsed Doppler wind lidars were deployed from May 2016 to June 2016 on the shores of a wide Norwegian fjord called Bjornafjord to study the wind characteristics at the proposed location of a planned bridge. The purpose was to investigate ...
