  • Growth and decay of a convective boundary layer over a surface with a constant temperature 

    van Heerwaarden, Chiel; Mellado González, Juan Pedro (2016-05-05)
    Article
    Open Access
    The growth and decay of a convective boundary layer (CBL) over a surface with a constant surface temperature that develops into a linear stratification is studied, and a mathematical model for this system is derived. The ...

  • Analysis of external and global intermittency in the logarithmic layer of Ekman flow 

    Ansorge, Cedrick; Mellado González, Juan Pedro (2016-10-25)
    Article
    Open Access
    Existence of non-turbulent flow patches in the vicinity of the wall of a turbulent flow is known as global intermittency. Global intermittency challenges the conventional statistics approach when describing turbulence ...

  • Reconciling estimates of the ratio of heat and salt fluxes at the ice-ocean interface 

    Keitzl, Thomas; Mellado González, Juan Pedro; Notz, Dirk (Wiley, 2016-12-02)
    Article
    Open Access
    The heat exchange between floating ice and the underlying ocean is determined by the interplay of diffusive fluxes directly at the ice–ocean interface and turbulent fluxes away from it. In this study, we examine this ...

  • Cloud-top entrainment in stratocumulus clouds 

    Mellado González, Juan Pedro (2017-01-01)
    Article
    Restricted access - publisher's policy
    Cloud entrainment, the mixing between cloudy and clear air at the boundary of clouds, constitutes one paradigm for the relevance of small scales in the Earth system: By regulating cloud lifetimes, meter- and submeter-scale ...

  • Reduction of the entrainment velocity by sedimentation in stratocumulus 

    de Lozar, Alberto; Mellado González, Juan Pedro (2017-03-01)
    Article
    Open Access
    The effect of sedimentation on stratocumulus entrainment is investigated using direct numerical simulations of a cloud-top mixing layer driven by radiative and evaporative cooling. The simulations focus on the meter and ...

  • Moisture statistics in free convective boundary layers growing into linearly stratified atmospheres 

    Mellado González, Juan Pedro; Puche, Marc; van Heerwaarden, Chiel (2017-07-27)
    Article
    Open Access
    We use dimensional analysis and direct numerical simulations to characterize specific humidity statistics in the equilibrium (quasi-steady) entrainment regime of cloud-free convective boundary layers that grow into ...

  • MicroHH 1.0: a computational fluid dynamics code for direct numerical simulation and large-eddy simulation of atmospheric boundary layer flows 

    van Heerwaarden, Chiel; van Stratum, Bart; Heus, Thijs; Gibbs, Jeremy; Fedorovich, Evgeni; Mellado González, Juan Pedro (2017-08-28)
    Article
    Open Access
    This paper describes MicroHH 1.0, a new and open-source (www.microhh.org) computational fluid dynamics code for the simulation of turbulent flows in the atmosphere. It is primarily made for direct numerical simulation but ...

    Català Sabaté, Martí; Alonso Muñoz, Sergio; Álvarez Lacalle, Enrique; López Codina, Daniel; Cardona Iglesias, Pere Joan; Prats Soler, Clara (2020-05-19)
    Article
    Open Access
    Covid-19 appearance and fast spreading took by surprise the international community. Collaboration between researchers, public health workers and politicians has been established to deal with the epidemic. One important ...
