• Competing Effects of Droplet Sedimentation and Wind Shear on Entrainment in Stratocumulus 

      Schulz, BernhardORCIDiD; Mellado, Juan PedroORCIDiD (Journal of Advances in Modeling Earth Systems, 2019)
      The joint effect of droplet sedimentation and wind shear on cloud top entrainment in stratocumulus is investigated with direct numerical simulations. Although it is well understood that droplet sedimentation weakens ...
    • Evolution and Features of Dust Devil‐Like Vortices in Turbulent Rayleigh‐Bénard Convection—An Experimental Study 

      Kaestner, ChristianORCIDiD; Schneider, Julien David; du Puits, Ronald (Journal of Geophysical Research: Atmospheres, 2023-01-18)
      We present an experimental study simulating atmospheric dust devils in a controlled laboratory experiment. The experimental facility, called the “Barrel of Ilmenau” (www.ilmenauer-fass.de) represents a classical Rayleigh‐Bénard ...
    • High‐Resolution Observations of Turbulence Distributions Across Tropopause Folds 

      Söder, JensORCIDiD; Zülicke, ChristophORCIDiD; Gerding, MichaelORCIDiD; Lübken, Franz‐Josef (Journal of Geophysical Research: Atmospheres, 2021-03-22)
      In this study, we interpret two vertical turbulence measurements. We acquired these uninterrupted high‐resolution dissipation rate profiles with the balloon‐borne instrument LITOS (Leibniz Institute Turbulence Observations ...
    • Influence of Radiation on Evaporation Rates: A Numerical Analysis 

      Heck, K.; Coltman, E.ORCIDiD; Schneider, J.ORCIDiD; Helmig, R.ORCIDiD (Water Resources Research, 2020-10-02)
      We present a fully coupled soil‐atmosphere model that includes radiation in the energy balance of the coupling conditions between the two domains. The model is able to describe evaporation processes under the influence of ...
    • On the Along‐Slope Heat Loss of the Boundary Current in the Eastern Arctic Ocean 

      Schulz, KirstinORCIDiD; Janout, MarkusORCIDiD; Lenn, Yueng‐Djern; Ruiz‐Castillo, EugenioORCIDiD; Polyakov, IgorORCIDiD; Mohrholz, VolkerORCIDiD; Tippenhauer, SandraORCIDiD; Reeve, Krissy AnneORCIDiD; Hölemann, JensORCIDiD; Rabe, BenjaminORCIDiD; Vredenborg, MyrielORCIDiD (Journal of Geophysical Research: Oceans, 2021-02-15)
      This study presents recent observations to quantify oceanic heat fluxes along the continental slope of the Eurasian part of the Arctic Ocean, in order to understand the dominant processes leading to the observed along‐track ...
    • The Role of Turbulence in Fueling the Subsurface Chlorophyll Maximum in Tidally Dominated Shelf Seas 

      Becherer, JohannesORCIDiD; Burchard, HansORCIDiD; Carpenter, Jeffrey R.ORCIDiD; Graewe, Ulf; Merckelbach, Lucas M. (Journal of Geophysical Research: Oceans, 2022-08-25)
      Glider observations show a subsurface chlorophyll maximum (SCM) at the base of the seasonal pycnocline in the North Sea during stable summer conditions. A colocated peak in the dissipation rate of turbulent kinetic energy ...
    • The Two‐Energies Turbulence Scheme Coupled to the Assumed PDF Method 

      Bašták Ďurán, IvanORCIDiD; Sakradzija, MirjanaORCIDiD; Schmidli, JuergORCIDiD (Journal of Advances in Modeling Earth Systems, 2022-05-14)
      An update of the two‐energy turbulence scheme is presented, the 2TE + APDF scheme. The original version of the two‐energy scheme is able to successfully model shallow convection without the need of an additional parameterization ...
