    • Evolution of the turbulence during the afternoon transition of the convective boundary layer: a spectral analysis 

      Darbieu, Clara; Lohou, Fabienne; Lothon, Marie; Couvreux, Fleur; Pino González, David; Durand, Pierre; Blay Carreras, Estel; Vilà Guerau de Arellano, Jordi (American Meteorological Society, 2014)
      Conference report
      Open Access
      The transition from a well-mixed convective boundary layer to a residual layer overlying a stabilized nocturnal layer raises several issues, which remain difficult to address from both modeling and observational perspectives. ...

      The Chemistry-Aerosol Mediterranean Experiment (ChArMEx; http://charmex.lsce.ipsl.fr) is a collaborative research program federating international activities to investigate Mediterranean regional chemistry-climate interactions. ...
    • Study of a prototypical convective boundary layer observed during BLLAST: contributions by large-scale forcings 

      Pietersen, Henk; Vilà Guerau de Arellano, Jordi; Augustin, P; van de Boer, Anneke; de Coster, Olivier; Delbarre, Hervé; Durand, Pierre; Fourmentin, M; Gioli, Beniamino; Hartogensis, Oskar; Lohou, Fabienne; Lothon, Marie; Ouwersloot, Huug; Pino González, David; Reuder, Joachim (2015-04-24)

      Open Access
      We study the influence of the large-scale at- mospheric contribution to the dynamics of the convective boundary layer (CBL) in a situation observed during the Boundary Layer Late Afternoon and ...
    • Studying the Boundary Layer Late Afternoon and Sunset Turbulence (BLLAST) 

      Vilà-Guerau de Arellano, Jordi; Pino González, David; Pardyjak, Erick; Mahrt, Larry; Lohou, Fabienne; Jonker, Harm J. J.; Gioli, Beniamino; Gibert, Fabien; Durand, Pierre; Lothon, Marie; Lenschow, Donald; Angevine, Wayne; Bange, Jens; Beare, Robert; Canut, Guylaine; Couvreux, Fleur; Delbarre, Hervé (2010)
      Conference report
      Open Access
      At the end of the afternoon, when the surface heat fluxes start to sharply decrease, the CBL turns from a convective well-mixed layer to an intermittently turbulent residual layer overlying a stably-stratified ...
    • The Boundary Layer Late Afternoon and Sunset Turbulence 2011 field experiment (BLT) 

      Lothon, Marie; Lohou, Fabienne; Durand, Pierre; Couvreux, Fleur; Hartogensis, Oskar; Legain, Dominique; Pardyjak, Erick; Pino González, David; Reuder, Joaquim; Vilà-Guerau de Arellano, Jordi (2012)
      Conference report
      Open Access
      Growth of the CBL over land in the middle of the day has been extensively observed and relatively successfully modeled. However the late afternoon transition (LAT), like the morning transition, is difficult to observe ...
    • Turbulence vertical structure of the boundary layer during the afternoon transition 

      Darbieu, Clara; Lohou, Fabienne; Lothon, Marie; Vilà Guerau de Arellano, Jordi; Couvreux, Fleur; Durand, Pierre; Pino González, David; Patton, Edward; Nilsson, Erik; Blay-Carreras, Estel; Gioli, Beniamino (2015-09-09)
      Article
      Open Access
      We investigate the decay of planetary boundary layer (PBL) turbulence in the afternoon, from the time the surface buoyancy flux starts to decrease until sunset. Dense observations of mean and turbulent parameters ...
