The goal is to understand the assumptions intrinsic to this simplified but commonly employed approach for the study of two-layer buoyancy reversing systems like the cloud-top mixing layer. Emphasis is placed on molecular transport phenomena. In particular, a formulation is proposed that recovers the actual nondiffusive liquid-phase continuum as a limiting case of differential diffusion. High-order numerical schemes suitable for direct numerical simulations in the compressible and Boussinesq limits are described, and simulations are presented to validate the incompressible approach. As expected, the Boussinesq approximation provides an accurate and efficient description of the flow on the scales (of the order of meters) that are considered.}, language = {en} } @misc{MelladoStevensSchmidtetal., author = {Mellado, Juan Pedro and Stevens, Bjorn and Schmidt, Heiko and Peters, Norbert}, title = {Buoyancy reversal in cloud-top mixing layers}, series = {Quarterly Journal of the Royal Meteorological Society}, volume = {135}, journal = {Quarterly Journal of the Royal Meteorological Society}, number = {641}, issn = {1477-870X}, doi = {10.1002/qj.417}, pages = {963 -- 978}, language = {en} } @inproceedings{MelladoSchmidtStevensetal., author = {Mellado, Juan Pedro and Schmidt, Heiko and Stevens, Bjorn and Peters, Norbert}, title = {Analysis of the cloud top mixing layer using DNS}, language = {en} } @inproceedings{MelladoStevensSchmidtetal., author = {Mellado, Juan Pedro and Stevens, Bjorn and Schmidt, Heiko and Peters, Norbert}, title = {The evaporatively driven cloud-top mixing layer}, series = {63rd Annual Meeting of the APS Division of Fluid Dynamics}, booktitle = {63rd Annual Meeting of the APS Division of Fluid Dynamics}, language = {en} } @inproceedings{DietzeStevensMelladoetal., author = {Dietze, Eckhard and Stevens, Bjorn and Mellado, Juan Pedro and Peters, Norbert and Schmidt, Heiko}, title = {Level set methods for meteorological multi scale problems}, series = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, booktitle = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, language = {en} } @inproceedings{MelladoStevensSchmidtetal., author = {Mellado, Juan Pedro and Stevens, Bjorn and Schmidt, Heiko and Peters, Norbert}, title = {Buoyancy reversal in the cloud-top mixing layer}, series = {4th IMS Turbulence Workshop, Workshop, 23-25 March 2009,}, booktitle = {4th IMS Turbulence Workshop, Workshop, 23-25 March 2009,}, language = {en} } @inproceedings{MelladoSchmidtStevensetal., author = {Mellado, Juan Pedro and Schmidt, Heiko and Stevens, Bjorn and Peters, Norbert}, title = {DNS of the turbulent cloud-top mixing layer}, series = {Advances in turbulence XII, proceedings of the 12th EUROMECH European Turbulence Conference, September 7 - 10, 2009, Marburg, Germany}, booktitle = {Advances in turbulence XII, proceedings of the 12th EUROMECH European Turbulence Conference, September 7 - 10, 2009, Marburg, Germany}, publisher = {Springer}, address = {Berlin [u.a.]}, isbn = {978-3-642-03084-0}, pages = {401 -- 404}, language = {en} } @inproceedings{MelladoStevensSchmidtetal., author = {Mellado, Juan Pedro and Stevens, Bjorn and Schmidt, Heiko and Peters, Norbert}, title = {Investigation of the Cloud-Top Interface Using Direct Numerical Simulation}, series = {Oberwolfach reports, Mathematical Theory and Modelling in Atmosphere-Ocean Science}, volume = {7}, booktitle = {Oberwolfach reports, Mathematical Theory and Modelling in Atmosphere-Ocean Science}, number = {3}, doi = {10.4171/OWR/2010/34}, pages = {2061 -- 2062}, language = {en} } @inproceedings{SchmidtMelladoPetersetal., author = {Schmidt, Heiko and Mellado, Juan Pedro and Peters, Norbert and Stevens, Bjorn}, title = {Towards a modular superparameterization for Stratocumulus clouds considering unsteady entrainment}, series = {4th PAN-GCSS Meeting on Advances in modeling and observing clouds and convection, 2-6 June 2008, Toulouse, France}, booktitle = {4th PAN-GCSS Meeting on Advances in modeling and observing clouds and convection, 2-6 June 2008, Toulouse, France}, language = {en} } @inproceedings{SchmidtMelladoPetersetal., author = {Schmidt, Heiko and Mellado, Juan Pedro and Peters, Norbert and Stevens, Bjorn}, title = {Towards modular front tracking for Stratocumulus clouds considering unsteady entrainment processes}, series = {European Geosciences Union General Assembly 2008, Vienna, Austria, 13 - 18 April 2008}, booktitle = {European Geosciences Union General Assembly 2008, Vienna, Austria, 13 - 18 April 2008}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{MelladoStevensSchmidtetal., author = {Mellado, Juan Pedro and Stevens, Bjorn and Schmidt, Heiko and Peters, Norbert}, title = {New results about the cloud-top entrainment instability}, series = {Conference on Multiple Scales in Fluid Dynamics and Meteorology}, booktitle = {Conference on Multiple Scales in Fluid Dynamics and Meteorology}, pages = {31}, language = {en} }
