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} } @misc{DietzeMelladoStevensetal., author = {Dietze, Eckhard and Mellado, Juan Pedro and Stevens, Bjorn and Schmidt, Heiko}, title = {Study of low-order numerical effects in the two-dimensional cloud-top mixing layer}, series = {Theoretical Computational Fluid Dynamic}, journal = {Theoretical Computational Fluid Dynamic}, issn = {0935-4964}, doi = {doi:10.1007/s00162-012-0263-0}, language = {en} } @inproceedings{MelladoStevensSchmidt, author = {Mellado, Juan Pedro and Stevens, Bjorn and Schmidt, H.}, title = {Mean Shear Effects at the Cloud-Top Boundary}, 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{KumarStevensSchmidtetal., author = {Kumar, Suvarchal Kumar and Stevens, Bj{\"o}rn and Schmidt, Heiko and Mellado, Juan Pedro}, title = {Sensitivity of the ECHAM6 Single Column Model to Vertical Resolution and Implementation of the Level Set Method}, 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}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, 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{DietzeSchmidtMelladoetal., author = {Dietze, Eckhard and Schmidt, Heiko and Mellado, Juan Pedro and Stevens, Bjorn}, title = {LES vs. DNS simulation of a two-dimensional evaporatively driven cloud-top mixing layer}, series = {Conference on Multiple Scales in Fluid Dynamics and Meteorology}, booktitle = {Conference on Multiple Scales in Fluid Dynamics and Meteorology}, 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} }
