Journal ArticleDOI
The Parallelized Large-Eddy Simulation Model (PALM) version 4.0 for atmospheric and oceanic flows: model formulation, recent developments, and future perspectives
Björn Maronga,Micha Gryschka,Rieke Heinze,Fabian Hoffmann,Farah Kanani-Sühring,Marius Keck,Klaus Ketelsen,Marcus Oliver Letzel,Matthias Sühring,Siegfried Raasch +9 more
TL;DR: A detailed description of the current version of the Parallelized Large-Eddy Simulation Model (PALM) and its features, such as an embedded Lagrangian cloud model and the possibility to use Cartesian topography are given.
Journal ArticleDOI
A New Aerodynamic Parametrization for Real Urban Surfaces
TL;DR: In this paper, large-eddy simulations (LES) of fully developed turbulent flow within and above explicitly resolved buildings in Tokyo and Nagoya, Japan were conducted to provide a database of the horizontally-averaged turbulent statistics and surface drag corresponding to various urban morphologies.
Journal ArticleDOI
Modeling convection over arctic leads with LES and a non‐eddy‐resolving microscale model
Christof Lüpkes,Vladimir M. Gryanik,Vladimir M. Gryanik,B. Witha,Micha Gryschka,Siegfried Raasch,Tim Gollnik +6 more
TL;DR: In this article, the authors developed a turbulence closure for a microscale atmospheric model resolving the integrated effect of plumes emanated from leads, but not the individual convective eddies.
Journal ArticleDOI
Roll convection during a cold air outbreak: A large eddy simulation with stationary model domain
Micha Gryschka,Siegfried Raasch +1 more
TL;DR: In this article, a large eddy simulation (LES) of a cold air outbreak along with organized convection is presented, where the computational grid was chosen to be fine enough to explicitly resolve small scale unorganized turbulence, while the size of the model domain was large enough to include the evolution of large scale organized convections.
Formation of a Diurnal Thermocline in the Ocean Mixed Layer Simulated by LES
TL;DR: In this paper, the formation of a diurnal thermocline in the ocean mixed layer under a stabilizing buoyancy flux was simulated successfully by large-eddy simulation, reproducing various features consistent with observation.
