'''High-resolution LES studies of the turbulent structure of the lower atmospheric boundary layer over heterogeneous terrain and implications for the interpretation of scintillometer data'''\\ Responsible: Björn Maronga\\ Project type: [[http://www.dfg.de|DFG]] research project\\ Duration: 01/07/2010-31/05/2012\\ \\ A detailed description will follow soon...\\ \\ == Movies == ||||='''First sequence: Structure parameters in the counvective boundary layer (2010)''' =|| {{{#!td style="vertical-align:top; border: 0px solid" {{{#!html }}} }}} {{{#!td style="vertical-align:top; border: 0px solid"" '''Description:''' This DVR visualization shows the turbulent structure parameter C,,T,,^2^ in the surface layer of a convectively driven boundary layer. Dark colors match to high values up to 0.01, whereas white colors represent lower values down to 0.001. All values which are out of range are set to transparent. Shown is the last half an hour of the simulation. The movies shows, that C,,T,,^2^ is high near the surface, decreasing with height. High values, in comparison with their horizontal environment can be observed in regions where warm air rises upward (plumes). These regions organize in hexagonal cells, which can also be seen in this sequence.\\ ||||='''Model Setup''' =|| ||Total domain size (x|y|z):||1280m x 1280m x 1080m|| ||Grid spacing (x|y|z):||5m x 5m x 5m|| ||Number of grid points (x|y|z):||256 x 256 x 256|| ||Simulated time:||1.5h|| ||CPU-time:||1.5h|| ||Number of CPUs:||64|| ||Machine/ processor type:||SGI Altix ICE at HLRN / Intel Xeon Gainestown|| ||Visualization software:||VAPOR|| \\ }}}
