The National Center for Atmospheric Research will host a workshop in Boulder, Colorado, September 26-28, 2006 sponsored by the Geophysical Turbulence Program (GTP). The workshop will bring together researchers interested in the roughness sublayer; the layer of flow immediately above (or below) a boundary surface (air-land or air-water interface) containing stationary and moving roughness elements, such as stones, vegetation (trees), buildings, wind turbines, or water waves. The approaches considered are numerical and laboratory modeling, observations, and theory.
Scientific Background and Rationale:
The roughness sublayer normally extends from the interface up
to about two to several times the height of the roughness
elements. Within the roughness sublayer the flow is
three-dimensional and site-dependent since it is dynamically
influenced by the length scales and density/porosity of the
individual roughness elements. Turbulence properties and scalar
transport (including deposition) may vary with the surface type
and texture, e.g., bluff obstacles in cities versus the fibrous
"fine-grained" elements of vegetation.
The workshop will feature a series of invited talks, interspersed with discussion sessions, and short contributed oral presentations. The invited talks will focus on recent observational, numerical modeling, and laboratory simulation results to better understand turbulence structure and transport in roughness sublayers. The discussions will focus on fundamental issues related to the roughness sublayer and how we deal with the roughness sublayer in a variety of applications. A summary paper is planned to be submitted to a scientific publication.
Voluntary abstract submission:
Anyone who wishes to give a brief oral presentation is required to provide a one-page (maximum) abstract by 1 June 2006. Submission of an abstract does not guarantee that you will be speaking, since there may not be enough time to include all who wish to speak. Please email your abstract (in pdf format) to Liz Rothney rothney "at" ucar .dot. edu
Extended abstract for invited speakers:
All invited speakers should email a 2-page extended abstract (in pdf) to Liz Rothney rothney "at" ucar .dot. edu by 15 August 2006.
