D3.3 Dynamical downscaling of climate & atmospheric impacts

This deliverable D3.3 “Dynamical downscaling of climate & atmospheric impacts” provides a description of high resolution modeling approach to downscale both meteorological and wind information for the four HYPERION pilot sites. The downscaled information will be utilized by analysis techniques developed in HYPERION project to assess the impact of weather on the deterioration, decay and structural stress on building materials and structures. The downscaling methodology for wind impacts is founded on high-resolution Large-eddy Simulation (LES) analyses, which provide spatially and temporally detailed information on the turbulent wind conditions within the pilot cities. This is achived by employing a nested domain approach, which enable the solution of both large scale atmospheric boundary layer turbulence and micro scale urban turbulence simultaneously. The wind information is provided in a scalable form which allows its employment in analysis covering different meteorological conditions.
