To develop wind farms projects both onshore and offshore in coastal area is challenging due to the effect of the coastal discontinuity of the surface characteristics. Especially the shape of the vertical wind profiles and then of the vertical profiles of the shape parameter c of the Weibull distribution are impacted by the atmospheric internal boundary layers developing from the coast along the wind direction. Here, we present first results from a unique database: one year of vertical wind profiles of wind speed and direction, monitoring programme at a coastal site located in the Calabria Region, 600m from the Tyrrhenian coastline, with a Lidar Doppler, ZephIr (ltd). We show cases of daily variation of vertical profiles of wind speed and directions local scale circulations versus the large scale conditions. Furthermore we present vertical profiles of the Weibull wind distribution c parameter and wind rose vertical variation.

Abstract
To develop wind farms projects both onshore and offshore in coastal area is challenging due to the effect of the coastal discontinuity of the surface characteristics. Especially the shape of the vertical wind profiles and then of the vertical profiles of the shape parameter c of the Weibull distribution are impacted by the atmospheric internal boundary layers developing from the coast along the wind direction. Here, we present first results from a unique database: one year of vertical wind profiles of wind speed and direction, monitoring programme at a coastal site located in the Calabria Region, 600m from the Tyrrhenian coastline, with a Lidar Doppler, ZephIr (ltd). We show cases of daily variation of vertical profiles of wind speed and directions local scale circulations versus the large scale conditions. Furthermore we present vertical profiles of the Weibull wind distribution c parameter and wind rose vertical variation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
