Idealised numerical simulations of aerodynamical roughness lenght effects on sea breeze characteristics

A two-dimensional hydrostatic meso-gamma-scale model is used to study possible effects of a step change in roughness on the daytime sea breeze (SB). Idealised numerical simulations with the length of aerodynamical roughness (z0) ranging from 0.05m to 1.0 m and by an increase of 0.05 m in all land surface grid points were made. Two z0 effects could be pointed out: an increase in the mixing process and a reduction in the wind speeds in the surface layer. An increase of both heights and magnitudes of the SB circulation, caused by a vertical extension of the turbulent field, followed by a faster inland penetration of the SB. The second effect resulting from a successive increase in z0 values was a retardation of the sea breeze front near the ground, visible in its slope. This effect allowed the already faster inland penetration of the marine air high above the land.
