“…5). Observational studies have corroborated the horizontally non-uniform structure and oscillatory propagation speed of the sea-breeze front simulated by models run at high resolution (Yoshikado 1990;Wakimoto and Atkins 1994;Wood et al 1999;Stephan et al 1999;Puygrenier et al 2005). A number of air pollution dispersion models have simulated the "translocation" or significant vertical advection of pollutants by narrow frontal plumes, the effect of the convective internal boundary layer on pollutant fumigation, interactions between urbaninduced circulations and sea breezes, and the effects of turbulence and multilayer stratification on recirculation (Lemonsu et al 2006;Thompson et al 2007).…”

Numerical studies of sea and lake breezes are reviewed. The modelled dependence of sea-breeze and lake-breeze characteristics on the land surface sensible heat flux, ambient geostrophic wind, atmospheric stability and moisture, water body dimensions, terrain height and slope, Coriolis parameter, surface roughness length, and shoreline curvature is discussed. Consensus results on the influence of these geophysical variables on sea and lake breezes are synthesized as well as current gaps in our understanding. A brief history of numerical modelling, an overview of recent high-resolution simulations, and suggestions for future research related to sea and lake breezes are also presented. The results of this survey are intended to be a resource for numerical modelling, coastal air quality, and wind power studies.

“…Such a transition from land breeze to local morning breeze, evolving afterwards to a regional breeze in the afternoon, was already observed and modelled (Puygrenier, 2005) during the ESCOMPTE field campaign near Marseille, in southern France. The MFLK experiment showed the same characteristics.…”

A B S T R A C T The THAUMEX measurement campaign, carried out during the summer of 2011 in Thau, a coastal lagoon in southern France, focused on episodes of marine breezes. During the campaign, three intensive observation periods (IOPs) were conducted and a large amount of data were collected. Subsequently, standalone modelling using the FLake lake model was used, first to assess the surface temperature and the surface energy balance, and second to determine the energy budget of the water column at the measurement site. Surface fluxes were validated against in situ measurements, and it was determined that heat exchanges are dominated by evaporation. We also demonstrated that the model was sensitive to the light extinction coefficient at Thau, due to its shallowness and clarity nature. A heat balance was calculated, and the inclusion of a radiative temperature has improved it, especially by reducing the nocturnal evaporation. The FLake lake model was then evaluated in three-dimensional numerical simulations performed with the Meso-NH mesoscale model, in order to assess the changing structure of the boundary layer above the lagoon during the IOPs more accurately. We highlighted the first time ever when Meso-NH and FLake were coupled and proved the ability of the coupled system to forecast a complex phenomenon but also the importance of the use of the FLake model was pointed out. We demonstrated the impact of the lagoon and more precisely the Lido, a sandy strip of land between the lagoon and the Mediterranean Sea, on the vertical distribution of turbulent kinetic energy, evidence of the turbulence induced by the breeze. This study showed the complementarities between standalone and coupled simulations.

“…In particular, diurnal wind variations upon coastal plains, where most of the global population resides, are an important factor in controlling problems related to pollution and heat-island effects. The land−sea breeze prevails in areas of coastal plains (e.g., see Miller et al 2003 for a review), controlling the transport of pollutants (e.g., Kurita et al 1990;Puygrenier et al 2005). …”
