“…Observations have shown the continuation of tropical sea breezes at night due to a lack of turning of the wind by the Coriolis force. The coupling of slope and sea-breeze circulations has also been observed (Atkinson 1981;Abbs 1986;Banta et al 1993;Mastrantonio et al 1994).…”

“…Very little research has been conducted on the effects of the geophysical variables on the return current or return-return current, over water subsidence, or convective initiation. Finally, the presence of a sea-breeze "precursor" noted in some observational studies (Banta et al 1993;Mastrantonio et al 1994) has not been numerically simulated to our knowledge.…”

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.

“…The position of this city very close to the Tyrrhenian coast (west side of italian peninsula) make the local atmospheric circulation complex because of the interactions between urban heat island (UHI) and sea breeze; observational works (Colacino and Dell'osso, 1978;Mastrantonio et al, 1994;Casadio et al, 1996) have established the importance of the sea breeze in the Rome area. A few previous numerical studies (Ferretti et al, 2003;Caballero and Lavagnini, 2002) show that simulation of local circulation in Rome area is challenging for the model.…”

Abstract. The urban forcing on thermodynamical conditions can greatly influence the local evolution of the atmospheric boundary layer. Heat stored in an urban environment can produce noteworthy mesoscale perturbations of the lower atmosphere. The new generation of high-resolution numerical weather prediction models (NWP) is nowadays often applied also to urban areas. An accurate representation of cities is key role because of the cities' influence on wind, temperature and water vapor content of the planetary boundary layer (PBL). The Advanced Weather Research and Forecasting model WRF (ARW) has been used to reproduce the circulation in the urban area of Rome. A sensitivity study is performed using different PBL and surface schemes. The significant role of the surface forcing in the PBL evolution has been investigated by comparing model results with observations coming from many instruments (lidar, sodar, sonic anemometer and surface stations). The impact of different urban canopy models (UCMs) on the forecast has also been investigated. One meteorological event will be presented, chosen as statistically relevant for the area of interest. The WRF-ARW model shows a tendency to overestimate the vertical transport of horizontal momentum from upper levels to low atmosphere if strong large-scale forcing occurs. This overestimation is partially corrected by a local PBL scheme coupled with an advanced UCM. Moreover, a general underestimation of vertical motions has been verified.

“…Note, that these studies do not have comparisons of synchronous urban and rural observations, so it is not clear if the profiles are relevant to the urban environment or to the whole region. The synchronous ABL characteristics in urban and rural environments were studied in Rome (Mastrantonio et al 1994).…”

We evaluate the statistical properties of low-level jets (LLJs) observed by means of a network of Doppler sodars in the Moscow region, Russia. Continuous long-term measurements of the echo-signal intensity and wind-velocity profiles were carried out in July 2005 and in 2008-2010 synchronously in the centre of Moscow and at a rural site. The summertime nocturnal LLJs have a very clear diurnal cycle and exhibit features predicted by the Blackadar mechanism. In contrast, the long-lasting wintertime jets do not have any clear diurnal variability. The urban environment strongly influences LLJs in both seasons: above the city LLJs are higher, weaker and observed more rarely than at the rural site. In very cold periods (air temperature below −8 • C) no LLJs were observed over the city, instead convection emerged in the urban boundary layer. The results are based on observations made in
