TL;DR: In this paper, the authors present analyses of flow characteristics in the near-shore and offshore environment using data from the Danish wind monitoring network and show that wind speeds at or above a height of 40m are not significantly higher than that from land masts.

TL;DR: In this article, the urban impact on the sea breeze is studied by means of a mesoscale model with a detailed urban parameterization and four simulations are carried out on an idealised two-dimensional flat domain.
Abstract: The urban impact on the sea breeze is studied by means of a mesoscale model with a detailed urban parameterisation. Four simulations are carried out on an idealised two-dimensional flat domain. In the base case, half of the domain is characterised by sea and the other half by rural land. In the urban case, an urban area 10 km wide is added near the shoreline. Simulations are performed for a moist rural soil (weak sea breeze) and for a dry rural soil (strong sea breeze). Results are analysed in order to evaluate the impact of the city on the wind, temperature and turbulent kinetic energy fields. The dispersion of a passive tracer emitted near the coastline is, also, used in the comparison. Results show that the city accelerates the sea-breeze formation inthe morning (combinations of urban circulation and sea breeze), but it slows the sea-breeze front penetration. Moreover, the presence of the city enhances the recirculation processes and strongly modifies the pollutant dispersion. These effects are enhanced for a moist rural soil.

TL;DR: In this article, the horizontal distribution of ozone levels in the westcentral coastal plain of Taiwan was analyzed using 3-year data obtained from a network of air-pollution monitoring sites in the study area, while the vertical data came from two 2-day tethersonde experiments, measuring wind speed, direction, temperature and humidity, NO, NO2, NMHC and O3, conducted during August and November 1999.

TL;DR: In this article, the authors present atmospheric thermodynamic and aerosol data collected on 18 flights by the South African Aerocommander aircraft in the southern Arabian Gulf region and conclude that the bulk of the observed variability in particle vertical distribution appear to be controlled by mesoscale and microscale processes such as the sea/land breeze.
Abstract: [1] In August through September 2004 the United Arab Emirates Unified Aerosol Experiment (UAE2) was conducted in the southern Arabian Gulf region. We present atmospheric thermodynamic and aerosol data collected on 18 flights by the South African Aerocommander aircraft. In the first few kilometers, we observed high concentrations of both regional dust (from 100 to 300 μg m−3 in background, to over 1.5 mg m−3 in events) and ubiquitous sulfate based pollution from the Gulf's prevalent petroleum industry (10–100 μg m−3). Smoke and pollution from Europe and possibly Africa were found at levels between 1.5 and 5 km. Inland, classic deep over desert boundary layer characteristics were found. Over the Arabian Gulf, dust and pollution were most often either trapped below or sequestered above a strong stable boundary. However, there were cases where a well-distributed aerosol layer crossed the inversion uniformly. Data suggest that the observed vertical profiles can be explained by the rapid formation of stable marine boundary layers as air moves offshore. This can decouple aerosol layers from within the boundary layer to those aloft in regions of vertical wind shear. In the case of pollution, the ability of flaring plumes to penetrate the inversion may also in part determine layering. In coastal regions without vertical wind shear, uniform concentrations with height across the inversion are a result of internal boundary layer development. We conclude that the bulk of the observed variability in particle vertical distribution appear to be controlled by mesoscale and microscale processes, such as the sea/land breeze.
