TL;DR: In this article, satellite observations of surface winds and rainfall were used to show the offshore copropagation of land breeze and diurnal rainfall signals for 300-400 km from the east coast of India into the Bay of Bengal.
Abstract: Satellite observations of infrared brightness temperature and rainfall have shown offshore propagation of diurnal rainfall signals in some coastal areas of the tropics, suggesting that diurnal rainfall is coupled to land-sea breeze circulations. Here we utilize satellite observations of surface winds and rainfall to show the offshore copropagation of land breeze and diurnal rainfall signals for 300–400 km from the east coast of India into the Bay of Bengal. The wind observations are from the 2003 Quick Scatterometer (QuikSCAT)-SeaWinds “tandem mission” and from 17 years of the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI); the rainfall observations are from the TRMM 3B42 product and from TMI. The surface wind convergence maximum leads the rainfall maximum by 1–2 h in the western part of the bay, implying that the land breeze forces the diurnal cycle of rainfall. The phase speed of the offshore propagation is approximately 18 m s−1, consistent with a deep hydrostatic gravity wave forced by diurnal heating over India. Comparisons with a cloud system-resolving atmospheric model and the ERA-Interim reanalysis indicate that the models realistically simulate the surface land breeze but greatly underestimate the amplitude of the rainfall diurnal cycle. The satellite observations presented in this study therefore provide a benchmark for model representation of this important atmosphere-ocean-land surface interaction.

TL;DR: In this paper, an analysis is made of the diurnal variation of the winds measured at Hilo Airport by conventional soundings during the summer of 1965. Butler et al. focused on the strong land-sea breeze regime which dominates local winds over the eastern slopes of the Island of Hawaii.
Abstract: Attention is called to the strong land-sea breeze regime which dominates local winds over the eastern slopes of the Island of Hawaii. An analysis is made of the diurnal variation of the winds measured at Hilo Airport by conventional soundings during the summer of 1965. The diurnal wind oscillation has a maximum range of over 6 m sec ?1 at the surface and extends to an altitude of over 3 km. An example of the trajectory of a radar-tracked, constant volume balloon is analyzed to illustrate the combined effect of sea breeze and barrier deflection flow on the local winds measured over the slopes.

TL;DR: In this article, the authors measured radon and air pollution at Uchio (Okayama City, Okayama Prefecture, Japan) 12 km north from the coast of the Inland Sea of Japan.
Abstract: Concentrations of radon 222Rn andair pollutants, meteorological parametersnear the surface and vertical profiles of meteorological elements were measured atUchio (Okayama City, Okayama Prefecture, Japan) 12 km north from the coast ofthe Inland Sea of Japan. In the nighttime, the 222Rn concentration increased in the case of weak winds, but did not increase as much in the case of moderate or strong winds, as had been expected. In the daytime, the 222Rn concentrationheld at a slightly higher than average level for the period from sunrise to about 1100 JST. It is considered that this phenomenon is due to a period of morning calm, that is, a transition period from land breeze to sea breeze.NO, which is sensitive to traffic volume,brought information concerning advection.Oxidant concentrations,which reflect the availability of sunlight,acted in the reverse manner to 222Rnconcentrations. Thus, a set of 222Rn and air pollutants could provide useful information regarding the local conditions of the atmospheric boundary layer.

TL;DR: In this article, the cumulative effects from wind turbine encounters have weak effects on the relative attitude towards more onshore and offshore wind power development and the results suggest that increasing onshore wind energy development does not make people favor offshore wind turbine development to a higher extent.
Abstract: An increasing number of studies suggest that the cumulative impacts of wind turbine encounters might have a negative impact on the acceptance of onshore wind power development. In many countries offshore wind resources are seen as the new wind energy resource, though the offshore cost of energy is markedly higher compared to onshore. In the present paper it is tested if the cumulative effect of wind turbines makes people favour offshore wind turbine development to onshore development. The results suggest that the cumulative effects from wind turbine encounters have weak effects on the relative attitude towards more onshore and offshore wind power development. This suggests that increasing onshore wind power development does not make people favour offshore wind power development to a higher extent.

TL;DR: In this paper, results on photochemical pollutants monitoring obtained in the field campaign CZCM-2001 were used as a database in photochemical trajectory model using the explicit mechanism Master Chemical Mechanism version 3 (MCM v3) aiming to simulate the formation of photochemical pollutant in air masses during the sea breeze circulation at Portugal West Coast.
