“…In addition, due to the positioning of this point at a 305 m altitude, a possible turn with the height of the predominant direction generated by the thermally induced circulation cells should be considered. This could explain a possible contribution to the predominance of W-WSW in the afternoon (sea breeze) at D-15 m, while, at the other tower site, the sea breeze could be attributed, in general, to the directions of SW, SSW and S. Thus, it can be said that the bimodal behavior It is worth mentioning that the wind roses from all tower sites (Figures 4-9) show records of wind directions between NNE and E. In addition to the contribution of the local factors mentioned above (i.e., channeling processes and breeze circulations), such registers can also be associated with an eventual influence from the SASA, which typically induces first quadrant winds in the state of Rio de Janeiro [82,83].…”

Ilha Grande Bay is located in Angra dos Reis, Rio de Janeiro State, Brazil. The area is characterized by different land cover, complex topography and proximity to the Atlantic Ocean. These aspects make it susceptible to thermally and dynamically induced atmospheric circulations such as those associated with valley/mountain and land/sea breeze systems, among others. The Almirante Álvaro Alberto Nuclear Complex (CNAAA) is located in this region, with a total of two nuclear power plants (NPPs) in operation in the Brazilian territory, Angra I and Angra II. Therefore, knowledge of local atmospheric circulation has become a matter of national and international security. Considering the importance of the meteorological security tool as a support for licensing, installation, routine operation and nuclear accident mitigation, the main aim of this study is the development of combined strategies of environmental statistical modeling in the analysis of thermally and dynamically driven atmospheric circulations over mountainous and coastal environments. We identified and hierarchized the influence of the thermally and mechanically driven forcing on the wind regime and stability conditions in the coastal atmospheric boundary layer over the complex topography region. A meteorological network of ground-based instruments was used along with physiographic information for the observational characterization of the atmospheric patterns in the spatial and time–frequency domain. The predominant wind directions and intensity are attributed to the combined action of multiscale weather systems, notably, the valley/mountain and continent/ocean breeze circulations, the forced channeling due to valley axis orientation, the influence of the synoptic scale systems and atmospheric thermal tide. The observational investigation of the combined influence of terrain effects and meteorological systems aimed to understand the local atmospheric circulation serves as support for safety protocols of the NPPs, contemplating operation and environmental management. The importance of the study for the adequacy and skill evaluation of computational modeling systems for atmospheric dispersion of pollutants such as radionuclide and conventional contaminants can be also highlighted, in order that such systems are used as tools for environmental planning and managing nuclear operations, particularly those located in regions over mountainous and coastal environments with a heterogeneous atmospheric boundary layer.

“…The topographic data collected from the United States Geological Survey (USGS) have been set to a resolution of 10 arcminutes for grid 1; 5 arcminutes for grid 2; 2 arcminutes for grid 3 and 30 arc seconds for grid 4. The parameterizations were chosen as suggested by Dragaud et al (2018) and are summarized in Table 1.…”

Estimulada por acordos ambientais globais, a busca por alternativas de geração de energia renovável vem aumentando em todo o mundo. Embora o Brasil tenha um grande território com diferentes recursos naturais, sua matriz energética é altamente dependente da fonte hidráulica. Este artigo avalia a capacidade de uso da energia eólica no topo de morros e montanhas, considerando o potencial eólico nesses locais e, assim, estimulando seu desenvolvimento no país. O modelo Weather Research and Forecasting (WRF) foi aplicado para identificar os recursos eólicos e definir os melhores locais para a instalação de aerogeradores na área da Cooperativa Agrícola de Vieira, localizada em Teresópolis, região montanhosa do estado do Rio de Janeiro, Brasil. Como pequenos aerogeradores operam próximos ao solo e, portanto, têm custos mais baixos do que os grandes, a produção estimada de eletricidade de um aerogerador nacional, de pequeno porte, foi comparada com o consumo real de uma lavoura de referência local. Apesar da fraca representação topográfica, os resultados mostram que a região possui recurso eólico suficiente para fornecer eletricidade aos agricultores ao longo do período estudado do ano, reduzindo seus custos de produção. Portanto, é possível melhorar o uso de energia eólica no Brasil em zonas montanhosas e, no processo, diversificar a matriz energética do país.

“…Land-sea interactions observed in coastal areas are quite complex and feed the appearance of phenomena falling within the scientific areas of climatology and meteorology at different spatio-temporal scales [1]. Air observation has always been an essential precondition for monitoring and predicting weather and studying the effects of climatic and meteorological phenomena [2].…”

Coastal environment, an area where abrupt changes occur between land and sea, significantly affects the quality of life of a high portion of the Earth’s population. Therefore, the wide range of phenomena observed in coastal areas need to be assessed reliably regarding both data sets and methods applied. In particular, the study of coastal atmospheric transport phenomena which affect a variety of activities in coastal areas, using modeling techniques, demand accurate estimations of a range of meteorological and climatological variables related to the planetary boundary layer. However, the accuracy of such estimations is not obvious. Geoinformatics is able to fill this gap and provide the framework for the design, processing and implementation of accurate geo-databases. This paper aims to highlight the role of geoinformatics in the context of coastal meteorology and climatology. More precisely, it aims to reveal the effect on the performance of a Mesoscale Meteorological Model when a new scheme regarding the input surface parameters is developed using satellite data and application of Geographical Information Systems. The development of the proposed scheme is described and evaluated using the coastal Metropolitan Area of Athens, Greece as a case study. The results indicate a general improvement in the model performance based on the statistical evaluations of three meteorological parameters (temperature, wind speed and wind direction) using four appropriate indicators. The best performance was observed for temperature, then for wind direction and finally for wind speed. The necessity of the proposed new scheme is further discussed.
