Abstract
- Foram realizadas simulacoes climaticas a partir de 2 experimentos de sensibilidade numerica conduzidos com um modelo acoplado de complexidade intermediaria, LOVECLIM , estendendo-se para um periodo de 300 anos. Sendo que, neste experimento foi realizada a reducao em 50% da topografia geral do hemisferio norte, um com modelo acoplado (oceano-atmosfera) e outro desacoplado (somente atmosfera). Nos resultados obtidos, foram observadas alteracoes no padrao de clima global e local, em especial a regiao da Asia, relacionadas com aumento de temperatura do ar a superficie e intensidade do vento. Maiores alteracoes foram observados em regioes continentais no hemisferio norte. Isto mostra o maior impacto local causado pela forcante topografica com o a reducao da pela metade da topografia boreal. Palavras-chave : Topografia, Mudancas Climaticas, Modelos Climaticos, Forcante Climatica Modelling the Impact of Topography on Global Climate Boreal ABSTRACT Simulations were conducted from two numerical sensitivity experiments conducted with a coupled model with intermediate complexity, LOVECLIM, extending for a period of 300 years. Since this experiment was carried out 50% reduction in the general topography of the northern hemisphere, with a coupled model (ocean-atmosphere) and the other uncoupled (atmosphere only). Their results have been observed changes in the pattern of global and local climate, particularly in Asia, linked to increase of air temperature and wind intensity. The biggest impacts were observed in continental regions in the north hemisphere. This shows the greater local impact caused by topographic forcing Keywords : Topography, Climate Change, Climate Models, Topographic Forcing
