Resumo: Guincho is known as the windiest beach of Portugal, ideal for nautical activities, such as windsurfing and kitesurfing. The main goals of this study are to explore the wind characteristics in Guincho and to compare the synoptic forecasts accessible to the public with actually occurring weather conditions. We used meteorological data, synoptical information, forecasts and field observations during the summers of 2009 and 2010. A sample of 124 days with good conditions for windsurfing were selected and classified into different groups. Within each group, the wind measured (and indirectly observed) in Guincho was compared to the results of the Global Forecast System (GFS). This analysis led to a useful classification allowing interpretation of GFS surface wind forecasts available to surfers at Guincho. We conclude that global weather models do not accurately forecast the wind, particularly due to model resolution and parameterisations, which do not detail local phenomena.

O caso da praia do Guincho. A praia do Guincho, conhecida como a mais ventosa de Portugal, é ideal para a prática de windsurf e kitesurf. O principal objectivo deste estudo é explorar as características do vento no Guincho, comparando-as com as previsões me‑ teorológicas, acessíveis ao público. Usaram-se dados meteorológicos, informações si‑ nópticas, previsões e observações de terreno feitas nos verões de 2009 e 2010. Foi utili‑ zada uma amostra de 124 dias, com boas condições para a prática de windsurf, a qual foi classificada em diferentes grupos. Dentro de cada grupo foi medida a intensidade do vento (também observada indirectamente), tendo sido depois comparados com os resul‑ tados do modelo americano de previsão (Global Forecast System – GFS). Esta análise conduziu a uma classificação, que é útil para interpretar as previsões do GFS acessíveis a quem pratica surf no Guincho. Chegou-se à conclusão de que os modelos de previsão não são suficientemente rigorosos para dar conta das condições de vento, porque a resolução e o tipo de parametrização dos modelos não atende às características particulares dos locais.Le Vent, une ressource pour les activités nautiques récréatives: Le cas de guincho. La plage de Guincho, qui est connue pour être la plus ventée du Portugal, est un lieu idéal pour la pratique de la planche à voile et du kitesurf. L’objectif de cette étude est d’établir les caractéristiques du vent à Guincho et leur lien avec la situation synoptique. Elle est basée sur des données météorologiques (information synoptique, pré‑ visions et observations sur le terrain), obtenues pendant les étés 2009 et 2010. On a analysé un échantillon de 124 jours ayant des conditions adéquates pour la pratique de la planche à voile. Ils ont été analysés et classés par similarité en différents groupes. Pour chacun d’eux, la vitesse et la direction du vent ont été comparées aux données de prévision du modèle américain Global Forecast System (GFS), ce qui a permis d’établir une classification utile pour interpréter ladite prévision, facilement accessible aux pratiquants d’activités nautiques à Guincho. On en conclut que les modèles globaux de prévision sont insuffisamment précis et rigoureux, parce que leur résolution et leur paramétrisation ne détaillent pas assez les caractéristiques locales.Universidade de Lisboa, Centro de Estudos GeográficosRepositório da Universidade de LisboaVermeersch, WenzelAlcoforado, Maria Joao2017-09-13T14:52:42Z20132013-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10451/28949eng0430-502710.18055/Finis3134info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-07-14T15:19:05ZPortal AgregadorONG
