Distribution spatiale et variabilité des régimes pluviométriques en Catalogne (Espagne et France): originalité du littoral

1999

Ponencia presentada en: I Congreso de la Asociación Española de Climatología “La climatología española en los albores del siglo XXI”, celebrado en Barcelona del 1 al 3 de diciembre de 1999. [ES]En la línea litoral de Cataluña domina un régimen pluviométrico mediterráneo marítimo, con su máximo otoñal y su mínimo estival. Pero las costas orientadas al Sureste se diferencian de las orientadas al Este, donde la topografía favorece matices locales. El régimen marítimo sufre una fuerte variabilidad interanual sobre el litoral. El régimen medio no se observa más que algunos años. A veces, incluso, pueden presentarse lluvias intensas en primavera y verano. [EN]In Catalonia, the Mediterranean and m…

Dynamique spatio-temporelle d’un événement extrême froid : impact de la circulation atmosphérique sur les basses températures en Bourgogne viticole.

2020

During April 2019 France experienced several frost events that caused extensive damage to almost all of its winegrowing regions. In Bourgogne-Franche-Comté the frost effects were very punctual and spatially diffused, the greatest damage being observed in the early bud breaking winegrowing sub-regions of Saône-et-Loire and the south of the Côte de Beaune. This study focuses on the multi-scalar analysis of the spring frost event underwent during the night between the 4th and 5th of April on a vineyard plot located in the Hautes Côtes de Beaune appellation. The analysis highlights the impact of local parameters (topography, surface discontinuity, etc.) on the spatio-temporal structuring of tem…

Étude des températures simulées avec Méso-NH : sensibilité à l’artificialisation des sols à Grenoble et Lyon.

2022

International audience; La modélisation atmosphérique à très fine échelle permet d’analyser la dynamique de l’îlot dechaleur urbain en contexte de topographie complexe. Deux simulations (Urbaine et Non-Urbaine) mettenten évidence les effets associés à l'urbanisation. La taille des agglomérations, dans le cas de Lyon etGrenoble, n'influence pas la différence de température entre les deux simulations. Les conditions destabilité influencent fortement ces différences. L'ICU peut être intensifié par l'affaiblissement du vent oul’effet de piégeage et/ou le développement d’une couche d’inversion.

Rainfall and Sea-Breeze Circulation over South-Western France

1997

South-western France (Aquitaine region) has an oceanic temperate climate but some climatic peculiarities (irregular patterns in isohyets) are observed along a narrow coastal belt. The spatial distribution of winter and summer precipitation shows a ‘rainy strip’ located around 20 to 40 km inland. Three features allow an explanation of this distribution: synoptic flow, sea-breeze and heterogeneous land roughness (presence of the Foret des Landes). To take into account the impact of these features, numerical simulations are examined using a three-dimensional mesoscale model. The occurrence of the forest increases the possibility of precipitation during irregular patterns in isohyets. © 1997 by…

Variabilité climatique printanière et phénologie végétale en Auxois : exemple d'Alise-Sainte-Reine (Côte d'Or).

2018

Un suivi photographique est effectué depuis 2011 sur le site viticole d'Alise-Sainte-Reine, dans l'Auxois en Bourgogne du Nord (département de la Côte-d'Or), afin de mettre en évidence des indicateurs permettant d'expliquer la variabilité interannuelle des stades phénologiques de certaines espèces végétales par l'analyse de la variabilité climatique et de la fréquence, succession et durée des types de circulation atmosphérique et de temps. Les photos prises au début du mois de mai montrent une différence sensible entre d'une part les années 2011 et 2018, et d'autre part les années 2016 et 2017.

Heat in Normandy, types of atmospheric circulation and climate change (1970 - 2019)

2020

Heat in Normandy, synoptic circulation patterns and climate change (1970-2019). This article focuses on the role and the evolution of the different kinds of synoptic circulation patterns in the occurrence of hot days in Normandy. Heat is here, very dependent on the presence of action centres over central Europe as well as, air flow coming from NE and E. Contemporary climate change expresses itself by a rise in thermal efficiency of all synoptic circulation patterns (more heat for the same flow). Lastly, the north of Cotentin stands out by being a real “cool island” during summer because of its peninsula position which imposes on any air mass, regardless of its origin, a cooling from its bot…

Spatial distribution of the precipitation in Dobruja (Romania/Black Sea)

2000

An original dataset for the Dobruja, a low plateau region of southeastern Romania, is used to perform a statistical study of the spatial distribution of rainfall at annual and seasonal time-scales. A principal component analysis (PCA) is carried out to identify the precipitation regimes. The high eigenvalue of PC1 attests of the prevailing temperate-continental regime, with a relatively dry winter opposed to a late spring and early summer rainfall maximum. PC2 shows the specific pattern of the coast, with a small secondary maximum in November. In spite of the relatively flat topography, annual rainfall is characterized by a strong gradient between the coast and the interior. Particularly lo…
