International audience; The acceleration of climate-induced changes in high arctic environments is evident and lead to a wide range ofprocesses (e.g. glacier retreat, landslide activity). Recent studies (Bernard et al. 2014) provide evidence that, thestability of the talus covered slopes is reducing and thus landslides are occurring more frequently on the slopessurrounding the Austre Lovénbreen glacier.The Austre Lovénbreen glacier basin is a relatively small arctic glacier basin located at 79◦N, Ny-Ålesund(Svalbard) and geologically is part of the Kongsvegen Group, which is composed of the Nielsenfjellet, Steenfjelletand the Bogegga Formation. This study focusses on the quantitative and sp…

Climats tropicaux d'aujourd'hui à demain : variabilité et changements

2008

Present and future tropical climates : their climate variability and their climate changes The oriffttality of tropical climates is re-examined under the light of climate variability and climate change, both present and future . The interannual variability of rainfall is on average larger in the tropics than in the extra-tropics, but it is also spatially more contrasted. Human communities have often responded to this constraint through efficient coping strategies. The regions showing the most variable climate do not necessarily have lower population densities, an indication that in the long run variability is not decisive. However, the recent demographic growth of these regions is often low…

Types de configurations pluviométriques sur le bassin méditerranéen, forçages atmosphériques et évènements intenses (1979-2013).

2015

Sixrecurrent and redundant daily rainfall patterns have been extracted over the Mediterranean area from 1979 to 2013: five areassociated to regionals rainfall excess (South-West Mediterranean, Mid-North Mediterranean, East Mediterranean, WestMediterranean and north-west Mediterranean) and one to generalized deficit. Each rainfall pattern is associated with atypical barometric spatial configuration leading to local wind bringing moisture to the coast leading to specific local rainfallsurplus. Rainfall patterns also explain a large part of the spatial characteristics and the probability of occurrence of intenseevents. For example, more than 20% of days of “West-Mediterranean” rainfall pattern…
