Des modelisations ont ete realisees sur les deux plus grands glaciers des Alpes francaises afin d'estimer leur evolution au cours du XXI e siecle. Pour un scenario climatique intermediaire avec reduction des emissions de gaz a effet de serre avant la fin du XXI e siecle (RCP 4.5), les simulations indiquent que le glacier d'Argentiere devrait disparaitre vers la fin du XXI e siecle et que la surface de la Mer de Glace pourrait diminuer de 80 %. Dans l'hypothese la plus pessimiste d'une croissance ininterrompue des emissions de gaz a effet de serre (RCP 8.5), la Mer de Glace pourrait disparaitre avant 2100 et le glacier d'Argentiere une vingtaine d'annees plus tot.

EnglishThis article presents the construction of a dataset describing French cities in terms of morphology, construction materials, and human behaviour related to building energy consumption. It describes an improvement of the urban climate model TEB to take into account the variety of building use and human behaviour at district scale. These developments are useful for modeling the urban climate and its interaction with building energy consumption and can help to better quantify the effect of climate change mitigation and adaptation measures in French cities. francaisCet article presente l'assemblage d'un jeu de donnees caracterisant les villes francaises en termes de morphologie, materiaux de construction et comportements energetiques.

EnglishLightning climatology in the Congo Basin is analyzed using data from the World Wide Lightning Location Network (WWLLN) from 2005 to 2013. A comparison with data from the optical space sensor LIS shows that the relative detection efficiency of the WWLLN increased from approximately 1.7% at the beginning of the period to 5.9% in 2013. These mean values over the entire area are low but related to all lightning flashes (intracloud and cloud-to-ground) and allow, however, obtaining a good representation of thunderstorm activity particularly strong in the study area. The average flash rate describes an annual cycle with high monthly proportions from October to March from 9 to 11%, and values at least 2 times lower from June to August. The meridian distribution of lightning shows a reinforcement between 5° S and 5° N with a maximum between 1° S and 2° S. The geographical distribution shows a very strong maximum in the East of the Democratic Republic of Congo (DRC), whatever the reference year and the period of the year. In 2013, the estimated annual lightning density taking into account DE and the number of thunderstorm days, calculated with a resolution of 0.1° x 0.1°, reached 218 flashes km-2 year-1 and 189 days, respectively. The maximum number of flashes per thunderstorm is in the same area, which means that thunderstorms are there, either more numerous, or more intense, or more stationary, or several of the three characteristics. This region is located west of the Virunga mountain range at an altitude that reaches 3 000 meters and plays a role in the initiation of thunderstorms during the year. In addition, the presence of the South African Easterly Jet (AEJ-S) at low altitude produces the instability necessary to the local development of Mesoscale Convective Systems (MCS) at the origin of this strong activity. These MCS can then propagate or regenerate to the west over a distance related to the influence of the phase of Kelvin waves propagating eastward. francaisLa climatologie des eclairs dans le bassin du Congo est analysee a l'aide des donnees du reseau World Wide Lightning Location Network (WWLLN) de 2005 a 2013. Une comparaison avec les donnees du capteur optique spatial LIS montre que l'efficacite de detection relative du reseau WWLLN passe d'environ 1,7 % au debut de la periode a 5,9 % en 2013. Ces valeurs moyennes sur l'ensemble de la zone sont faibles, mais concernent la totalite des eclairs (intranuage et nuage-sol) et permettent d'avoir une bonne representativite de l'activite orageuse particulierement forte dans la zone d'etude.
