Full textClimate variability influences marine primary productivity and marine species distribution over all timescales, from seasonal to interannual variability and glacial-interglacial cycles. The links between climate and marine ecosystems are still sparsely known so that the predictions of futur changes are difficult. Moreover, because paleoclimate recorders extracted from marine archives are often linked to the functionning of the ecosystem, this lack of knowledge limits our ability to reconstruct past climate variability.This thesis work aims at improving our knowledge of these links between climate and marine ecosystems : we have looked into marine productivity changes during the last glacial-interglacial cycle, but we also examined the "end-to-end" ecosystem response to inter-annual to decadal variability in a pre-industrial climate. This work uses a climate model (IPSL-CM), a bio-geochemical model (PISCES) and a model of high trophic levels (APECOSM).First, we show that the link between Indian summer monsoon intensity and marine primary productivity in the Arabian Sea is indirect. Indeed, it appears necessary to consider the monsoon pattern, such as the Findlater Jet position, which drives the Ekman dynamics in the region, as well as its intensity to understand the productivity changes.Second, we study the marine productivity changes off the Congo river mouth and their links with the river runoff and the African atmospheric dynamics. This work shows that the relationship between monsoon intensity and trade winds intensity, often used to reconstruct past changes, is not always verified. Depending on the climate, thermal or dynamical effects are more or less prominent drivers of the simulated changes in precipitation and winds. Productivity off the Congo river mouth, which is mainly located in the subsurface, seems more affected by the ocean and atmosphere dynamics than by the river supply in nutrients.Third, we study the inter-annual variability effects over past productivity changes and over the climatic signal potentially recorded in the biological climate proxies.Finally, the last part of the thesis focuses on high trophic levels marine organisms response to climate variability at different frequencies. This study shows that marine organisms response to environmental changes varies with the organism' size and habitat

Full textLandslides have been often studied, but rarely on the valley scale. The set of parameters controlling the evolution of slope can be observed with this scale, and in Particular those responsible for the triggering of landslides. The study led in the High Tinée Valley (Argentera‐Mercantour) brings new evidences to understand slopes’ destabilisations: 10Be dating of polished glacial surfaces: Three stage of glacial recession have been measured around 15 ka, 11 ka and 8‐9 ka. These ages are similar to data acquired previously in Northern and Central parts of Alps. It suggests that climate fluctuations are homogeneous on the Alps scale. Periods of glacier retreat are chronologically concordant with gravity events measured in the Alps. A strong increase of river incision from 4 ka to reach incision rate greater than 1 cm. An‐1 around 1,2 – 0,7 ka has been measured. This period is concordant with dating acquired on the basal sliding of La Clapière landslide between 1,8 and 0,6 ka. Field investigations associated with numerical models allowed observing of the subertical and parallel to the valley fracture propagation, from the slope toe to the top of the landslides. These new data have resulted in a model of the mountain slope destabilization involving several factors: (i) Glacial incision and effects from ice melt involve a destabilisation of the valley and the initiation of landslides. (ii) River incision participates to the slope destabilisation. (iii) Mechanical damage of the slope accelerates the weathering and the gravity process

Full textAt vineyard scale, climate variability can be significant in magnitude and play a key role in vine and wine characteristics. Adaptation of viticulture to climate change requires knowledge about future fine-scale climate evolution. This study aims to integrate local scale in future climate projections, coupling dynamic and statistical modelling. A first step consisted in producing temperature maps at 1 km resolution using WRF in a vineyard area (Marlborough, New-Zealand) and evaluating model uncertainties. It revealed that dynamical models do not represent well local climate variations. Using a high density temperature data logger network, the second part is dedicated to developing a non-linear statistical model to map temperature at very fine scale in famous sub-appellations of the Bordeaux vineyard area (Saint-Émilion). Following, a method, coupling dynamical and statistical modelling, is proposed to integrate local scale in climate change projections. This thesis highlights that using simultaneously statistical and dynamical models can be an approach to reduce model uncertainties

Full textThe Euro-Mediterranean region is subject to high aerosol loads of various origins and with high spatial and temporal variability. The climate of this region will be impacted by their direct effect on radiation but also by their semi-direct and indirect effects on clouds and atmospheric dynamics. This thesis work, which is part of the Med-CORDEX and ChArMEx research programmes, will address through regional climate modelling the question of the direct radiative effect of the various aerosols over the historical period, their evolution between the period 1971-2000 and the period 2021-2050 as well as the sensitivity of the future climate of this region to these aerosols. In order to take into account as fully as possible anthropogenic aerosols in the ALADIN-Climat regional climate model, used throughout this thesis work, a new simplified aerosol module to represent nitrate and ammonium particles has been implemented in its interactive aerosol scheme TACTIC. A set of simulations, taking into account or not nitrate and ammonium particles, were carried out over the period 1979-2016. The results showed the significant impact of these atmospheric particles on the Euro-Mediterranean climate with a contribution of 40% to the total AOD (at 550 nm) and a direct radiative forcing higher than that of sulphate and organic carbon particles from 2005. Over a longer period of time and using different scenarios, results show a decrease of total AOD of 35% over Europe between 1971-2000 and 2021-2050. This is mainly due to the decrease of the sulphate aerosols AOD, partly offset by the increase of nitrates. Nitrate particles will also have the highest total AOD contribution over Europe, of 45%, during the future period. This evolution of the various aerosols will impact their direct radiative forcing, with a significant decrease in that exerted by sulphate particles and an increase in that of nitrate and ammonium aerosols. These changes, which are robust under the different scenarios, explain on an annual average about 6% of the expected global warming over Europe between the two periods, mainly due to aerosols-radiation interactions but also to a change in cloud albedo (first indirect effect) and atmospheric dynamics over this region

Full textAnthropogenic aerosols may have a noticeable impact on the life cycle of boundary layer clouds, via their effects on radiation and precipitation efficiency. It is however difficult to document such impacts from observations. The interactions between aerosol particles and the dynamics of boundary layer cloud systems (typically marine stratocumulus) have therefore been explored with high resolution numerical models (LES), that now include detailed parameterizations of turbulence, radiative transfer and microphysics. In this study, the focus is on the coupling between aerosol impacts on cloud microphysics and the diurnal cycle of stratocumulus clouds. LES simulations of a 36 hours cycle are performed with aerosol concentrations typical of pristine and polluted air masses, successively. Although the simulations start from the same initial state, they rapidly diverge. The increased concentration of cloud condensation nuclei yields to an increased droplet concentration, a reduction of the droplet sizes and the inhibition of the droplet sedimentation and precipitation formation. The liquid water content at cloud top hence increases and the cloud top entrainment is strengthened. Moreover, the absorption of solar radiation at cloud base is no longer balanced by the droplet and drizzle evaporation, and the decoupling of the cloud layer is reinforced. Overall, the polluted cloud layer is better coupled during the night and more decoupled during the day than its pristine counterpart. Measurable signatures of these impacts are identified to help at designing observational studies of aerosol impacts on the dynamics on boundary layer clouds
