@phdthesis{fdi:010044897, title = {{R}egional atmospheric modelling of the stable water isotope cycle}, author = {{S}turm, {K}.}, editor = {}, language = {{ENG}}, abstract = {{C}limate change has recently become a major concerning among scientists and the general public. {A} better knowledge of past climates helps forecasting the future evolution of climate. {S}table water isotopes stand as an outstanding paleo-climate proxy. {P}hysical properties of heavy stable water isotopes ({H}218{O}, {HDO}) cause fractionation processes related to temperature and degree of distillation. {I}f the isotopic signal is correctly inverted, past climate change can be inferred from isotopic archives. {A}ndean ice-cores offer a unique records of tropical climate and its variability through time. {H}owever, the interpretation of the isotopic signal is difficult because of complex atmospheric dynamic over {S}outh {A}merica. {F}or this purpose, we developed a module handling the stable water isotope fractionation processes within the regional circulation model {REMO} and applied it to {S}outh {A}merica. {T}he manuscript outlines the major milestones of the present {P}h{D}. {W}e first introduce the research toic in the wider scope of climate change; the description of the stable water isotope enabled regional circulation model {REMO}iso; an initial validation of {REMO}iso over {E}urope; an investigation of the seasonal variations of precipitation, atmospheric circulation and isotopic signal over {S}outh {A}merica; and at last the recording of the south {A}merican monsoon system ({SAMS}) by stable water isotope diagnostics.}, keywords = {{ISOTOPE} ; {CIRCULATION} {ATMOSPHERIQUE} ; {CLIMAT} ; {MODELISATION} ; {PROPRIETE} {PHYSIQUE} ; {EAU} ; {PRECIPITATION} ; {VARIATION} {SAISONNIERE} ; {CHANGEMENT} {CLIMATIQUE} ; {MOUSSON} ; {MODEL} {REMO} ; {AMERIQUE} {DU} {SUD}}, address = {{S}aint {M}artin d'{H}{\`e}res ({FRA}) ; {M}ontpellier}, publisher = {{U}niv. {J}oseph {F}ourier ; {IRD}}, pages = {160 multigr.}, year = {2005}, URL = {https://www.documentation.ird.fr/hor/fdi:010044897}, }
