  abstract = {{T}he low-frequency evolution of {I}ndian rainfall mean-state and associated interannual-to-decadal variability is discussed for the last 6000 years from a multi-configuration ensemble of fully coupled global transient simulations. {T}his period is marked by a shift of {I}ndian {S}ummer {M}onsoon {R}ainfall ({ISMR}) distribution towards drier conditions, including extremes, and a contraction of the rainy season. {T}he drying is larger in simulations with higher horizontal resolution of the atmosphere and revised land surface hydrology. {V}egetation-climate interactions and the way runoff is routed to ocean modulate the timing of the monsoon onset but have negligible effects on the evolution of seasonal rainfall amounts in our modeling framework in which carbon cycling is always active. {T}his drying trend is accompanied by changes in {ISMR} interannual-to-decadal variability decreasing over north and south {I}ndia but increasing over central {I}ndia (20 degrees-25 degrees {N}). {T}he {ISMR} interannual-to-decadal variability is decomposed into six physically consistent regimes using a clustering technique to further characterize its changes and associated teleconnections. {F}rom 6 to 3.8 kyrbp, the century-to-century modulations in the frequency of occurrence associated to the regimes are asynchronous between the simulations. {O}rbitally-driven trends can only be detected for two regimes over the whole 6-0 kyrbpperiod. {T}hese two regimes reflect increased influence of {ENSO} on both {ISMR} and {I}ndian {O}cean {D}ipole as the inter-hemispheric energy gradient weakens. {S}evere long-term droughts are also shown to be a combination of long-term drying and internally generated low-frequency modulations of the interannual-to-decadal variability.},
