  abstract = {{T}his paper provides a new representation of the effect of altitude on precipitation that represents spatial and temporal variability in precipitation in the {E}verest region. {E}xclusive observation data are used to infer a piecewise linear function for the relation between altitude and precipitation and significant seasonal variations are highlighted. {A}n original ensemble approach is applied to provide non-deterministic water budgets for middle and high-mountain catchments. {P}hysical processes at the soil-atmosphere interface are represented through the {I}nteractions {S}oil-{B}iosphere-{A}tmosphere ({ISBA}) surface scheme. {U}ncertainties associated with the model parametrization are limited by the integration of in situ measurements of soils and vegetation properties. {U}ncertainties associated with the representation of the orographic effect are shown to account for up to 16% of annual total precipitation. {A}nnual evapotranspiration is shown to represent 26% +/- 1% of annual total precipitation for the mid-altitude catchment and 34% +/- 3% for the high-altitude catchment. {S}nowfall contribution is shown to be neglectable for the mid-altitude catchment, and it represents up to 44% +/- 8% of total precipitation for the highaltitude catchment. {T}hese simulations on the local scale enhance current knowledge of the spatial variability in hydroclimatic processes in high-and mid-altitude mountain environments.},
