Abstract

In order to validate the isotopic models of the general circulation of the atmosphere ECHAM5-wiso and ECHAM6-wiso, modeling in nudging mode was made. These model data were compared with experimental data on the isotope composition (δHDO and δH218O) of precipitation for stations in the foothills of Altai mountains (52.596° N, 85.25° E) created and maintained by the Institute for Water and Environmental Problems SB RAS.
