Research Abstract

Transfer processes of heat and water (vapor) were observed on tundra, plain taiga, mountain taiga, Mongolian grass field, and Tibetan Plateau in eastern Eurasian Continent. Continuous measurement of one-dimensional heat and water vapor fluxes revealed clear seasonal variation due to latitudinal radiation forcing, Monsoon activity, and plant phonological activity. Observations of atmospheric boundary layer using radiosonde and airborne were carried out to derive aggregation processes of heat and water vapor fluxes from local (patch) to regional scales. Water transfer mechanisms in active layer of permafrost and in the atmospheric boundary layer were also derived using stable isotopic ratio of H_2O in Siberian and Tibetan permafrost regions. Regional hydrological modeling was done in the Lena river basin. This model included schemes representing one-dimensional heat and water vapor transfer, runoff process, and water transfer in river channel network.
