C21E:
Frozen Soil, Its Change, and the Responses and Feedbacks of the Frozen Soil Change in Atmosphere, Hydrology, and Ecosystem I


Session ID#: 11035

Session Description:
Frozen soil is an important component of cryosphere. Atmosphere, frozen soil, water and ecosystem together form a dynamic system that is filled with responses and feedbacks. Distinctive features in atmosphere, hydrology and ecosystems are associated with the frozen soil. For example, at different thawing and freezing stages, soil surface sensible and latent heat fluxes assume dominant roles differently. Permafrost soil limits the interaction between soil surface and deep groundwater due to the hydraulic impedance. In high altitudes, the wetland ecosystem is associated with the permafrost soil. With warming climate, frozen soil degradation has been reported in the high latitudes and altitudes. Components of the dynamic system are expected to alter, and so do the responses and feedbacks among the components. In this session, we welcome studies that focus on the frozen soil modeling and observation, the mechanisms of frozen soil change, and the responses and feedbacks in the dynamic system.
