The vadose zone is a zone sensitive to environmental changes and exerts a crucial control in ecosystem functioning and even more so in cold regions considering the rapid change in seasonally frozen ground under climate warming. While the way in… Read more

Accurate observations and simulations of soil moisture phasal forms are crucial in cold-region hydrological studies. In the seasonal frozen ground of Eastern Tibetan Plateau, water vapor, liquid and ice co-exist in the frost-susceptible silty-loam… Read more

Frozen ground covers a vast area of Earth surface and has its important ecohydrological implications for cold regions under changing climate. However, it is challenging to characterize the simultaneous transfer of mass and energy in frozen soils. Within the modeling… Read more

Accurate representing freeze-thaw (FT) process is of great importance in cold region hydrology and climate studies. With the STEMMUS-FT model (Simultaneous Transfer of Energy, Mass and Momentum in Unsaturated Soil), we investigated the coupled water and heat transfer in the… Read more

A simulation analysis of the advective effect on evaporation using a two-phase heat and mass flow model The concept of enhanced vapor transfer in unsaturated soils has been questioned for its reliance on soil temperature gradient, which leads to consideration of… Read more

Numerical analysis of air‐water‐heat flow in unsaturated soil: Is it necessary to consider airflow in land surface models? From a subsurface physical point of view, this paper discusses the necessity of considering the two‐phase heat and mass transfer process in land surface… Read more

Case Study 1: The effect of different evapotranspiration methods on portraying soil water dynamics and ET partitioning in a semi-arid environment in Northwest China Different methods for assessing evapotranspiration (ET) can significantly affect the performance of land surface models… Read more
