This paper examines the effects of soil moisture initialization in a coupled air quality–meteorological model on temperature profiles, wind speeds, and pollutant concentrations. Three simulations, each with different initial soil moisture fields, were run. In the baseline simulation, predicted temperatures, wind speeds, and gas/aerosol pollutant concentrations accurately matched observations. I...

Land surface models (LSM) are widely used as scientific and operational tools to simulate mass and energy fluxes within the soil vegetation atmosphere continuum for numerous applications in meteorology, hydrology or for geobiochemistry studies. A reliable parameterization of these models is important to improve the simulation skills. 5 Soil moisture is a key variable, linking the water and ener...

Thin-layer moisture adsorption tests were conducted by exposing com kernels to different air relative humidities (RH of 75, 80, and 90%) and temperatures (25, 30, 35, and 40°C). A two-dimensional finite element model was developed to simulate moisture diffusion into a com kernel during adsorption. The finite element model satisfactorily predicted experimental moisture ratio of corn samples and ...

[1] Simulations from eight climate models and two greenhouse gas emission scenarios are used to investigate changes in the hydrologic budget of the Great Lakes region of North America and the links to large-scale hemispheric/ global changes. The ensemble average simulations indicate that increased net moisture (increased P-E) for the Great Lakes area is associated with a general increase in pol...

uncertainty analysis is a useful tool to evaluate soil water simulations in order to get more information about the models output. these information provide more confidence for decision making processes. in this study, swap model is applied for soil water balance simulations in two fields which are planted by wheat and maize in an arid region. first the amount of uncertainty is estimated and co...

Modelling solute transport in an unsaturated zone (vadose) depends very much on the simulation of soil moisture and moisture fluxes, which are strongly influenced by precipitation, evapotranspiration, surface runoff and land-surface properties. To provide good approximations of soil moisture and moisture fluxes, a model capable of simulating land-surface processes is required. In this study, a ...

The UC Berkeley Comfort Model is a helpful simulation tool for the assessment of thermal comfort in non-uniform environments. A major element of the model is the implementation of a clothing node, which considers both heat and moisture capacitance of clothing. Heat capacity of the clothing has been demonstrated to be important when considering transient effects. Moisture capacitance is importan...

In arid regions, water resources are a key forcing factor in ecosystem circulation, and soil moisture is the critical link that constrains plant and animal life on the soil surface and underground. Simulation of soil moisture in arid ecosystems is inherently difficult due to high variability. We assessed the applicability of the process-oriented CoupModel for forecasting of soil water relations...

Seven composite models of meta-aramid fibers with different moisture contents were studied using molecular dynamics simulation. The effects of moisture on the thermal stability and mechanical properties of the fibers and their mechanisms were analyzed, considering characteristics such as hydrogen bonding, free volume, mean square displacement, and mechanical parameters. The simulation results s...
