[Numerical simulation of interaction between forest ecosystem and atmosphere boundary layer]

Area of Science:

• Atmospheric Science
• Ecology
• Micrometeorology

Context:

• Understanding the complex interactions between forest ecosystems and the atmospheric boundary layer is crucial for regional climate modeling.
• Existing models often lack the detailed representation of canopy processes and their influence on atmospheric dynamics.

Purpose:

• To develop and validate a numerical model simulating the diurnal variations of heat balance and microclimatic variables within forest ecosystems.
• To investigate the temporal and spatial distributions of key atmospheric parameters influenced by forest canopies.

Summary:

• A numerical model was constructed based on atmospheric boundary layer and plant canopy micrometeorology principles.
• The model simulates diurnal variations in heat balance, canopy and air temperatures, ground surface temperature, and profiles of potential temperature, wind speed, specific humidity, and turbulence exchange coefficients.
• Simulation results demonstrated the model's capability in analyzing land surface-atmosphere interactions.

Impact:

• Provides a robust framework for studying land surface processes and their impact on the atmospheric boundary layer across diverse surface types.
• Establishes a foundation for enhancing the coupling of climate models with biosphere processes.
• Contributes to a better understanding of regional climate effects influenced by forest ecosystems.
