Numerical Simulation of the Interaction between Forest Ecological System and Atmospheric Boundary Layer

Abstract

Based on the basic principles of the micrometeorology of atmospheric boundary layers and vegetation canopy, a numerical model of the interaction between forest ecosystems and atmospheric boundary layers was developed. The model is used to simulate the diurnal variations of heat balance in forest ecosystems, canopy temperatures, ground surface temperatures, as well as the profiles of temporal and spatial distributions of potential temperatures, wind speeds, specific humidity, and turbulence exchange coefficients. Our study indicates that themodel can be applied to study the interaction between land surface processes and atmospheric boundary layers over various underlying surfaces and their regional climate effects. This paper will establish a solid foundation to investigations on the coupling of climate models and the biosphere.
