The Plane Area of Daily Dynamics of Microclimate Gradient Concepts, Methods and Application Results

Abstract

Parameter the plane area of daily dynamics of microclimate gradients is the plane area surrounded by the curve of daily dynamic of microclimate gradients with the thermal equilibrium lines. This parameter shows the thermal interaction of forest ecosystems with the environment. This interaction is the process of thermal diffusion through the boundary plane, in the horizontal direction. Mathematical analysis and modeling for the determination of function and plane area of the daily dynamics of the micro-climate gradient include the stages with the output of other micro-climate parameters that are commonly used before. Variations of ecosystem conditions and adjacent environments have different magnitudes in gradient dynamics. The results of the study show that this parameter has a more stable magnitude than the other microclimate parameters. Changes or variations in the quantity of this parameter can also detect the influence of weather, the existence of gap or hole, detect patches in the structure of the forest. Current development shows that this parameter can also characterize the vertical interaction between air and water and air with soil.

Temperature Gradient Daily Dynamics Area and Time Zoning for Local Analysis of Air-Water Interaction

“…The stages of analysis and modeling of the TGDDA parameters are described in detail in previous articles (Medellu and Tulandi, 2018;Medellu 2019Medellu , 2020 as follows: 1) Measurement of air temperature at 5 to 7 position along the transect, 2) Tabulate the data into a matrix format based on position (line: x) and time (column: t), which produces temperature data on the basis of position and time: T (x, t) 3) Modeling of the temporal function T (t). The temporal function is a sinusoidal function, so its modeling uses the Fourier function modeling mechanism.…”
