Correlation Analysis of Underlying-Surface Temperature,Insolation,and Wind Velocity in the Atmospheric Surface Layer

摘要

A correlation analysis of fluctuations in underlying-surface temperature is proposed.This analysis allows one,from the total random temperature field,to separate its portion most closely related to one or another parameter affecting the temperature.A spectral analysis of experimental data is used to obtain the transfer functions that relate variations in land surface temperature to fluctuations in insolation and horizontal wind velocity,as well as to wind-velocity fluctuations initiated by insolation.The transfer functions make it possible to obtain the spectra of individual surface-temperature components and to calculate the contribution of each of the components to the total variance of surface-temperature fluctuations.An analysis of the transfer functions allows one to determine the system's parameters and the interaction mechanism.
