Abstract

The turbulent static pressure spectrum Epp(kx) as a function of longitudinal wavenumber kx in the roughness sublayer of forested canopies is of interest to a plethora of problems such as pressure pumping from snow or forest floor. Long term static pressure measurements above a sub-arctic forested canopy during the winter and spring were collected and analyzed for three snow cover conditions: trees and ground covered with snow, trees are snow free but the ground is covered with snow, and snow free cover. In all three cases, it is shown that Epp(kx) obeys the attached eddy hypothesis at low wavenumbers (1/δ
