Momentum Transfer and Turbulent Kinetic Energy Budgets within a Dense Model Canopy
Second-order closure models for the canopy sublayer (CSL) employ a set of closure schemes developed for ‘free-air’ flow equations and then add extra terms to account for canopy related processes. Much of the current research thrust in CSL closure has focused on these canopy modifications. Instead of offering new closure formulations here, we propose a new mixing length model that accounts for b...
متن کاملModeling CO2 and water vapor turbulent flux distributions within a forest canopy
One-dimensional multilayer biosphere-atmosphere models (e.g., CANVEG) describe ecosystem carbon dioxide (CO2) and water vapor (H2O) fluxes well when cold temperatures or the hydrologic state of the ecosystem do not induce stomatal closure. To investigate the CANVEG model framework under such conditions, CO2, H2O, and sensible heat fluxes were measured with eddy-covariance methods together with ...
متن کاملMissing Peroxy Radical Sources within a Rural Forest Canopy
REFEREE 1 The manuscript “Missing peroxy radical sources within a rural forest canopy” by Wolfe et al 2014 presents a solid and unique set of measurements within a Ponderosa Pine forest. The main focus of this paper is the observation and analysis of peroxy radicals. Therefore various gas chemical measurements were utilized to run a box model and compare the modeled diel cycle to the observatio...
متن کاملReply to comments on ”Simulating ozone dry deposition at a boreal forest with a multi-layer canopy deposition model”
“In SOSAA, the horizontal wind velocity (u and v), temperature (T ), specific humidity (qv), turbulent kinetic energy (TKE) and the specific dissipation of TKE (ω) are computed every time step (10 s) by prognostic equations. In order to represent the local to synoptic scale effects, u, v, T and qv near and within the canopy are nudged to local measurement data at SMEAR II station with a nudging...
متن کاملTurbulent kinetic energy in normal and myopathic left ventricles.
PURPOSE To assess turbulent kinetic energy (TKE) within the left ventricle (LV) of healthy subjects using novel 4D flow magnetic resonance imaging (MRI) methods and to compare TKE values to those from a limited group of patients with a spectrum of dilated cardiomyopathy (DCM). MATERIALS AND METHODS 4D flow and morphological MRI data were acquired in 11 healthy subjects and 9 patients with dif...
