a second order closure model for calculating the turbulence fluxes in atmospheric boundary layer

turbulent fluxes in the atmospheric boundary layer are calculated using different models. one of the most popular and operational models in this groundwork is the second order turbulent model of mellor and yamada that has been widely used to simulate the planetary boundary layer (pbl). despite its popularity, it has been shown that this model has several weeknesses that affect its accuracy. the...

Shipboard Turbulence Measurements of the Marine Atmospheric Boundary Layer from Hires Experiment

In-situ instruments were installed on 12 m high masts at the bow (bow mast) and the crow nest (middle of the ship, ship mast). The principal sensors installed on each mast were: CSAT-3 sonic anemometer and a CS7500 LiCor LI7500 open path H20/CO2 analyzer/hygrometer. The bulk meteorology sensors were mean temperature and humidity sensors in aspirator and 2-D sonic anemometers for mean wind. Data...

Turbulence Structure of the Atmospheric Boundary Layer in Stable Conditions

Data from SABLES98 experimental campaign have been used in order to study the influence of stability (from weak to strong stratification) on the flux-profile relationships for momentum and heat: φm and φh. Standard instrumentation, 14 thermocouples and 3 sonic anemometers at three levels (5.8, 13.5 and 32 m) were available from 10 to 28 September 1998 and calculations are done in order to extra...

Turbulence Spectra and Dissipation Rates in a Wind Tunnel Model of the Atmospheric Convective Boundary Layer

A model of the atmospheric convective boundary layer (CBL) is realized in the thermally stratified wind tunnel of the Institute of Hydrology and Water Resources, University of Karlsruhe. Further experimental results from this model are presented. The wind tunnel with a test section 10 m long, 1.5 m wide, and 1.5 m high allows one to generate a quasi-stationary, horizontally evolving CBL, charac...

Planetary Boundary Layer Turbulence

In previous chapters boundary layers were evident as thin layers across which thermal, dynamic, and material properties of a free interior flow make a transition to their boundary values and/or boundary fluxes. In those cases the thinness of the boundary layer was typically a statement of the smallness of the relevant diffusivity; e.g., the depth h of the laminar Ekman boundary layer scales as ...
