Energetics and similarity theory in the wave-affected atmospheric boundary layer
… boundary layer (WBL). Using Monin-Obukhov (MO) Similarity Theory, we analyzed the fluxes and energy balance under different atmospheric stability conditions. Through a comparison of non-dimensional data with the universal functions given in Edson and Fairall (1998), we determined that the Edson …

Application of similarity theory to forecasting the mixed-layer depth of the ocean
… greatly affects sonar ranges. In this paper, similarity theory is applied to the problem of forecasting the depth of the mixed layer during the warm season, assuming the controlling processes are secular, non-advective , and non-divergent. The resulting forecast method consists mainly of two …

An experimental study of turbulent vortex rings using particle image velocimetry
… Particle Image Velocimetry. In the late 1980s’ a similarity theory of turbulent vortex rings was proposed and tested primarily using a twochannel tracking Laser Doppler Velocimeter. However, due to the limitations of the experimental technique the tests were inconclusive and important assumptions …

Mechanisms of turbulent mixing in the Continental Shelf bottom boundary layer
… the results are consistent with Monin-Obukhov similarity theory, while in the outer part of the boundary layer other scales including the height of the boundary layer are important for setting the turbulent length scale.

Roughness length variability over heterogeneous surfaces
Monin-Obukhov similarity theory and the empirical formulae of Businger et al. (1971) and Dyer (1974) are used to calculate roughness lengths and surfacelayer heat fluxes from multilevel observations of wind, temperature, and humidity measured at three locations in the Weather Information Network …

Using Reanalysis Data For The Prediction Of Seasonal Wind Turbine Power Losses Due To Icing
… methods, the method using boundary-layer similarity theory to determine temperature and relative humidity shows the most accuracy in predicting icing losses closest to observed losses at the Petersburg location with an average absolute difference of 2.13 % ± 1.29 %. This is a …

Turbulence in Natural Environments
… Heisenberg's eddy viscosity, Monin Obukhov Similarity Theory (MOST) etc. under a common framework. In the case of a more complex scenario such as presence of a vegetation canopy with edges and gaps, the question that is addressed is in what detail the turbulence is needed to be resolved in …

Land-atmosphere Exchange and Air Quality during Stable Atmospheric Boundary Layer Events
… stability functions based on the Monin-Obukhov similarity theory is responsible for the CH discrepancies. Numerical sensitivity experiments show that there is no one WRF configuration that performs best for all meteorology variables (temperature, wind speed, surface turbulent fluxes) and under …

Study of VOCs Transport and Storage in Porous Media and Assemblies
… of this dissertation are: (1) validate the similarity hypothesis between the transport of water vapor and VOCs in porous materials, and help build a database of VOC transport and storage properties with the assistance of the similarity hypothesis; (2) investigate the effect of relative …

Optimizing Lidar Scanning Strategies for Wind Energy Turbulence Measurements
… and tested on data from the field campaigns. Similarity theory was used to estimate the approximate ratio of the horizontal variance components to the vertical variance as a function of stability, which can then be used to calculate new values of the horizontal variance components, if an …

Surface-Atmosphere coupling over the central Arctic Ocean
… too large and the application of Monin-Obukhov similarity theory under the observed conditions. The measurements show that the boundary layer was almost always less than 200 m deep; this means that the constant flux layer was always less than 20 m deep and often extended to only a few metres …
