Resistance Laws and Prediction Equations for the Depth of the Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: A further discussion of the resistance laws for barotropic planetary boundary layers is presented. Concrete expressions are obtained for universal functions A(?0), B(?0) C(?0)of Rossby number similarity theory for the Ekman ...
Similarity Theory for the Planetary Boundary Layer of Time-Dependent Height
Publisher: American Meteorological Society
Abstract: The conventional similarity theory for the planetary boundary layer is amended to contain the actual boundary-layer height scale h rather than the neutral rotation height scale u*/|f|.
Scale Relations for Global Air-Sea Interaction
Publisher: American Meteorological Society
Abstract: The role of the oceans in the formation of the earth's climate is discussed. A simple model for global air-sea interaction is proposed which takes into account the latitudinal variation of the planet's radiation budget, ...
NOTES AND CORRESPONDECEScaling Reasoning and Field Data on the Sea Surface Roughness Lengths for Scalars
Publisher: American Meteorological Society
Abstract: The heat and mass transfer over the sea is considered in terms of the sea surface roughness lengths for scalars, z0T for potential temperature ?, and z0q for specific humidity q, or alternatively, in terms of the roughness-layer ...
The Effect of Foam on Waves and the Aerodynamic Roughness of the Water Surface at High Winds
Publisher: American Meteorological Society
Abstract: AbstractThis paper models the impact of the presence of foam on the short-wave component of surface waves and momentum exchange in the atmospheric boundary layer at high winds. First, physical experiments were carried out ...
The “Bag Breakup” Spume Droplet Generation Mechanism at High Winds. Part II: Contribution to Momentum and Enthalpy Transfer
Publisher: American Meteorological Society
Abstract: AbstractIn Part I of this study, we used high-speed video to identify ?bag breakup? fragmentation as the dominant mechanism by which spume droplets are generated at gale-force and hurricane wind speeds. We also constructed ...
Third-Order Transport and Nonlocal Turbulence Closures for Convective Boundary Layers
Publisher: American Meteorological Society
Abstract: The turbulence closure problem for convective boundary layers is considered with the chief aim to advance the understanding and modeling of nonlocal transport due to large-scale semiorganized structures. The key role here ...
