Vertical Velocities and Available Potential Energy Generated by Landscape Variability—Theory
Publisher: American Meteorological Society
Abstract: It is shown that landscape variability decreases the temperature in the surface layer when, through mesoscale flow, cool air intrudes over warm patches, lifting warm air and weakening the static stability of the upper part ...
Heat and Momentum Fluxes Induced by Thermal Inhomogeneities with and without Large-Scale Flow
Publisher: American Meteorological Society
Abstract: The authors Present an analytical evaluation of the vertical heat and momentum fluxes associated with mesoscale flow generated by periodic and isolated thermal inhomogeneities within the convective boundary layer (CBL). ...
The Detection of Mixed Layer Depth and Entrainment Zone Thickness from Lidar Backscatter Profiles
Publisher: American Meteorological Society
Abstract: A new method is presented for the extraction of mixed layer depth and entrainment zone thickness from lidar, backscatter ratio profiles. The method is based on fitting a four parameter, idealized profile to observed profiles. ...
Mesoscale Nonhydrostatic and Hydrostatic Pressure Gradient Forces—Theory
Publisher: American Meteorological Society
Abstract: A theory is presented for the evaluation of the different terms of the pressure gradient force, when mesoscale flow is driven by a sensible heat source in the planetary boundary layer (PBL), or by an elevated confined heat ...
