Statistical Scaling of Turbulent Surface Pressure in the Atmospheric Boundary Layer
… surface pressure simultaneous with the boundary-layer meteorology over a wide range of atmospheric conditions. The velocity data were then used to fit the turbulence model parameters, and predictions of the surface pressure spectra were made. These predictions were compared with the …

Vegetation feedback on the boundary layer climate of South Africa
… land surface and vegetation to the atmospheric boundary layer over southern Africa are investigated. Satellite derived rainfall and vegetation data and model evaporative fluxes for the period 1981-2000 are used to reveal spatial and temporal inter-relationships via Principal Components Analysis. …

Tracer-Independent Approaches to Stratosphere-Troposphere Exchange and Tropospheric Air Mass Composition
… to either where it was last in the planetary boundary layer (PBL), or where it was last in contact with the tropopause. The utility of these air-mass fractions in isolating the climate change signature on transport alone is demonstrated for the climate of a dynamical-core circulation model and …

The influence of longwave cloud-top cooling on marine stratocumulus cloud transitions
… structure within the stratocumulus-topped boundary layer in the Southeast Pacific is simulated using near-LES model framework and sounding data from the Variability of American Monsoon Systems (VAMOS) Ocean–Cloud–Atmosphere–Land Study Regional Experiment (VOCALS-REx) as the initial …

A numerical study of surface air temperature response to vertical mixing and momentum extraction by wind farms and the impacts of wind farms on mesoscale boundaries
… and TKE coefficients along with the wind turbine layer static stability determine the temperature change impact. During night, statically stable conditions result in strong warming signals while during the day near-neutral conditions result in insignificant impacts. The magnitude of the signal is …

Modeling nighttime chemistry with WRF/chem: sensitivity to vertical resolution and boundary layer parameterization
… phase and aerosol phase species in the nocturnal boundary layer. Resolving these profiles adequately is a prerequisite for a good representation of nighttime chemistry and poses an important modeling challenge. In this work we explore the sensitivity of the model results for N2O5 and aerosol …
