The Diurnal Behavior of Evaporative Fraction in the Soil–Vegetation–Atmospheric Boundary Layer Continuum
Publisher: American Meteorological Society
Abstract: he components of the land surface energy balance respond to periodic incoming radiation forcing with different amplitude and phase characteristics. Evaporative fraction (EF), the ratio of latent heat to available energy ...
Role of Surface Friction on Shallow Nonprecipitating Convection
Publisher: American Meteorological Society
Abstract: AbstractThe role of surface friction on shallow nonprecipitating convection is investigated using a series of large-eddy simulations with varying surface friction velocity and with a cloud identification algorithm. As ...
Coherent Structures in the Boundary and Cloud Layers: Role of Updrafts, Subsiding Shells, and Environmental Subsidence
Publisher: American Meteorological Society
Abstract: oherent structures, such as updrafts, downdrafts/shells, and environmental subsidence in the boundary and cloud layers of shallow convection, are investigated using a new classification method. Using large-eddy simulation ...
Coherent Structures in Large-Eddy Simulations of a Nonprecipitating Stratocumulus-Topped Boundary Layer
Publisher: American Meteorological Society
Abstract: AbstractThe properties of coherent convective structures are analyzed in a nonprecipitating marine nocturnal stratocumulus-topped boundary layer (STBL) with a series of high-resolution large-eddy simulations (LESs). A new ...
A Closer Look at Boundary Layer Inversion in Large-Eddy Simulations and Bulk Models: Buoyancy-Driven Case
Publisher: American Meteorological Society
Abstract: he inversion layer (IL) of a clear-sky, buoyancy-driven convective boundary layer is investigated using large-eddy simulations covering a wide range of convective Richardson numbers. A new model of the IL is suggested and ...
Resolving Contrasting Regional Rainfall Responses to El Niño over Tropical Africa
Publisher: American Meteorological Society
Abstract: he evolution of El Niño can be separated into two phases?namely, growth and mature?depending on whether the regional sea surface temperature has adjusted to the tropospheric warming in the remote tropics (tropical regions ...
Neural Network–Based Sensitivity Analysis of Summertime Convection over the Continental United States
Publisher: American Meteorological Society
Abstract: lthough land?atmosphere coupling is thought to play a role in shaping the mean climate and its variability, it remains difficult to quantify precisely. The present study aims to isolate relationships between early morning ...
Radiative–Convective Equilibrium over a Land Surface
Publisher: American Meteorological Society
Abstract: adiative?convective equilibrium (RCE) describes an idealized state of the atmosphere in which the vertical temperature profile is determined by a balance between radiative and convective fluxes. While RCE has been applied ...
Impact of Soil Moisture–Atmosphere Interactions on Surface Temperature Distribution
Publisher: American Meteorological Society
Abstract: nderstanding how different physical processes can shape the probability distribution function (PDF) of surface temperature, in particular the tails of the distribution, is essential for the attribution and projection of ...
Data Length Requirements for Observational Estimates of Land–Atmosphere Coupling Strength
Publisher: American Meteorological Society
Abstract: ultiple metrics have been developed in recent years to characterize the strength of land?atmosphere coupling in regional and global climate models. Evaluation of these metrics against observations has proven challenging ...
