Special Issue Information

Dear Colleagues,

The atmospheric boundary layer, the lowermost layer of the atmosphere, is host to a plethora of physical processes that strongly affect life on Earth and the planetary energy balance. The overarching goal of the Special Issue on “Turbulent Transport in Atmospheric Boundary Layers” is to address emerging problems in the understanding and modelling of the multi-physics character of the boundary layer. We aim to understand the links and interactions between classical turbulence dynamics and other processes, such as radiation, cloud microphysics, and land surface interactions.

Since the late 1960s, the boundary layer has been a hallmark for the study of classical turbulence dynamics, including stratification effects. Many observational campaigns and, more recently, modelling studies contributed valuable insights into the boundary layer by mostly focusing on idealized configurations. To transform the fidelity of the representation of the boundary layer in numerical models, a comprehensive understanding of the multi-scale multi-physics interactions is necessary, which includes the modification of atmospheric turbulence by other processes and the emerging feedbacks. Also significant are the effects of spatial heterogeneity and temporal variability.

The scope of this Special Issue is broad and aims to include diverse methodologies and applications, such as energy harvesting and conversion, air quality and atmospheric dispersion. Submissions will encompass theoretical, modelling, and observation-based studies. Observational studies using in situ or remote sensing data and reduced models are particularly encouraged.

Towards Unifying the Planetary Boundary Layer and Shallow Convection in CAM5 with the Eddy-Diffusivity/Mass-Flux Approach

The modular structure of the boundary layer and convection parameterizations in atmospheric models have long been affecting the numerical representation of subgrid-scale motions and their mutual interactions. A promising alternative, the eddy-diffusivity/mass-flux approach (EDMF), has the potential for unifying the existing formulations into a consistent scheme and improving some of the long-standing issues. This study documents a step towards developing such a unified approach by implementing a stochastic multi-plume EDMF scheme into the Community Atmosphere Model (Version 5.0). Its performance in single-column mode is evaluated against the control parameterization and large-eddy simulation (LES) for two benchmark cases: marine and continental shallow convection. Overall, the results for the two parameterizations agree well with each other and with LES in terms of mean profiles of moist conserved variables and their vertical fluxes, as well as the updraft properties. However, systematic differences between the two schemes, especially for transient continental convection, are also documented. Using EDMF helps improve some of the parameterized features of shallow convection. In particular, for the highest tested vertical resolution, the EDMF cloud base and top heights and the vertical fluxes of energy and water are remarkably close to LES. Full article

Abstract: Wind energy has expanded rapidly in the past few years, increasing significantly its penetration and share in power systems worldwide. As higher wind energy penetration rates are achieved, conventional power plants will be displaced. This will introduce challenges in the operation of power systems, among them frequency regulation is highlighted. Because of that it may be required that wind farms contributes to frequency regulation by supporting grid stability with power reserve. The operation of wind farms under curtailment has been observed recently in different regions all over the world and probably it will be observed more frequently in the near future. Moreover, knowing the energy loss related to the operation of a wind farm under curtailment may be of interest for the power system operator, besides sometimes being required to compensate the wind farm owner. The main objective of this work is to simulate, based on a Large Eddy Simulation-Actuator Line Model framework, the operation of a 7.7MW onshore wind farm under curtailment. First, an event where the wind farm power production was limited by the power system operator is simulated to validate the numerical framework, comparing the results with data from the Supervisory Control And Data Acquisition system, and computing the energy loss. Then, the influence of different inflow conditions in the operation of the wind farm under the same restriction and in the related energy loss is assessed, focused on identifying the most important wind conditions.
