A multi-scale approach combining MOLOCH and PALM-4U for simulating urban micro-meteorology in an italian neighborhood Open
City development has significantly transformed local climate conditions, modified wind patterns, and variations in altered air quality. These transformations have important consequences for human health, energy usage, and environmental sus…

Coherent structures detection within a dense Alpine forest Open
The influence of coherent vortices on the turbulence structure above and below a dense plant canopy is investigated using turbulence measurements collected at five levels on top and inside a coniferous forest on an Alpine Plateau. Five dif…

Law-of-the wall adjustments above the Amazon Forest via Cospectral Budget Model Open
Measurements collected at two experimental sites, the Amazon Tall Tower Observatory (ATTO) and the tower at the Cuieiras Biological Reserve (ZF2) that was part of the GoAmazon experiment, were considered to study deviations from the law-of…

Assessing the Departures from the Energy- and Flux-Budget (EFB) Model in Heterogeneous and Urbanized Environment for Stable Atmospheric Stratification Open
Turbulence closure schemes, besides their intrinsic theoretical importance, represent a fundamental component in the atmospheric numerical models. Among his numerous and diverse scientific contributions, Prof. Sergej S. Zilitinkevich, with…

Adjustments to the law of the wall above an Amazon forest explained by a spectral link Open
Modification to the law of the wall represented by a dimensionless correction function ϕRSL(z/h) is derived using atmospheric turbulence measurements collected at two sites in the Amazon in near-neutral stratification, where z is the dista…

Influence of submeso motions on scalar oscillations and surface energy balance Open
The presence of wave‐like structures in the planetary boundary layer and their influence on the scalar fluxes and on the surface energy balance were investigated analyzing one year of continuous measurements collected in southern Brazil. S…

A wavelet analysis of low‐wind‐speed submeso motions in a nocturnal boundary layer Open
In low‐wind regimes (wind speed less than 1.5 m s −1 ) the nocturnal boundary layer is still inadequately understood. In such conditions, turbulence is weak and often intermittent, whereas dynamics and total fluxes are often driven by subm…

Characteristics of Gravity Waves over an Antarctic Ice Sheet during an Austral Summer Open
While occurrences of wavelike motion in the stable boundary layer due to the presence of a significant restoring buoyancy force are rarely disputed, their modalities and interaction with turbulence remain a subject of active research. In t…
