Data-Driven Flux Parameterization for the Atmospheric Boundary Layer
Abed Hammoud, Edriss S. Titi, Mitchell Bushuk +3
Turbulent fluxes in the atmospheric boundary layer (ABL) govern exchanges of momentum, heat, and mass between the surface and atmosphere, shaping boundary layer structure and influ…
On the large-scale vertical velocity intermittency of turbulent wall flows
Tirtha Banerjee, Elia Buono, Costantino Manes +6
Large-scale intermittency in the vertical velocity (LSI) has received significant attention in studies of coherent structures and their detection using data-driven approaches. Howe…
Stratification, turbulence organization, and pressure-strain effects on surface-layer turbulence anisotropy
Ivana Stiperski, Gabriel G. Katul, Elie Bou-Zeid +1
At large scales, the Reynolds stress tensor exhibits notable anisotropy, a key feature of all wall-bounded turbulent flows. Yet, how the drivers of this anisotropy evolve with shea…
Train Long, Think Short: Curriculum Learning for Efficient Reasoning
Hasan Abed Al Kader Hammoud, Kumail Alhamoud, Abed Hammoud +3
Recent work on enhancing the reasoning abilities of large language models (LLMs) has introduced explicit length control as a means of constraining computational cost while preservi…
Estimating scalar turbulent fluxes with slow response sensors in the stable atmospheric boundary layer
Mohammad Allouche, Vladislav I. Sevostianov, Einara Zahn +5
Conventional and recently developed approaches for estimating turbulent scalar fluxes under stable conditions are evaluated. The focus is on methods that do not require fast scalar…
Unsteady Land-Sea Breeze Circulations in the Presence of a Synoptic Pressure Forcing
Mohammad Allouche, Elie Bou-Zeid, Juho Iipponen
Unsteady land-sea breezes (LSBs) resulting from time-varying surface thermal contrasts are explored in the presence of a constant synoptic pressure forcing, Mg, when the latter is…
Kirigami-inspired wind steering for natural ventilation
Lucia Stein-Montalvo, Liuyang Ding, Marcus Hultmark +2
Ensuring adequate ventilation of exterior and interior urban spaces is essential for the safety and comfort of inhabitants. Here, we examine how angled features can steer wind into…
The Influence of Synoptic Wind on Coastal Circulation Dynamics
Mohammad Allouche, Elie Bou-Zeid, Juho Iipponen
Particularly challenging classes of heterogeneous surfaces are ones where strong secondary circulations are generated, potentially dominating the flow dynamics. In this study, we f…
Contrasts Between Momentum and Scalar Transport Over Very Rough Surfaces
Qi Li, Elie Bou-Zeid
Large-eddy simulations are conducted to contrast momentum and passive scalar transport over large, three-dimensional roughness elements in a turbulent channel flow. Special attenti…
