His researches delve into the characterization of the planetary boundary layer, with focus on the turbulent processes developing on morphologically complex terrains. Main research lines include stationary and non-stationary dynamics on sloping terrain, ventilation and air pollution removal in urban canopies with vegetation, multiscale dynamics of the urban heat island, turbulent processes within a saturated coastal fog environment. Developed expertise in measurements techniques and data analysis

- Interconnection between atmospheric dynamics, thermodynamics and turbulence with air quality and urban heat island in urban boundary layer. Implementation of different field experiments in real urban street canyons in presence of vegetation
An experimental field campaign is designed to unveil mechanisms responsible for turbulent exchange processes when mechanical and thermal effects are entwined. The focus is an urban street canyon with a mean aspect ratio H/W of 1.65 in the business centre of a mid-size Italian city (H is the mean building height and W is the mean canyon width). The...
Vegetation in the urban environment has various impacts on microclimate. While optimal strategies for investigating these impacts are the subject of ongoing research, most approaches rely on Computational Fluid Dynamics (CFD) simulations. We evaluate mean wind and turbulence fields simulated using the fast-running Quick Urban & Industrial Complex (...
The abatement performance of photocatalytic coatings on NOx concentrations in real-world street canyons remains an open question considering the very different conclusions reached by the few previous field studies. To fill this gap, an intensive experimental campaign was carried out in summer 2018 in the outskirts of Bologna in Italy. The experimen...
In the realm of boundary-layer flows in complex terrain, low-level jets (LLJs) have received considerable attention, although little literature is available for double-nosed LLJs that remain not well understood. To this end, we use the MATERHORN dataset to demonstrate that double-nosed LLJs developing within the planetary boundary layer (PBL) are c...
The presence of waves is proven to be ubiquitous within nocturnal stable boundary layers over complex terrain, where turbulence is in a continuous, although weak, state of activity. The typical approach based on Reynolds decomposition is unable to disaggregate waves from turbulence contributions, thus hiding any information about the production/des...
In this paper, an analytical model based on inertial oscillations (Van15 De Wiel et al, 2010) is used to replicate the evolution on a LLJ in complex terrain and then modified to diagnose the occurrence of a double-nosed LLJ driven by surface wave activity. Using an already-analysed case study from the Mountain Terrain Atmospheric Modeling and Obser...
Urban heat island (UHI) is a phenomenon associated to the different temperature diurnal cycle of the urban and surrounding rural environment, typically leading to higher air temperature in cities during the night. Heat waves (HWs) are intended as a climate related phenomenon associated to persistent high-pressure systems leading to high air tempera...
Anabatic flows are common phenomena in the presence of sloping terrains, which significantly affect the dynamics and the exchange of mass and momentum in the low-atmosphere. Despite this, very few studies in the literature have tackled this topic. The present contribution addresses this gap by utilising high-resolved large-eddy simulations for inve...
Thermal convective flows are common phenomena in real urban canyons and strongly affect the mechanisms of pollutant removal from the canyon. The present contribution aims at investigating the complex interaction between inertial and thermal forces within the canyon, including the impacts on turbulent features and pollutant removal mechanisms. Large...
The complex interaction between the Urban Heat Island (UHI), local circulation, and air quality requires new methods of analysis. To this end, this study investigates the multiple scale nature of the UHI and its relationship with flow and pollutant dispersion in urban street canyons with and without the presence of vegetation. Two field experimenta...
Motivated by the increasing interest on passive control solutions to lower pollutant concentrations in cities, this paper introduces a novel methodology to demonstrate the potential of photocatalytic coatings in abating air pollution in real-world urban environments. The methodology introduced in this paper is based on an original application of Co...
The European research and innovation project iSCAPE (Improving the Smart Control of Air Pollution in Europe) works on integrating and advancing the control of air quality and carbon emissions in European cities in the context of climate change through the development of sustainable and passive air pollution remediation strategies, policy interventions and behavioural change initiatives.
