Urban scale phenomena and boundary layer processes in mountain valleys
… meteorological WRF model, coupled with the multilayer Building Environment Parameterization (BEP) scheme, are utilized to study the urban climate of Trento in the Adige Valley context. Suitable datasets of land use, urban morphology and anthropogenic heat flux have been specifically prepared for …

Study of the atmospheric boundary layer processes over sloping terrain covered by sparse canopy
… aim of this thesis is the study of the exchange processes at atmosphere/biosphere interface, with a particular focus on momentum and heat transport over complex terrain morphology, varying surface roughness, and a wide range of atmospheric thermal conditions. The surface roughness object of the …

Nonlinear equilibration of baroclinic eddies : the role of boundary layer processes and seasonal forcing
In this thesis, the influence of boundary layer processes and seasonal forcing on baroclinic eddy equilibration is studied to understand how the baroclinic adjustment is modified when taking into account these two factors. A modified [beta] plane multilevel quasi-geostrophic (QG) model with an …

Determining potential for pollutant impacts in dynamic coastal waters: comparing morphological settings
… determined by the dynamics of the coastal boundary layer (CBL). This turbulent interface between the coastline and the deep oceans is defined and classified for the first time in this thesis. Coastal morphologies and changes in the orientation of the coastline promote turbulence and strong …

Area-average representation of land surface covers in large atmospheric models based on remotely sensed land surface cover data
… representation of both surface and atmospheric boundary layer processes, and to use this model to simulate surface-atmosphere interactions with explicit representation of patches of vegetation on the one hand, and with a single, area-average representation of exchanges on the other. These …

Boundary layer dynamics and deep ocean mixing in Mid-Atlantic Ridge canyons
… currents and mixing, I studied diffusive boundary layers over varying topography using theoretical approaches and idealized numerical simulations using the ROMS model. In this dissertation, I show a variety of previously unidentified characteristics of diffusive boundary layers that are …

Importance of boundary layer entrainment for surface fluxes over land
… sheds some light on the spatial heterogeneity of boundary layer processes. The derived depths are shallower over water than over land and show a local minimum along the Mississippi River valley. Deeper features are found over the desert Southwest and deeper than expected values are retrieved over …

Ice shelf-ocean interactions in a general circulation model : melt-rate modulation due to mean flow and tidal currents
… requires parameterizing the turbulent boundary layer processes to infer melt rates from the oceanic state at the ice-ocean interface. Here we explore two such parameterizations in the context of the MIT ocean general circulation model coupled to the z-coordinates ice shelf cavity model …

Applicability of weight-shift microlight aircraft for measuring the turbulent exchange above complex terrain
… to; (i) limitations in the description of boundary layer processes over non-homogenous terrain, and (ii) a lack of applicable measurement platforms and techniques to study these processes. In pursue of a resolution strategy, this dissertation investigates the applicability of weight-shift …
