Cities lack the resilience to withstand extreme events\, and the vulnerability of urban dwellers is elevated. Today\, air quality and thermal comfort deterioration in urban e nvironments are central concerns that shape mitigation policies and urban climate research. However\, finding an appropriate way to understand the l ocal urban atmosphere\, recognise issues\, and produce reliable informatio n and solutions is complex and multibranched. It requires not only high-en d numerical tools\, software\, observation networks\, and urban datasets\, but also careful planning\, interpretation\, and cooperation between the expert community and public administration.\n\nThe cornerstone of any scie ntific investigation of certain phenomena lies in understanding the physic al processes that drive them and govern their evolution. The physical fram ework of the urban boundary layer is a delicate balance of various physica l processes that affect the urban atmosphere\, airflow\, and phenomena wit hin it. This framework is simultaneously influenced by urban morphology an d the specificity of settlement patterns. Despite being distinctive on a b roader scale\, urban areas share a common trait of being heterogeneous wit h a range of artificial and natural surfaces covering them. Along with lar ge-scale atmospheric dynamics\, human activities\, etc.\, these traits mak e cities hotbeds for turbulence generation. Turbulence is a governing mech anism shaping urban atmospheric behaviour\, energy balance\, pollutant tra nsport\, and street-scale airflow dynamics. It is certainly fundamental an d needs to be adequately resolved\, with its influence on the urban atmosp heric processes accurately represented in the models. Resolving the urban morphology and the boundary layer on a fine scale via numerical models is a prerequisite for understanding urban ventilation\, air quality\, and the rmal comfort and progressing in climate change adaptation and mitigation.\ n\nThis presentation addresses these critical urban climate issues by util ising Large-Eddy Simulation (LES) to achieve high-resolution\, street-scal e modelling. The Parallelized Large-Eddy Simulation Model (PALM)\, a state -of-the-art computational framework designed specifically for the urban ca nopy is introduced. The presentation will detail PALM’s advanced capabil ities\, including its sophisticated treatment of urban surfaces\, plant ca nopy effects\, and high-resolution turbulence resolving features.\n LOCATION:https://researchseminars.org/talk/MathMAC/56/ END:VEVENT END:VCALENDAR
