Summary: This study investigated the seasonal thermal and moisture behavior of the urban metropolitan area of Turin in Italy in relation to its rural surroundings. The analysis revealed the presence of the Urban Heat Island (UHI) effect, with the highest temperature differences occurring during the night. A slight Urban Cool Island (UCI) effect and an Urban Dry Island (UDI) effect were also identified under certain conditions. The study also found that the urban-rural differences are reduced with increasing wind velocity. The analysis of temperature data collected from various stations allowed for the investigation of the city boundary layer, with the UHI effect reaching a vertical limit of 150-200 m above the ground level in most cases.

Summary: This study investigates the impacts of urban heat advection (UHA) on local urban heat island (UHI) using weather data and numerical simulations. The results show that the upwind land surface characteristics modify UHI, and the downwind areas of impervious and pervious surfaces are influenced by warmer and cooler air advection, creating temperature contrasts during the day and night-time.

Summary: This study implemented and verified four urban configurations of the Weather Research and Forecasting model for the coastal metropolitan area of Tel-Aviv, focusing on the mesoscale summertime flow dynamics and the role of urban canopy in hodograph dynamics at night. The simulations showed that the MM and SLUCM configurations were more accurate for diurnal temperature and wind cycles, while SLUCM exhibited lower skill in wind speed and BEP underestimated 2-m temperature. The study suggests a need for reexamination of the SLUCM wind speed parameterization.

Summary: Turbulent mixing in the planetary boundary layer plays a critical role in the vertical exchange of heat, moisture, momentum, trace gases, and aerosols. This study examines the spatial patterns of long-term PBLH trends over land and finds consensus on increasing PBLH over the Sahara Desert and Arabian Peninsula and declining PBLH in India. The changes in PBLH are significantly correlated with changes in surface heating and moisture at the global scale.

Summary: The interaction between aerosols and the planetary boundary layer has a significant impact on urban air quality. This study focused on the complex feedback of aerosols on the Beijing megacity and found notable distinctions in aerosol properties and vertical distributions among different air masses. Aerosols consistently suppressed the daytime convective boundary layer, indicating the potential complexity of aerosol-PBL interactions in future scenarios and other urban regions.

Summary: Urban heat islands (UHIs) and urban cool islands (UCIs) play significant roles in influencing urban precipitation. The variations in anthropogenic heat flux (AH) and building height (ZR) affect urban precipitation, with AH increasing precipitation during daytime and ZR increasing surface temperature and precipitation during nighttime.

Summary: This study evaluates the impact of different land surface models and planetary boundary layer schemes on the simulation performance in semi-arid regions using the WRF model. The results show that the land surface model plays a crucial role in driving the differences between simulations, while the planetary boundary layer scheme has minor influence.

Summary: The relationship between electricity consumption and outdoor air temperature in the Tokyo Metropolitan Area was analyzed using data from 1290 substations. The study revealed temporal-spatial variations in the sensitivity of electricity consumption to temperature. The results have implications for the development of efficient energy management systems and improvement of urban climate and building energy models.

Summary: The correction scheme proposed in this study improves the quality of CALIPSO aerosol optical depth by assuming a uniform distribution of aerosols below the planetary boundary layer. Validation against ground-based sites in eastern China showed that the correction method enhanced the accuracy of CALIPSO AOD data.

Summary: This work assesses the performance of the drag-porosity model implemented in ARPS atmospheric Large-Eddy Simulation (LES) solver for simulating the atmospheric boundary layer over the urban canopy. The flow over an idealized urban canopy consisting of cubes with various packing densities is investigated. The model is able to reproduce the key features of the flow over urban terrain, including turbulent coherent structures and their characteristic scales.

Summary: The Chengdu Metropolitan Area has undergone decades of urban and rural integration development. The vulnerability and security of the ecological environment have become critical considerations due to rapid urbanization and population growth. This study proposes a growth boundary study based on the theory of urban vitality and ecological networks, aiming to identify inefficient urban land and urban development potential land and simulate spatial patterns for the next 15 years. The results demonstrate the accuracy and effectiveness of the proposed model in simulating urban growth and supporting government decision-making.

Summary: This study investigates the impact of highway expansion on urban development in the Jakarta Metropolitan Area (JMA). The results show that highway improvement leads to urban expansion and sprawl, particularly within a 40-50 km radius from the city centre.

Summary: This study focuses on improving the representation of PM episodes in the Berlin agglomeration area using test-case studies with the LOTOS-EUROS CTM. The mixing layer height (MLH) is identified as a major impact factor, and applying the COSMO-CLM model significantly improves the meteorological representation of the PBL and MLH. A multi-level approach excluding the MLH leads to a considerable increase in the total PM mass concentration amount.
