This study aims to investigate the impact of complex urban morphology on the wind environment characteristics, and thereby to establish an urban wind profile at local scale. Firstly, the Weather Research and Forecasting (WRF) model combined with Local Climate Zone (LCZ) method was used to simulate the urban wind field. Subsequently, the simulated data was validated against wind speed data from meteorological stations and sounding data. Finally, the logarithmic law wind profile parameters were analyzed corresponding to each LCZ type (LCZ1-LCZ6) within varying spatial extent by statistical methods, and thus the optimal parameters were obtained applicable to these types. The results indicated that roughness length and friction velocity were strongly correlated with the LCZ type; based on the spatial layout, the optimal ranges for each LCZ type were determined, with roughness length ranging from 5.70 m to 11.95 m and friction velocity ranging from 0.783 m/s to 0.883 m/s. Logarithmic law wind profiles were established applicable to each LCZ type.","PeriodicalId":48626,"journal":{"name":"Urban Climate","volume":"88 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted three one-month simulation tests to quantify the impact of urban hydrological processes on urban climate, which is induced by urban ground greening, green roofs and surface water. It is found that urban hydrological processes significantly reduce maximum temperatures and improves comfort, especially during heatwaves, but its effect on mean air temperature was found to be less pronounced. Compared to ground greening, green roofs provide enhanced cooling advantages. Overall, all three hydrological processes produce a more spatially dispersed distribution of precipitation with a reduction of 25 % in total precipitation amount. This can be attributed to the mitigation of urban heat island intensity by latent heat and the stabilization of the planetary boundary layer. The finding has implication for the measures that can be taken in mitigating the adverse impact induced by rapid urban expansion.","PeriodicalId":48626,"journal":{"name":"Urban Climate","volume":"167 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through the application of bivariate polar plots and hotspot mapping, we linked major particulate matter sources to industrial activities especially steel plant emissions, and road traffic, which significantly elevated the particulate matter levels in residential and industrial zones. Our time-series clustering analysis further distinguishes traffic and industrial activities as key contributors to particulate matter pollution.

However, due to a scarcity of high-precision historical street thermal environment data for prediction and modeling, existing urban thermal environment classification assessment studies suffer from low resolution (&gt; 30 m) or limited research scope (e.g., community-level), resulting in less accurate and comprehensive insights. This study introduces an innovative framework for constructing large-scale urban street-level thermal gradients using classified samples derived from the spatial structural features of street points. The core of this framework lies in the k-means unsupervised classification algorithm. This approach integrates detailed local geographic information system (GIS) data with street view features, calculated through semantic segmentation of Google Street-View-Panorama using the DeepLabV3 model. This allows for the categorization of a vast array of high-precision street points based on spatial structural similarity, a key factor influencing the similarity of street thermal environment features. By selecting appropriate samples for on-site thermal environment measurements within each category and subsequently extrapolating this knowledge to the thermal environment classification of each category, this framework facilitates the rapid creation of high-precision street-level thermal gradient models across extensive urban areas.","PeriodicalId":48626,"journal":{"name":"Urban Climate","volume":"268 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a hybrid deep learning model based on TimesNet, Crossformer and Modified Honey Badger Algorithm (MHBA) for air quality prediction. First, the original air quality index (AQI) series is decomposed using Seasonal-Trend decomposition based on Loess (STL). Then, the decomposed three components are predicted separately using TimesNet and Crossformer, while the hyperparameters of TimesNet and Crossformer are optimized using the Metis algorithm. In addition, half uniform initialization and Levy flight are added to the original HBA algorithm to make up for its shortcomings of slow optimization search speed and the tendency to fall into local optimal position, and the MHBA algorithm is obtained. Finally, the MHBA algorithm is used to weight the component prediction results of the two models, and compare the advantages and disadvantages of different weighting methods, and select the optimal weighting method to get the final AQI prediction results. The experimental results show that the STL-Metis-MHBA-TC model reduces RMSE, MAE, and MAPE by 19–34 %, 22–38 %, and 22–44 %, respectively, compared to the Transformer model. Therefore, the STL-Metis-MHBA-TC hybrid model proposed in this paper can effectively improve the AQI prediction accuracy.","PeriodicalId":48626,"journal":{"name":"Urban Climate","volume":"24 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distinguishing between local pollution and transboundary contributions is crucial for accurately assessing the health risks to local populations. This study aimed to analyze the differences in coarse and fine particulate matter and develop methods to obtain exposure data for epidemiological studies, thereby providing a scientific basis for public health interventions. We collected SPM-PM<ce:inf loc=\"post\">2.5</ce:inf> (physically excluded PM<ce:inf loc=\"post\">2.5</ce:inf> from SPM) and PM<ce:inf loc=\"post\">2.5</ce:inf> samples in Yonago City, a coastal urban area in Tottori Prefecture, Japan, from 19 October 2015 to 25 July 2016 using a novel slit jet impactor (MCAS-SJ). Positive matrix factorization analysis used heavy metal, ion, and carbon concentrations to identify pollutant sources. This study identified four major air pollution events during the sampling period, primarily attributed to transboundary transport. Episode I was dominated by nitric aerosols, Episodes II and III by Asian dust, and Episode IV by sulfate aerosols. An analysis using global chemical transport models and backward trajectories confirmed that these events verified the contribution of transboundary pollution. In conclusion, identifying the impact of transboundary pollution on local air quality enables an accurate risk assessment of populations. This study provides scientific evidence for developing effective public health strategies and preventive measures. Additionally, the methodology used in this study holds the potential for international contributions and future research applications, helping to address air pollution challenges on a broader scale.","PeriodicalId":48626,"journal":{"name":"Urban Climate","volume":"114 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking the “Green Heart” area of the Changsha-Zhuzhou-Xiangtan urban agglomeration, and utilizing land use datasets between 1990 and 2020, numerical simulations of near-ground air temperatures were conducted to analyze the temperature variations induced by the spatial dynamics and the land-use change inside the Green Heart. The findings reveal a 0.4 °C increase in urban temperatures caused by urban expansion. A “cool island effect” by the Green Heart is observed but the temperature difference achieved (2 °C to 4 °C) is no more significant than in city-scale parks and the cooling extent beyond the Green Heart's perimeter was insignificant. Doubling the construction land inside the Green Heart increased daytime and nighttime temperatures by 1.5 °C and 2.6 °C, respectively, suggesting the importance of maintaining forests. The long-term urban temperature fluctuations are arguably influenced more by the spatial transformations inside the cities than changes inside the Green Heart. These results imply that combating urban heat should prioritize city-centered cooling strategies and land-use control.","PeriodicalId":48626,"journal":{"name":"Urban Climate","volume":"86 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, there are very few long-term monitoring studies that assess the net impacts of pedestrianisation on air quality and noise. This study uses a dense low-cost particulate matter and environmental noise monitoring network to assess the net impacts of the Strand-Aldwych pedestrianisation project (SAPP) in central London on particulate matter and noise pollution. Monitoring started before traffic was excluded from the Strand in June 2021 and continued through re-development works in 2022 and post-works in 2023. Collected particulate matter data was complemented with data from the Automatic Urban and Rural Network and London Air Quality Network sites. Results show a statistically significant decrease in NO<ce:inf loc=\"post\">x</ce:inf> and environmental noise pollution on the Strand between summer 2021 and summer 2023. PM<ce:inf loc=\"post\">2.5</ce:inf> levels have also decreased at street level on the Strand but have increased on Aldwych and other surrounding streets relative to concurrent background levels measured at roof level. PM<ce:inf loc=\"post\">2.5</ce:inf> is mostly driven by larger scale background inputs in central London and meteorological conditions while NO<ce:inf loc=\"post\">x</ce:inf> and environmental noise are more directly related to local sources at street level.

The results show: (1) Land resource mismatch significantly inhibits the performance of urban energy low-carbon transition, and the conclusion still holds after a series of robustness tests such as replacing explanatory variables and endogeneity analysis. (2) Land resource mismatch mainly affects the urban energy low-carbon transition by inhibiting industrial structure upgrading, low-carbon technology innovation and weakening industrial agglomeration effects. (3) The disincentive effect of land resource mismatch is more pronounced in resource-based cities, cities with low cleaning potential and small-scale cities.
