Responses of the Urban Atmospheric Thermal Environment to Two Distinct Heat Waves and Their Changes With Future Urban Expansion in a Chinese Megacity

Geophysical Research Letters, Journal Year: 2024, Volume and Issue: 51(11)

Published: June 11, 2024

Abstract This study investigates the responses of urban atmospheric thermal environment to two distinct heat waves in Hefei, China, and explores potential changes associated with future expansion. During Event 1, characterized by clear dry conditions, western Pacific subtropical high limits water vapor influx, resulting a significant cooling effect rural area due higher surface latent flux. The island (UHI) intensity, calculated using temperature 2‐m temperature, reaches 5.2°C 1.7°C during respectively. Although 2, cloudy humid exhibits weaker UHI effects, it remains highly unfavorable for human comfort. waves, vertical extent warming induced expansion varies, which can be attributed environmental factors, such as stability near‐surface wind speed.

Study of the Correlation between the Urban Wind–Heat Environment and Urban Development Elements in High-Density Urban Areas: A Case Study of Central Shanghai

Buildings, Journal Year: 2024, Volume and Issue: 14(2), P. 315 - 315

Published: Jan. 23, 2024

To prevent damage to human life and health caused by high temperatures extreme weather promote sustainable urban development, it is necessary optimize the layout of development elements improve wind–heat environment. Taking high-density area Shanghai as an example, this study used wavelet analysis investigate cyclic changes average annual temperature from 1950 2022 wind speed 2000 2020. The correlation between heat environment was analyzed using geographically weighted regression. then examined BP neural network, finally, impacts different spatial patterns on were CFD numerical simulation. results show that city has overall upward trend, with significant cycles 44 32 years are shortening over time. a downward main cycle 22 years. Greening water coverage, well floor ratio, have reducing effect surface temperature, whereas building density positively correlated temperature. Building speed, ratio not significant. significantly weakened, This provides valuable references for other cities in order safety comfort environments. importance value promoting protecting residents, advancing justice equal well-being.

Efficiency of urban greening systems with maximized latent heat effect in urban heat island and climate change mitigation

Environmental Challenges, Journal Year: 2024, Volume and Issue: 15, P. 100956 - 100956

Published: April 1, 2024

Street, wall, and rooftop greening systems are essential for urban heat reduction carbon neutrality. In this study, we compared the temperature-reducing effect of current developed technologies that maximize latent evaporation through such systems. A research site with maximum island was selected by analyzing vulnerability Suwon City, Korea. The each method determined conducting actual measurements verified performing computational fluid dynamics simulations. Based on results statistical techniques, validated model highly reliable. When were applied, temperature entire city reduced approximately 2°C. Compared existing street system, technology achieved a even at distance 5 m. Current wall only have 1 m, but 1°C 2 system had height 1.2 whereas effective 6 contributing to in city.
