This study aimed to analyze the shading effect of single trees on human thermal sensation (HTS) during summer. Microclimatic data were collected and analyzed in both sunny shaded locations for four tree species: one deciduous broadleaf (DBT), two evergreen (EBT), coniferous (ECT). The results showed relatively small differences air temperature, relative humidity, wind speed among mean 0.1-0.5 ℃, 0.5-1.8 %, 0.0-0.7 ms⁻¹, respectively. However, there was a significant difference radiant 18.6 ℃. Regarding HTS indices (PET UTCI), exhibited reduction rates 15.4-20.6 % PET, corresponding perception 1.0-1.5 levels. UTCI 9.7-12.5 equivalent heat stress 0.6-0.7 ECT demonstrated higher with 1.3 3.5 than DBT EBT, EBT similar as due its high leaf density. Based these findings, temperature density are primary factors influencing effects

The urban thermal environment is closely related to the well-being of many city dwellers. Rich achievements have been obtained for canopy layer heat island (CLUHI) studies. Nevertheless, monitoring and associated factors CLUHI not systematically timely reviewed. Therefore, this paper aimed solve issue some extent by reviewing fruitful research progress from above-mentioned two aspects. main findings were as follows. (1) Eight methods adopted obtain near-surface temperature data research, including four observation, numerical modeling, remote sensing assimilation methods. (2) Air was usually used rather than apparent indices. Obvious differences existed between them, especially under humid hot or cold windy conditions. (3) intensity generally defined in suburban rural stations regions population, land cover/land use, etc, derived using regression analysis impervious surface percentage. (4) diurnal, monthly, seasonal interannual variation has analyzed various global regions. (5) Six types analyzed, meteorological conditions, air pollution, socioeconomic factors, underlying condition, inland coastal type landform combined effects factors. (6) Five potential directions proposed, improvement acquisition, sharing considering indices, focus on rarely studied regions, cities scales, improving calculation intensity, attention more driving force This review can provide references future construction climate-resilient, livable, low-carbon cities.

Abstract This study examines the characteristics of urban heat island (UHI) in Dhaka, densely populated capital city Bangladesh under influence South Asian monsoon, and its interaction with waves. For this, meteorological data at Dhaka (urban) Madaripur (rural) stations reanalysis for period 1995–2019 are used analysis. Here, UHI intensity is defined as urban-rural difference 2-m temperature, a wave phenomenon which persists two or more consecutive days daily maximum temperature exceeding 90th percentile. The an increasing trend over past 25 years (0.21 °C per decade). average 0.48 °C. strongest winter (0.95 °C) weakest monsoon season (0.23 °C). In all seasons, 2100 LST. 2.15 Through multiple linear regression analysis, relative importance previous-day (PER), wind speed, humidity (RH), cloud fraction affect examined. pre-monsoon season, RH most important variable followed by PER. predominantly variable. post-monsoon winter, PER RH. occurrence frequency waves shows statistically significant (5.8 It found that associated mid-to-upper tropospheric anticyclonic-flow high-pressure anomalies low-to-mid season. Under waves, synergistically intensified both daytime nighttime (nighttime only) (monsoon) decreases favorable synergistic UHI-heat interaction.

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.

The synergistic interactions between urban heat islands (UHIs) and waves are of great concern due to their adverse impacts on residents scientific interest. Here, we examine the UHIs with two types waves, dry (DHW) moist (MHW). For this, Daegu, a large city in South Korea, is selected observational reanalysis data from 2001 2022 analyzed. DHW (MHW) defined as daily mean relative humidity lower (higher) than its 10th (90th) percentile. nighttime UHI intensity calculated using minimum 2-m temperatures stronger under by 1.07 °C weaker MHW 0.24 non-heat waves. This indicates DHW, but negative MHW. Evaluation four thermal discomfort indices shows that prominent UHI-heat wave can result similar or even greater stress compared for residents, despite humidity. study highlights necessity considering characteristics consequent assessing managing heat-related risks.
