Summary: This study proposes a statistical strategy for estimating next-day nighttime Surface Urban Heat Island (SUHI) intensity using a support vector machine regression model. Various SUHI controls were incorporated, leading to estimations for 59 Chinese megacities. The analysis revealed that relative humidity has the greatest contribution to SUHI estimation.

Summary: This study focuses on analyzing the daily variations of surface urban heat islands (SUHIs) over Chinese cities and their correlations with various explanatory factors. The results show that weather conditions have a significant impact on SUHI intensity, while temperature fluctuations mainly influence SUHI extent, shape, and centroid direction. Antecedent precipitation plays a substantial role in influencing subsequent SUHIs under clear skies. The meteorological contributions to daily nighttime SUHIs varied among Chinese cities with different bioclimatic conditions.

Summary: By 2050, a significant increase in the global and UK urban population is expected. Urban areas are hotter than rural areas, and higher temperatures in summer lead to increased morbidity and mortality. Understanding the future changes in urban heat island (UHI) intensity is crucial. Recent research suggests that UHI intensity may decrease with warming temperatures. This study analyzes the ability of the UKCP18-regional model to simulate the summer nighttime UHI intensity in ten UK cities and finds good agreement with observational data. However, the projected future UHI intensities are not significantly correlated with the historical daily UHI-temperature relationships, and the model-projected change in UHI intensity is greater than the change inferred from the historical relationship for all cities analyzed.

Summary: In semi-arid urban environments, different urban landcovers (ULC) have different influences on local air temperatures. Urban tree canopy can reduce daytime temperatures, while impervious surfaces and buildings can increase daytime temperatures. During nighttime, irrigated turf can cool down temperatures, while tree canopy has less cooling effect. ULC drives around 17% and 25% of local air temperature during the day and night, respectively.

Summary: Climate change presents an unprecedented challenge to public health, with extreme temperatures being one of its main direct effects. The variance in temperature within urban areas, known as the surface urban heat island (SUHI) effect, was assessed in Lima, Peru. Land surface temperature (LST) was estimated using satellite data and socioeconomic data were obtained from the census. The study found that blocks with higher socioeconomic status had reduced exposure to SUHI compared to those with lower socioeconomic status. It also revealed significant variations in SUHI exposure among different ethnicities. These findings emphasize the importance of addressing socioeconomic inequalities when designing urban adaptation strategies to mitigate SUHI exposure.

Summary: This study investigated the day-to-day variations of Surface Urban Heat Island (SUHI) intensity (SUHII) in over 10,000 cities worldwide, and found that meteorological variables related to thermal admittance have a larger regulation on SUHII variations than those related to air conditions. The study also found that the impact of meteorological factors on SUHII variations differs greatly by background climates, with specific humidity having a significant control in arid zones and wind speed being weakened prominently in equatorial zones. Furthermore, precipitation was observed to mitigate SUHII variations globally, particularly in equatorial and arid zones.

Summary: The study found that in a tropical climate, the surface temperature of red and grey concrete pavers was lower by 4.2 degrees and 4.5 degrees compared to black pavers, respectively. Among the grey pavers, the smooth texture showed up to 2.6 degrees lower temperature retention. The red jagged concrete paver had the lowest surface temperature, minimizing the pavement's contribution to the Urban Heat Island effect.

Summary: Despite being relatively understudied, nighttime heatwaves in Africa, especially in rapidly expanding urban areas, have dramatically increased during 1981-2020 due to urbanization and large scale circulation induced dry conditions. The strongest contribution of urbanization to nighttime heatwaves was observed in temperate climate, while in arid climate, urban expansion had a negative impact on nighttime heatwaves. Without appropriate adaptation efforts, the risks posed by heatwaves in Africa's urban areas will continue to increase under future warming.

Summary: This study investigates the synergistic effect of urban heat island (UHI) and urban moisture island (UMI) on heat stress during hot summers. In compact high-rise cities, anthropogenic heat emissions from building cooling systems play a significant role. The interactions between buildings, trees, and air in compact high-rise street canyons are complex, impacting UHI and UMI. Planting trees can reduce UHI but increase UMI, requiring optimized tree planting strategies.

Summary: This research assesses the effect of the composition and structure of urban trees on the Urban Heat Island (UHI) phenomenon in the south of Chile. The study finds that the shape and quality of trees have a significant impact on temperature oscillations, and better quality and larger canopy area favor the cooling process. Additionally, there are differences in behavior between native and introduced tree species, although they are not significant. Proper management of urban green infrastructure is important for addressing the UHI phenomenon.

Summary: Urban sprawl has led to changes in landscaping, replacing open areas and green urban spaces with buildings and infrastructure. This transformation has resulted in the Urban Heat Island (UHI) effect, causing urban centers to be warmer than rural areas. The research aims to assess the impact of green urban spaces' area and building formation on the exacerbation of UHI in Baghdad city.

Summary: This study used Landsat 8 satellite data and MODIS products to create time series land surface temperatures for analysis of the seasonal variations in surface urban heat island (SUHI) in Xi'an, China. The results showed that open building types generally have lower land surface temperatures than compact building types. The highest SUHI intensity was observed in compact mid-rise buildings (LCZ2) in July, while the lowest was observed in open high-rise buildings (LCZ4). The SUHI intensity peaked about 17-23 days later than the background land surface temperatures. The annual SUHI hysteresis cycles exhibited an anti-clockwise concave-up pattern in the monsoon-influenced hot-summer humid continental climate (Dwa per Ko center dot ppenGeiger climate scheme). The SUHI intensity in autumn was higher than in spring under the same background land surface temperatures. These findings provide valuable information for developing heat mitigation strategies in different seasons.
