“…Relevant studies have suggested that with the changes of meteorological factors over the past few years, the suitability of meteorological factors for infectious diseases (e.g., dengue fever, malaria and pathogenic Vibrio) has increased (6). In addition, extreme meteorological factors (e.g., extreme temperature, extreme humidity, and extreme wind speed) significantly affected various infectious diseases (7)(8)(9)(10). As a respiratory infectious disease, PTB exhibits seasonal characteristics (11), primarily due to meteorological factors (12,13).…”

BackgroundMost existing studies have only investigated the delayed effect of meteorological factors on pulmonary tuberculosis (PTB). However, the effect of extreme climate and the interaction between meteorological factors on PTB has been rarely investigated.MethodsNewly diagonsed PTB cases and meteorological factors in Urumqi in each week between 2013 and 2019 were collected. The lag-exposure-response relationship between meteorological factors and PTB was analyzed using the distributed lag non-linear model (DLNM). The generalized additive model (GAM) was used to visualize the interaction between meteorological factors. Stratified analysis was used to explore the impact of meteorological factors on PTB in different stratification and RERI, AP and SI were used to quantitatively evaluate the interaction between meteorological factors.ResultsA total of 16,793 newly diagnosed PTB cases were documented in Urumqi, China from 2013 to 2019. The median (interquartile range) temperature, relative humidity, wind speed, and PTB cases were measured as 11.3°C (−5.0–20.5), 57.7% (50.7–64.2), 4.1m/s (3.4–4.7), and 47 (37–56), respectively. The effects of temperature, relative humidity and wind speed on PTB were non-linear, which were found with the “N”-shaped, “L”-shaped, “N”-shaped distribution, respectively. With the median meteorological factor as a reference, extreme low temperature was found to have a protective effect on PTB. However, extreme high temperature, extreme high relative humidity, and extreme high wind speed were found to increase the risk of PTB and peaked at 31.8°C, 83.2%, and 7.6 m/s respectively. According to the existing monitoring data, no obvious interaction between meteorological factors was found, but low temperature and low humidity (RR = 1.149, 95%CI: 1.003–1.315), low temperature and low wind speed (RR = 1.273, 95%CI: 1.146–1.415) were more likely to cause the high incidence of PTB.ConclusionTemperature, relative humidity and wind speed were found to play vital roles in PTB incidence with delayed and non-linear effects. Extreme high temperature, extreme high relative humidity, and extreme high wind speed could increase the risk of PTB. Moreover, low temperature and low humidity, low temperature and low wind speed may increase the incidence of PTB.

Urban green space (UGS) could contribute to sustainable urban development. Studying residents’ perception of UGS ecological benefits could provide the empirical basis to improve UGS management and quality of life. Based on the questionnaire surveys of 432 residents in Beijing, assisted by non-parametric statistical tests, this paper assessed the relationships between residents’ living environments and self-rated health status and their impacts on residents’ perceptions of UGS ecological benefits. We paid attention to residents’ perceptions of UGS’s notable thermal environmental benefits under the climate-change backdrop. The results showed that: (1) Residents were inclined to perceive direct UGS ecological benefits better than the indirect types; (2) Residents growing up in the city had better self-rated health status than those growing up in the suburb and the village; and residents growing up in the suburb had a better understanding of the cooling benefits of green walls; (3) Residents currently dwelling in the city had a better understanding of UGS benefits, including shading, cooling by green roofs, mitigating the heat island effect and enhancing urban biodiversity, than those dwelling in the village; and (4) Residents with “very good” self-rated health status had a significantly better understanding of UGS benefits regarding shading, providing varied colors and habitats, storing carbon, purifying air, and collecting rainwater.

“…The increase in urban heat island intensity (UHII) worldwide has affected urban dwellers' physical and mental health and raised heat-related morbidity and mortality problems, such as neurological diseases and respiratory diseases, even could lead to death due to heat wave. 7,8 UHI could also increase urban energy consumption, [9][10][11][12] resulting in the increased carbon emission. 13,14 This is, therefore, contrary to the China's Carbon Neutrality Plan, 15 and to the Paris Agreement.…”

The impact of PM2.5 pollution and urban heat island (UHI) on sustainable urban development and human health has been a major concern for governments. Based on Computational Fluid Dynamics (CFD) simulation and on-site monitoring, this study investigated the airflow velocity, PM2.5 concentration and urban heat island intensity (UHII) distribution in the urban area at different prevailing wind directions, from the perspective of urban design. In order to validate the accuracy of CFD simulation results, on-site monitoring of temperature and airflow velocity was conducted on the roof of a building. A low-dimensional model was adopted to improve the efficiency of CFD data analysis. Moreover, based on the results of the low-dimensional model, PM2.5 concentration and UHII in urban areas at different prevailing wind directions were assessed by clustering analysis. The findings showed that when α = 0° and 90°, the average PM2.5 concentration was 28.9–56.8% (8.76–27.66 μg/m³) lower and the average UHII was 23.4–34.2% (0.8–1.15°C) higher, compared to α = 30°, 45° and 60°. Meanwhile, the downwind area suffers from more serious PM2.5 pollution and UHII than the upwind area. These findings could potentially provide a guide for future building/urban design to improve the urban environment from the perspective of building and road construction.
