“…The absence of humidity effects on mortality is further supported by studies which have compared heat indices (biometeorological measures combining temperature and humidity) with that of dry bulb temperature (a measure of temperature only) in their respective abilities to predict mortality and have found no consistent advantage in one over the other (Barnett et al, 2010;Ragettli et al, 2017). On the other hand, a number of studies have demonstrated an association between humidity and mortality, including cardiovascular mortality and mortality in the elderly (de Barros et al, 2021;Dilaveris et al, 2006;Ou et al, 2014;Qi et al, 2020). Indeed, we previously demonstrated the effect of humidity on respiratory mortality (Akasheh et al, 2018).…”

The full effects of meteorological variables on mortality have not yet been elucidated. This study's aim was to investigate whether 30-day in-hospital mortality in emergency hospital admissions for non-respiratory diseases were sensitive to the effects of humidity and ambient temperature on the day of admission. We studied all emergency medical admissions to St. James's Hospital, Dublin, during 2002Dublin, during -2018 and investigated temperature and humidity on day of admission. We employed multivariable logistic regression to identify temperature and humidity mortality predictors, adjusting for underlying comorbidities. Lower temperatures on day of admission predicted higher 30-day in-hospital mortality (adjusted OR: 1.12, 95% CI: 1.06-1.17), but lower humidity levels did not (adjusted OR: 0.97, 95% CI: 0.91-1.03). There was no interaction between meteorological variables and comorbidities on mortality. In conclusion, temperature may be a more significant predictor of inhospital mortality than humidity for non-respiratory patients.

Outdoor Human Thermal Comfort along Bike Paths in Balneário Camboriú/SC, Brazil

et al. 2022

This research is concerned with understanding the degree of human thermal (dis)comfort in connection with the various microclimates present in the vicinity of bike trails in Balneário Camboriú/SC, Brazil, throughout the summer. Local Climate Zones were determined using the Sky View Factor and were identified along research routes and schedules at 9:00 a.m. and 4:00 p.m. on a subtropical summer day (14 January 2022). Data were collected with weather devices attached to the bicycle, measuring air temperature, relative humidity, and globe temperature, from which the mean radiant temperature was calculated. The PET and UTCI indices were used to assess outdoor thermal comfort in the summer. The findings revealed that at 9:00 a.m., the eastern half of the city had a higher tendency for thermal discomfort; however, at 4:00 p.m., this same location had thermal comfort for users along bike routes. At 4:00 p.m., the PET index indicated that 24% of the bike paths were pleasant, and the UTCI index indicated that 100% of them were in thermal comfort. At 9:00 a.m., the majority of the city was under discomfort conditions. The index values reflect the morning time, and the study shows that there is now a negative correlation between the SVF and the indexes, which means that the greater the SVF computations, the lower the values are. The PET and UTCI indices revealed a positive association in the afternoon period: the greater the SVF values, the higher the PET and UTCI indices. Further research should be conducted in the future because many parameters, such as construction, position, and urban (im)permeability, as well as sea breeze and solar radiation, can have a significant impact on outdoor human thermal comfort in Balneário Camboriú, and when combined with the type of LCZ and the SVF, it is possible to understand how all of these active systems interact and form microclimates that are beneficial to bike path users.

The Role of Canary Island Date Palms in Physical Amenity Provisioning for Urban Landscape Settings

Canary Island date palms (Phoenix canariensis) have been planted as a landscaping feature plant throughout warm, temperate, and subtropical climates. The physical amenity provisioning of this species (shade effects, microclimate amelioration, water usage, etc.) has so far not been systematically assessed. This paper reports on temperature and humidity measurements in both a suburban and a rural location in SE Australia. The study demonstrates the effects of the palm canopy as regulator of humidity and provider of shade and, thus, amenity values in urban landscape settings. Drawing on published energy savings and growth requirements of the plant, the paper argues that Canary Island date palms are landscaping plants suitable to ameliorate the microclimate in urban neighborhoods with varied socio-economic conditions.
