Modelled spatiotemporal variability of outdoor thermal comfort in local climate zones of the city of Brno, Czech Republic

摘要: This study uses the MUKLIMO_3 urban climate model (in German, Mikroskaliges Urbanes KLImaMOdell in 3-Dimensionen) and measurements from an network order to simulate, validate analyse spatiotemporal pattern of human thermal comfort outdoors city Brno (Czech Republic) during a heat-wave period. HUMIDEX, heat index designed quantify exposure, was employed assess comfort, employing air temperature relative humidity data. The divided into local zones (LCZs) access differences intra-urban comfort. Validation results, based on measurement dates within monitoring network, confirmed that micro-scale had capacity simulate main patterns area its vicinity. results suggested statistically significant outdoor exist majority cases between different LCZs. most built-up LCZ types (LCZs 2, 3, 5, 8 10) were disclosed as uncomfortable areas city. Hence, conditions great discomfort (HUMIDEX >40) recorded these areas, mainly afternoon hours (from 13.00 18.00 CEST), while some continued overnight. In contrast, HUMIDEX values sparsely 9 non-urban LCZs substantially lower indicated better for population. Interestingly, captured increase arising out with presence more vegetation A B) vicinity larger bodies water (LCZ G).
