This work aims to compare the performance of single‑(SLUCM) and multilayer (BEP-Building effect parameterization) urban canopy models (UCMs) coupled with Weather Research Forecasting model (WRF), along application two heat island (UHI) identification methods. The methods are: (1) “classic method”, based on temperature difference between rural areas; (2) “local method” at each location when land...

An urban heat island (UHI) is a relative measure defined as a metropolitan area that is warmer than the surrounding suburban or rural areas. The UHI nomenclature includes a surface urban heat island (SUHI) definition that describes the land surface temperature (LST) differences between urban and suburban areas. The complexity involved in selecting an urban core and external thermal reference fo...

Urban heat islands (UHI) are one of the unequivocal effects ongoing process climate change: anthropized areas suffer extreme events that affect human perception comfort. This study investigated road pavements as a passive countermeasure by comparing air temperature (AT) and predicted mean vote (PMV) for different surface materials used to pave historical square in Rome, Italy. The software ENVI...

Estimating future temporal patterns of Surface Urban Heat Islands (SUHIs) on multiple time scales is an ongoing research endeavor. Among these scales, estimation next-day SUHIs special significance to urban residents, yet we currently lack a simple but efficient approach for making such estimations. In the present study, propose statistical strategy estimating nighttime SUHIs, based incorporati...

The interaction between urban heat islands (UHIs) and heat waves (HWs) is studied using measurements collected at two towers in the Beijing, China, metropolitan area and an analytical model. Measurements show that 1) the positive interaction betweenUHIs andHWs not only exists at the surface but also persists to higher levels (up to ;70m) and 2) the urban wind speed is enhanced by HWs during day...
