ABSTRACT: This study assessed the ways thermal environment is influenced by pre-cooling water employed in wetting porous plates present evaporative cooling systems (ECS). The experiment was performed using two physical models constructed on a distorted and reduced scale, which simulated closed agricultural facilities equipped with ECS made up of cellulose panels. In one model, were wet chilled ...

Background: Climate change is one of the most complex human challenges in future. One consequences climate exposure people to heat stress, especially outdoor environments. The aim this study was model changes trend stress environments coming decades context and global warming. Methods: Wet Bulb Globe Temperature (WBGT) index, Canadian Earth System Model (CanESM2), Statistical Down Scaling (SDSM...

A prototype electronic instrument for the direct measurement of the wet-bulb globe-thermometer index is described. An assessment is made of its accuracy, as compared with W.B.G.T. indices calculated from conventional thermometric data, and a comparison is made between W.B.G.T. values read from the meter and effective or corrected effective temperatures derived from separate thermometric and air...

pavement materials have great impact on heat island control under the urban canyon layer. understanding the properties of pavement materials can help to reduce the heat island effect. introducing the main properties of pavement surfaces affecting sol-air temperature and mean radiant temperature - such as albedo, permeability, conductivity, thickness, emissivity, irradiation and convective air f...

This paper describes the relationship between surface conditions (temperature and humidity) and subsequent rainfall. The focus is on convective storms that are forced and maintained locally due to conditional instability in the vertical distribution of atmospheric temperature. These storms are described using two probabilistic measures: (1) the probability of occurrence of storms given surface ...
