This paper investigates the function of windcatchers in dry regions in Middle East and compares them in different fields in two areas including Yazd-Iran, and Egypt. The study examines windcatchers in these areas in terms of cooling system and forms, with different plans, forms, constituent components and decorations.Reassessment of windcatchers in these areas can shed light on these difference...
Understanding the situation, behavior and the nature of sand dunes and also their location, transport and deposition are very important. On the other hand, the importance of sand dunes is due to the impacts that they have on water and soil resources, flora and fauna and human infrastructure. This study, looks at the development patterns of sand dunes in Mesr erg region. In the first part, data ...
Introduction: The present study aimed to investigate the change of air pollutants in 2020 in Qom compared to the same period in 2019 in five scenarios. Materials and Methods: The hourly air quality data was obtained from air quality monitoring stations of Qom Environmental Protection Organization (EPO). The meteorological parameters were obtained from Iranian Meteorological Organization websi...
Rural architecture reflects the integration of architecture with the environment and culture. This kind of relation has been considered as the main factor which brings about diversity in the form of residential architecture in different rural areas. In cold and mountainous climates of Iran, factors such as climate, land type, livelihoods have made differences in architectures. But this fact is ...
sand and dust storms are natural events that occur widely around the world, mostly in dry and bare lands. over thepast decade a large part of iran has been affected by this phenomenon, and tehran has not been excluded from thisevent. therefore, having knowledge of spatiotemporal frequency variations can aid us in future management andstorm trajectory assessment. in this study the synoptic anemo...
The wheat production in midland China is under serious threat by frequent Dry-Hot Wind (DHW) episodes with high temperature, low moisture and specific wind as well as intensive heat transfer and evapotranspiration. The numerical simulations of these episodes are important for monitoring grain yield and estimating agricultural water demand. However, uncertainties still remain despite that enormo...
