This research was conducted to identify the dust storms in the Midwest of Iran from June 16 to 19, 2015. To investigate the synoptic conditions of the causes of this phenomenon, the ECMWF has an array of 0.125 degrees, including geopotential, omega, and sea level pressure, orbital and meridian components of the wind, specific humidity Soil moisture was applied to a depth of 10 cm. Similarly, fo...
Background: The phenomenon of dust is a serious environmental problem in dry and semi dry regions. It has a destructive effect for the residents of such regions. Over two-thirds of Iran is in areas of dry and semi-dry climate conditions. Methods: In this research, dust fall measurements were taken in 41 stations across Yazd city using a marble dust collector (MDCO) located in diffe...
Dust phenomenon is the One of the most important hazards in the dry and semi-arid region. The occurrence of this phenomenon is accompanied by many physical and financial losses. In this research, was studied the characteristic of land use and geomorphology dust source in Khorasan Razavi Province. At first, 65 soil dust sources were identified for the time period (2005-2016) by using the dust en...
abstract: the dust is one of the weather phenomena that have negative environmental effects and consequences. the central city of ahvaz in khuzestan province is one of cities that in every year witnessed the dust in its environment. in this study, after determining that the dust phenomena data are abnormal, using the sen's nonparametric model been proceed to modeling of changes and survey ...
mineral dust can directly affect the solar and terrestrial radiation in both visible and infrared (ir) spectral regions through scattering and absorption processes. due to specific optical properties of dust particles, satellite observed radiances carry the spectral signatures of dust particles that are different from molecular, cloud, and underlying surface. based on these differences, various...
Effect of Simulated Dust Storm on some Bio-chemical features of Persian Oak (Quercus brantii Lindl.)
Extended abstract 1- Introduction Dust storm is a hazardous natural event affecting all creatures. (1). Due to the global warming drought, reduction in precipitation, and mismanagement in the water by humankind, the negative effects of this calamity were more observed (2). With increasing the wind speed, and based on the size of dust particles, land topography, soil humidity, vegetation cover...
limestone, exploited near bielawy, a town located in the kujawsko-pomorskie province ofpoland, is the main raw material in the production process in a cement plant. the dust emitted by the factory is of alkaline ph and contains such heavy metals as: cadmium (cd), lead (pb), chromium (cr) and nickel (ni). the research aims at assessing the influence of cement dust on the total content and bioava...
