the kashan erg is one of the most important sand dune complexes in iran. being affected by wind erosion, theerg's borderlands face numerous problems as a result of sand movement. to evaluate the risk of sands moving intoresidential areas near the kashan erg, anemometry data from synoptic stations located in kashan, ardestan, meimeh,naeen, and qom were collected and analyzed to calculate the san...
erosion by wind is one of the most important factors in desert environment. prevailing winds can shift sand dunes and affect their accumulation. also, wind regime determines the direction of sand dune mobility. the aim of this research was to investigate sand drift potential using sand movement models. for this research, wind data between 1986 and 2005 from the meteorological station of yazd we...
in order to recognize the wind erosion situation of a region, the survey of its windiness is not sufficient and the physical characteristics of earth are of importance too. in fact, the outbreak of dust storms in a region is due to the sensitivity of earth and domination of wind in that region. in this investigation we have tried to find a way for determining the regions in which a dust storm i...

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 purpose of this research is to analyze anemometer data to study the wind regime in Kashan and to investigate the role of different land uses in sand storms. Therefore, anemometer data obtained from synoptic station of Kashan were analyzed during a 40-year period (1966-2005) using different methods. Seasonal and annual wind roses and storm roses for different lands were created using WRPlot ...
Introduction: Dust storm is one of the air pollutants in desert areas that have damaging effects on environmental ecosystems. This phenomenon usually happens when severe winds occur in arid areas which are accompanied by the ascent of dust particles to the upper layers of the atmosphere. HYSPLIT model can assist in detecting the path of dust entering the stations. In addition, synoptic patterns...
Hurricane Sandy in late October 2012 drove before it a storm surge that rose to 4.28 meters above mean lower low water at The Battery in lower Manhattan, and flooded the Hugh L. Carey automobile tunnel between Brooklyn and The Battery. This study examines the surge event in New York Harbor using the Weather Research and Forecasting (WRF) atmospheric model and the Coupled-Ocean-Atmosphere-Wave- ...
