In recent years, northeastern Iran, particularly Khorasan Razavi province, has experienced wind erosion and dust storms, although large-scale studies are limited. To assess patterns, sand drift, events, hourly data were analyzed using Fryberger’s method, along with trend analysis through the Mann–Kendall Sen’s slope tests. Additionally, MODIS satellite Google Earth Engine helped identify event frequency spatial patterns. The results show that east (12%) southeast winds (9.6%) most frequent, an average annual speed of 4.39 knots. Sand drift potential (DP = 96, RDP 21.6) indicates movement from to northwest, a multi-directional system (unidirectional index 0.22). AOD amount in north northwest part is more than other locations, 500 events been registered over last two decades. These findings suggest policymakers should monitor these trends mitigate environmental infrastructural damage caused by blowing sand.

This study provides a comprehensive evaluation of dust events over Iran, using synoptic data from 286 meteorological stations. The are classified according to codes as suspended and others (i.e., blowing dust, storms) based on their intensity with horizontal visibility ≤1, 3, 5, 10 km. Severe (visibility ≤ 1 km) (code 06) occurred primarily in the western parts while moderate or severe dominated south eastern thus revealing contrasting spatial distribution regarding type frequency events. Furthermore, distinct seasonality is revealed number events, since maximized SW Iran March July, highly associated Shamal winds, storms east April August. Zabol city, some stations along coast Arabian Sea impacted by this storm throughout year. Trend analysis notable increase during period 1994–2023, particularly part mostly attributed transboundary Mesopotamian plains. large activity 1994–2009 was followed decrease 2010s at many stations, differences were observed trends dust. An inverse correlation between precipitation anomalies observed, years abnormal (e.g., 2019; 138% increase) related substantial occurrence. Over an 11-year period, surface concentrations exceeded annual PM10 threshold 50 µg/m3 more than 800 days, maximum reaching up 1411 µg/m3. highlights urgent need for effective management strategies mitigate impacts air quality public health Iran.

Dust is one of the most important problems human societies in arid and semi-arid areas. This study analyzed rising propagation dust storm occurring from 21 to 23 May 2016 Isfahan province (Central Iran) by using WRF-Chem HYSPLIT models. The was visualized visible imagery coarse-mode aerosol optical depth data satellite sensor data, emission transport were simulated for Central Iran with AFWA GOCART schemes. results show that concentration Sistan Baluchistan Persian Gulf as high 2000 µg/m3, both schemes estimate highest amount emissions central parts eastern part province. PM10 Yazd station used verify model outputs, which showed scheme has a higher correlation coefficient observations (0.62) than scheme. case suggests simulate reasonably good reliability, though further determination enhancement are still required an accurate prediction extents.
