“…Using the NOAA HYbrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT_4) model (Draxler and Hess, 1998;Stein et al, 2015) and NCEP Global Forecasting System (GFS0.5) gridded meteorological data with 0.5º × 0.5º resolution from the NOAA archive (ftp.arl.noaa.gov/pub/archives/gdas0p5), the 3-day backward trajectories of air particles arriving at levels 1/5H 0 , 2/5H 0 , 3/5H 0 , 4/5H 0 and H 0 (where H 0 is the height of the upper boundary of the mixed layer above the station at the moment of PM 10 measurement) were calculated for the five studied weather stations (Urmia, Tabriz, Bokan, Sardasht, and Khoy) in the Urmia Lake region, using the algorithm described by Shukurov et al (2018). The backward trajectories started at the indicated altitudes every hour in the interval from 15:00 UTC on April 23, 2017 to 09:00 UTC on April 26, 2017.…”

Dried lake beds are one of the largest sources of dust in the world, causing environmental problems in the surrounding areas. In this study, the desiccated Urmia Lake was the primary source of dust for all nearby synoptic stations during the April 24-25, 2017 dust episode. Synoptic analysis revealed that the heavy dust storm was triggered by a strong Black Sea cyclone and a low-pressure system over central Iraq in conjunction with a vast high-pressure system. HYSPLIT-based trajectory analysis showed that high PM10 recorded over the Urmia Lake region on April 23-26, 2017, influenced western Azerbaijan, the south of the Caspian Sea, southwestern Kazakhstan, northwestern Uzbekistan, and western Turkmenistan. The dustiest air masses (PM10 > 400 µg m–3) affected the south of the Caspian Sea and western Azerbaijan. Furthermore, the WRF-Chem model was run to evaluate the spatial distribution of dust particles in the study region. The vertical profile revealed that the simulated dust concentration ascended to 5 km from the lake. The WRF-Chem dust schemes accurately simulated dust propagation and the vertical dust profile over Urmia Lake; however, the AFWA and GOCART dust schemes showed that PM10 fluctuating changes were earlier than the measured surface PM10 at five stations around Urmia Lake on April 23-26, 2017. Furthermore, the maximum amount anticipated by the model simulation was 12 h earlier than the maximum surface mass concentration of measured PM10 at the stations throughout the period.
