The occurrence of severe and inclusive dust storms has caused a lot of damage every year in the Persian Gulf region and it has destructive environmental effects in this area. The aim of this study is to investigate the monthly changes in the frequency of dust storms over Khark, Kish and Qeshm islands located in the Persian Gulf region during the 10-year period (2007–2017) using satellite and model observations. The results show that the highest dust frequency was observed over Qeshm Island followed by Kish and Khark Islands. The highest number of dusty days was reported in all three stations in 2008 and most of the dust events occurred in May and July as compared to other months. The average wind speed in these two months (May and July) shows that the wind directions are mostly from northern and northwestern areas. The dust AOD evaluation of eight dust prediction models shows that the models simulated AOD patterns vary differently from each other for a severe dust storm on July 14, 2014 in the study area. Among the eight models, DREAM8-MACC model has a better performance and has good agreement with satellite observations. The analysis showed a high correlation (R = 0.74) between AERONET and DREAM8-MACC model AOD at the observation sites.

每年波斯湾地区都发生严重的包容性沙尘暴，造成了很多破坏，并且对该地区造成了破坏性的环境影响。这项研究的目的是使用卫星和模型观测资料，调查10年期间（2007-2017年）位于波斯湾地区的Khark，Kish和Qeshm岛的沙尘暴频率每月变化。结果表明，在克什姆岛上观测到的扬尘频率最高，其次是基什和哈克岛。据报道，2008年所有三个站点的沙尘暴天数最多，与其他月份相比，大多数沙尘暴事件发生在5月和7月。这两个月（5月和7月）的平均风速表明，风向主要来自北部和西北部。八个尘埃预测模型的尘埃AOD评估显示，对于2014年7月14日在研究区域发生的严重沙尘暴，模拟的AOD模式的模型彼此不同。在这八种模型中，DREAM8-MACC模型具有更好的性能，并且与卫星观测有很好的一致性。分析显示，观测站的AERONET与DREAM8-MACC模型AOD之间具有高度相关性（R = 0.74）。
