Assessment of dust activity and dust-plume pathways over Jazmurian Basin, southeast Iran

Dust storms in Iran - Distribution, causes, frequencies and impacts

Dust is a common weather phenomenon in the Arabian Gulf, which has severely affected economy and health. Sand and dust storms (SDS) trajectories in the Arabian Gulf were temporally and spatially monitored from March 2000 to March 2017. Eight major SDS trajectories were detected from satellite images. The dust storms trajectories were categorized according to shape and size into three main types with 12 subtypes in the region. The annual transported dust amount into the Arabian Gulf was estimated by 89.1 million metric tons, which is about 10,330 metric tons per cubic kilometer of water volume. In comparison to other seas and oceans, the amount of dust deposited into the Arabian Gulf water body volume is the highest. Dust deposited in the coastal regions within the Arabian Gulf are originated from Mesopotamian Flood Plain (MFP), Ahwaz (HZ), Ahwar (HR) and Baluchistan Desert (BSH) and characterized by physical parameters and composition. Such physical characterization of the trajectories of SDS, and of the properties of particles transported in the Arabian Gulf can be helpful to assess and mitigate the environmental impact of future similar events.

沙和灰尘暴风雨(SDS ) 是在干旱、半干旱的区域的普通现象。在最近的年里， SDS 频率和紧张在伊朗显著地增加了。关于 SDS 来源的研究为理解灰尘产生的机制并且估计它的社会经济、环境的影响是重要的。在这篇论文，我们开发了一条新途径用九相关数据集的联合在伊朗识别 SDS 来源区域，也就是干旱事件，温度， 降水，沙的土壤的地点， SDS 频率，导致人的土壤降级( HISD )，人的影响索引( HII )，雨使用效率(后悔)和网主要生产率( NPP )损失。为了识别 SDS，采购区域，我们第一用兰伯特包括层设计在一致标准下面使这些数据集正常化保角的圆锥形的设计，到光栅的从 shapefile 的数据变换，有从 0 ～ 1 的数据范围的 Min 最大正规化，和由 Kriging 和图象采样(1 km 的分辨率) 的数据插值。在那以后，为 SDS 来源的可能性的 20 张地图通过在平均重量分配标准，每个项目同等地在获得了重量下面覆盖多重数据集被产生。在 20 张地图，越高分数，越多可能一个特定的区域能被认为是 SDS 来源区域。例外主要来自大城市，象德黑兰和伊斯法罕一样。作为结果，最后的 SDS 来源区域被畴划，并且 Al-Howizeh/Al-Azim 沼泽地和 Sistan 盆在伊朗作为主要 SDS 来源区域被识别。在 Al-Howizeh/Al-Azim 沼泽地的 SDS 来源区域仍然不停地膨胀。另外， Al-Howizeh/Al-Azim 沼泽地现在由于自然、导致人的因素正在承受快速的陆地降级并且在不久的将来可能完全消失。Sistan 盆也表明土壤降级和风侵蚀的影响。与适当紧张，持续时间，风速度和灰尘暴风雨的高度，从这个区域高举的沙粒子可能发展成极端灰尘暴风雨，特别在夏天期间。
