“…West and SW Iran are mainly influenced by dust storms originated from deserts in Syria, Iraq, Saudi Arabia, and Kuwait [6][7][8]13,14]. More than 90 percent of dust particles originate from external sources, whereas the contribution of internal dust sources is less than 8 percent in this area [15]. Also, Ahvaz (in SW Iran) is one of the dustiest cities in the world and the second-highest PM 10 was reported from the city (5338 µg/m 3 ) in June 2010 across the Middle East area [16].…”

The dust storms with local and non-local dust sources mostly affect Khuzestan province in southwest (SW) Iran. In this study, the role of the low-level jet in the activation of the internal dust events in SW Iran during two severe dust cases was investigated. For this purpose, the fifth-generation ECMWF reanalysis for the global climate and weather (ERA5) data was used to identify the synoptic patterns and the low-level jet (LLJ) characteristics in the study area. Furthermore, the images of the moderate resolution imaging spectroradiometer (MODIS) sensor, the outputs of the hybrid single-particle Lagrangian integrated trajectory (HYSPLIT) model, and a weather research and forecasting model coupled with chemistry (WRF-Chem) were used to investigate the propagation and transport of the dust particles. The results of the synoptic analysis in both dust cases show the simultaneous occurrence of the divergence zone associated with cyclonic curvature in the subtropical jet stream (STJ) at 300 hPa, causing convergence at 925 hPa, upward motion, and the development of low surface pressure in SW Iran. Examining the vertical wind profile shows the existence of the maximum horizontal wind speeds of 975 to 875 hPa, along with the positive and negative shear below and above it, respectively, which emphasizes the existence of the LLJ and its role in local dust emission. The results of the comparison between the satellite images, WRF-Chem, and HYSPLIT model outputs show the formation and transportation of dust particles from the inner regions of Khuzestan in SW Iran. The horizontal dust surface distribution, vertical raised dust mass, and kinetic energy transfers are well simulated by the WRF-Chem model when LLJ broke at 09:00 to 12:00 UTC. The most important finding of this research is that, for the first time, the role of low-level jet is investigated in the activation of internal dust events in SW Iran.

PurposeThe purpose of this article is to assess climate change impacts on four earthen heritage (EH) sites, highlighting their vulnerability and the need for an integrated approach that considers physical, social and cultural factors.Design/methodology/approachThe study uses a systematic approach to assess climate change impacts on earthen heritage sites. A literature review informed the development of a conceptual model based on climate change risk guidelines and methodologies. The model evaluates site-specific hazards through quantitative and qualitative assessments, considering exposure, sensitivity and adaptive capacity. Vulnerability is calculated using a formula that categorizes it into five levels. Data collection included meteorological analysis, field observations and interviews with local experts.FindingsFindings indicate that climate change has significant consequences for earthen heritage sites, including erosion, structural deterioration and loss of cultural value. The regions of Sistan, Yazd, Persepolis and Tchogha Zanbil are particularly vulnerable due to their specific climatic conditions. Key threats include changes in precipitation patterns, extreme weather events, rising temperatures and water scarcity. Socioeconomic factors like limited conservation resources and inadequate stakeholder communication exacerbate these vulnerabilities. The study highlights the need for interdisciplinary collaboration, effective governance and community engagement to develop comprehensive climate change adaptation strategies.Originality/valueThe article’s originality lies in its systematic assessment of climate change impacts on earthen heritage sites, offering a novel framework that integrates interdisciplinary approaches and site-specific factors.
