英文摘要	Atmospheric rivers (ARs), as narrow, dense water vapour paths, play a major role in transferring large volumes of atmospheric humidity compared to their surrounding areas. Accordingly, ARs have significant effects on the atmospheric water cycle and climatic conditions. They are more remarkable in arid and semi-arid regions due to the priority of water resources management and weather extreme effects. This study identified ARs entering Iran as well as their movement paths and synoptic factors affecting their determination. To this end, integrated water vapour transport data was applied to identify ARs for 2007-2018 (November to April). In general, 364 AR events were identified. The results showed that approximately 52% of ARs were directly originated from the Gulf of Aden and the Red Sea. It was also observed that ARs entered Iran from different paths. By classifying entry paths in terms of location and after conducting synoptic analysis for each path, it was found that the westward or eastward displacement of the Arabian subtropical anticyclone (ASA) and along with the extension pattern of Mediterranean trough was highly important in determining AR paths in the region. Moreover, about 67% of ARs entered the country from south and southwest, respectively, and the highest frequency was in January followed by March.
