Atmospheric rivers (ARs) play an important role in the water cycle and destructive phenomena such as floods and storms. Thus, here the origin, structure, and pathway of ARs in the world were investigated considering the importance of the issue. To this end, the daily wind vector and jet stream data of the ERA-Interim were obtained with 0.25° × 0.25° spatial resolution for 1995–2019. Satellite images of Moderate Resolution Imaging Spectroradiometer (MODIS), Global Precipitation Measurement (GPM), and Geostationary Operational Environmental Satellite (GEOS) Water Vapor were used to examine the amount of precipitation caused by ARs. Also, graphical images were produced to study the origin, pathway, and expansion of ARs. The results indicated that jet streams play a major role in the genesis, direction, and pathway of ARs. Also, high-pressure (low-pressure) centers have a substantial role in the expansion (destination) of ARs. Regions such as west of the USA, west of southern headland of South America, northwest of Europe, the path of northeast Saudi Arabia to northeast Iran, Australia, and the distance between Japan and the east coast of Russia were the most affected regions of precipitation due to ARs. According to the results, there were seven major sources of ARs in the world, of which the most important one was located in southeast Asia. Regarding monthly distribution, January, September, and October had the highest occurrence of ARs. There was a minor difference in the number of ARs in two hemispheres. Only in the southern hemisphere did the ARs have a longer longitude. Investigating the number of occurrences of ARs indicated that in the highest state, three to four ARs were observed in the world simultaneously. Also, more than 90% of the ARs moved through the oceans.

大气河流（AR）在水循环和洪水和暴风雨等破坏性现象中起着重要作用。因此，这里考虑到该问题的重要性，对世界范围内增强现实的起源，结构和途径进行了研究。为此，获得了1995-2019年ERA-Interim的日风矢量和射流数据，其空间分辨率为0.25°×0.25°。中分辨率成像光谱仪（MODIS），全球降水量测量（GPM）和地球静止运行环境卫星（GEOS）水蒸气的卫星图像用于检查由AR引起的降水量。此外，还制作了图形图像来研究AR的起源，途径和扩展。结果表明，射流在AR的发生，方向和途径中起着重要作用。也，高压（低压）中心在AR的扩展（目的地）中起着重要作用。受降水影响最严重的地区包括美国西部，南美南部岬角以西，欧洲西北部，沙特阿拉伯东北部到伊朗东北部的道路，澳大利亚和日本与俄罗斯东海岸之间的距离。由于AR。根据结果​​，世界上有七种主要的AR来源，其中最重要的是东南亚。关于每月分发，1月，9月和10月的AR发生率最高。两个半球的AR数量存在细微差异。仅在南半球，AR的经度更长。调查AR的发生次数表明，在最高状态下，全世界同时观察到三到四个AR。另外，超过90％的AR穿越海洋。
