北半球温带、副极地和极地地区大气降水颜色鲜艳的大量尘埃的降落很少被观察到[1-5]。在二十世纪和二十一世纪初的俄罗斯欧洲北部地区，直到2008年3月25日至26日才记录到此类事件。当时，在阿尔汉格尔斯克地区、科米共和国和涅涅茨自治区的部分地区，观察到大气降水为潮湿的雪和雨，导致雪面上冰壳形成沙子和藏红花色。因此，通过详细的矿物学、地球化学、花粉、硅藻和气象调查，确定黄沙的主要来源是哈萨克斯坦西北部的半荒漠和草原地区以及卡尔梅克的伏尔加格勒和阿斯特拉罕地区。
The descent of a large quantity of dust responsible for bright colors of atmospheric precipitation in the temperate, subpolar, and polar zones of the northern hemisphere is rarely observed [1–5]. In the twentieth century and in the beginning of the twenty-first century in the northern part of European Russia, such events had not been registered right up to March 25–26, 2008. At that time in some parts of the Arkhangelsk region, Komi Republic, and Nenets Autonomous Area, atmospheric precipitation as moist snow and rain responsible for sand and saffron colors of ice crust formation on the snow surface was observed. Thus, due to detailed mineralogical, geochemical, pollen, diatom, and meteorological investigations, it was established that the main source of the yellow dust is the semidesert and steppe regions of the Northwest Kazakhstan, and the Volgograd and Astrakhan regions, Kalmykia.
