Abstract
Problems of modern climate change and assessment of their consequences IPCC (2021-2023) according to the latest assessment reports, there is an increase in dangerous weather phenomena that cause significant social and economic damage in various regions of the Earth. In this article, various climatic factors affecting the state of dust storm formation associated with modern climate change were studied. It was established that the longest (72 hours) duration of dust storms at the Aral Sea station in the southern region of Kazakhstan in the period from 2005 to 2022 was recorded in May 2018. The values of meteoparameters at that time, that is, its dependence on weather conditions, quantitative indicators of solar activity (Wolf number), bioclimatic indicators, as well as the conditions of macrocirculation formation, were considered, and it turned out that there was an important correlation relationship between the number of days when dust storms were most observed and the Wolf number (r=1.00), Wangenheim-GIRs circulation forms, including the e Form (r=0.49), El- Niño indices (r=0.47 as a result of the analysis, it was determined that the prolonged Obser ation of dust storms was associated with the north-western cold front.
