Abstract

Daily data on sand-dust prevalence, precipitation, temperature, and wind speed from 13 national meteorological stations in wind and sand-prone areas of the Hexi Corridor were collected from 2005 to 2023, together with historical data from 1960 to 2020, to identify characteristic spatiotemporal variations in precipitation and temperature during 1–10 days before sand-dust events. The standardized precipitation evapotranspiration indices from January to December were also calculated. The influence of meteorological conditions at different time scales on the dust intensity in this region was then determined. It was found that (1) Sand abundance, the presence of desertified land, and the arid continental climate in the Hexi Corridor contributed significantly to the incidence of sandstorms in China. Due to its abundant sand, high temperatures, and large evaporation capacit-ies, Minqin showed the highest frequency of sandstorms. (2) The severe sandstorms and the high storm frequencies in the Hexi Corridor were found to be associated with warm and dry centers in the region, with the annual number of sandstorm days correlating positively with annual temperatures and negatively with precipitation (correlation coefficients of 0.58 and −0.29, respectively). (3) The wind thresholds of different dust intensities, precipitation, and temperature thresholds during the 1–10 days preceding sand-dust events, and their onset times were obtained,and the levels and regional distribution of drought in the Hexi Corridor during the preceding 1–12 months as well as the relationships among the parameters were assessed.

期刊介绍： The journal Climate Services publishes research with a focus on science-based and user-specific climate information underpinning climate services, ultimately to assist society to adapt to climate change. Climate Services brings science and practice closer together. The journal addresses both researchers in the field of climate service research, and stakeholders and practitioners interested in or already applying climate services. It serves as a means of communication, dialogue and exchange between researchers and stakeholders. Climate services pioneers novel research areas that directly refer to how climate information can be applied in methodologies and tools for adaptation to climate change. It publishes best practice examples, case studies as well as theories, methods and data analysis with a clear connection to climate services. The focus of the published work is often multi-disciplinary, case-specific, tailored to specific sectors and strongly application-oriented. To offer a suitable outlet for such studies, Climate Services journal introduced a new section in the research article type. The research article contains a classical scientific part as well as a section with easily understandable practical implications for policy makers and practitioners. The journal''s focus is on the use and usability of climate information for adaptation purposes underpinning climate services.
