Study finds cause for shift in Middle East dust activities
The Middle East, as the world’s second-largest dust source, contributes to over 10% of the global dust emissions, with a pronounced peak during the summer season. Transported dust particles influence numerous densely populated regions, spanning from North America to South Asia, and have adverse effects on transportation, health, agriculture and the environment.
Analysis of multi-source data indicates that over the past two decades, summer dust activity in the Middle East has undergone a significant trend shift. Around 2010, the trend transitioned from a notable increase to a marked decline. The underlying causes for this shift nonetheless remained unclear. Consequently, uncovering the factors behind the trend shift and investigating the specific impact mechanisms are of great importance for the study of global climate and environmental change.
