Trends in source contributions of large dust events in Central East Asia (2000-2023) (IMAGE)
Caption
This figure summarizes the changes in dust emissions and source contributions of each large dust event across Central East Asia from 2000 to 2023. Bar graph (a) shows the annual average contribution rates of northern China and Mongolia, revealing a gradual decline in China’s contribution and a steady rise in Mongolia’s. Graph (b) presents total dust emissions from 136 large dust events, which decreased through the 2000s but increased sharply after 2020. Graph (c) illustrates the source contribution for each event, with blue bars indicating Mongolia and red bars indicating northern China. Together, the data highlight a shift in major dust sources and the growing influence of Mongolia in recent years.
