Fig. 2: Trends of surface wind speed, leaf area index (LAI), soil moisture (SOILM), and dust emission flux.
From: Drivers of recent decline in dust activity over East Asia
Linear trends of (a) annual mean surface wind speed (m s−1 decade−1), (c) leaf area index (m2 m−2 decade−1), and (e) soil moisture (m3 m−3 decade−1) during 2001-2017. The trends are shown only in the dust emission regions (mean dust emission flux > 0.001 g m−2 yr−1). Linear trends of dust emission flux (g m−2 yr−1 decade−1) during 2001−2017 due to (b) changes of surface wind speed (Wind), (d) leaf area index (LAI), and (f) soil moisture (SOILM), respectively. The crosses denote the regions where the trends are statistically significant (p < 0.1). The black rectangle denotes the Eastern Sources (35-49 °N, 94−126.5 °E).
