Fig. 4: Relative contribution of driving factors to occurrence probability of 3 types of dust events.
From: Contributions of climatic factors and vegetation cover to the temporal shift in Asian dust events

a–e Change in occurrence probability of each type of dust event averaged from all stations due to each factor. f The relative contribution of each factor to long-term trends in the occurrence probability of dust events. The trend lines were fitted by the Theil–Sen estimator. *p < 0.05; **p < 0.01. LDE light dust events, MDE moderate dust events, SDE severe dust events. Pre-30 precipitation in the previous 30 days.
