Fig. 4: Uncertainty and sensitivity analysis for the forecasted TC displacement in Fiji at different forecast lead time.

a Probability distribution of the impact forecast at different forecast lead times ranging from 3.5 days to 0 days from the landfall of TC Yasa at Fiji, with the black dashed line indicating the number of reported displacement from IDMC and the red dashed line the mean forecasted displacement56. b First-order sensitivity indices of the different uncertainty parameters for the total number of displaced people at different forecast lead times. The error bars represent the 95th percentile confidence interval for each index56.
