Pink shade indicates drought period. Orange shades indicate the overshoot periods, with hatched ones indicate the overshoot components identified by our algorithm. Take this summer drought event as an example, among the four lagged effects, previous-month 2—3 shows a strong negative sensitivity and a negative contribution during the drought period, therefore it is considered as an overshoot component, its contribution also dominates all the lagged effects during the drought, this drought event is therefore considered as an overshoot drought event.
Subseasonal indicates lagged effect from previous 2—3 months, seasonal indicates previous 4—6 months, intra-annual for previous 7—12 and interannual for previous 13—24 months. Insets show the histograms of the anomalies. Insets show the histogram of the development speed. Both soil moisture datasets were de-seasonalized and detrended first so that we only focus on the soil moisture anomalies. Soil moisture were integrated for top 1m for ERA5 and 0.
The pixel-level comparisons were only conducted when at least two overshoot and two non-overshoot drought events happened during the study period. The insets show the histogram of the differences, with negative values indicating average soil moisture declining speed is greater more negative for overshoot drought than non-overshoot drought.
Drought development time is defined as the monotonical decrease period from local maximum to local minimum in the de-seasonalized detrended NDVI anomalies. Inset in b show the histogram of the differences.
Overshoot droughts, compared to the non-overshoot ones, usually have weaker drought stress bottom panel , but relatively stronger impact on vegetation upper panel. Insets show the histogram of differences in anomalies. Insets show the histogram of the coefficients. Reprints and Permissions. Zhang, Y.

According to Kenya Metrological Department KMD , several parts of the country will generally remain dry and sunny during the month of September Counties in Northwestern Region including Turkana, West Pokot and Samburu are likely to experience sunny and dry weather conditions throughout the month.
However, areas bordering Uganda and Southern Sudan are likely to experience occasional rainfall during the first two weeks of the month.
