“…Commonly, drought occurs due to an extended period receiving below average rainfall. This is considered a meteorological drought, which progresses into agricultural, hydrological, and socio-economic drought [3]. The general perception is that the UK is not a drought-prone country; however, the UK has experienced frequent occurrence of drought events such as those of the 1970s, 1980s and 1990s, where summer drought events were the outcome of increased variability in climate [4].…”

“…Phân tích MK và TS [14][15][16][17] được ứng dụng trong nhiều lĩnh vực liên quan đến đánh giá xu thế biến đổi và dự tính các giá trị trong một chuỗi dữ liệu thời gian. Trong lĩnh vực Khí tượng và Thủy văn các phân tích này được ứng dụng nhiều trong các nghiên cứu về xu thế biến đổi nhiệt độ, lượng mưa, và hạn hán trên thế giới [18][19][20][21][22][23][24]. Tại Việt Nam, phương pháp được sử dụng ngày càng phổ biến trong các nghiên cứu về xu thế biến đổi các yếu tố liên quan đến Khí tượng và Thủy văn [25][26][27][28].…”

“…Gebremeskel et al (2020) analysed the long-term drought variability over the Greater Horn of Africa using SPEI and revealed that Somalia, Ethiopia and Kenya experienced more severe drought. In the southwest part of Africa, Byakatonda et al (2018) used SPI and SPEI methods to study the semi-arid drought severity over Botswana and found that drought areas with 96% of confidence at 12 monthly timescales. The Mann-Kendall Z-statistic and Sen's slope estimator were employed to analyze the monotonic changes of the drought (Byakatonda et al 2018).…”
