Yangtze River Basin, China As agricultural drought originates from meteorological drought, exploring the propagation to is an important step in providing early warning of drought. In this study, Standardized Precipitation Index (SPI) and Improved Soil Moisture Anomaly Percentage (ISMAPI) were adopted indicate droughts, respectively. The time was identified, probabilistic linkages between two types investigated using copula function Bayesian network. average Basin (YRB) 48 d. times summer autumn are shorter than those spring winter. occurrence probability more serious gradually increases with intensity. Agricultural events matched proposed event-matching method. YRB, approximately 72.4% may translate into events. Generally, event that has same category as given most likely occur. Regional differences be related variations climatic conditions across regions.

The Yiluo River Basin (YLRB), China Understanding the alterations in drought propagation under evolving environmental conditions is crucial for efficient management of water resources. In this study, 'simulation-observation' comparison method was employed to analyze distinct periods: baseline, simulated, and disturbed periods. This facilitated quantification impact climate change human activities on characteristics, such as response time Standardized Streamflow Index (SSI) Precipitation (SPI) threshold. times SSI SPI has been prolonged at monthly seasonal scales due change, while it reduced annual scale. lengthening only evident longer temporal scales. Human have contributed higher thresholds severe extreme droughts scales, increasing probability droughts. Meanwhile, partially offset negative impacts activities. However, scale, main cause thresholds. conclusions drawn from research provide valuable insights development policies aimed managing a changing environment.

Abstract Meteorological and soil drought is disastrous to natural social systems. It expected that the occurrence of meteorological compound events will become more frequent extreme in future. The propagation process plays an essential role drought. However, not clear, especially quantification characteristic rarely realized. This study constructs intensity index (DIP) duration (DDP), then puts forward partition China. Furthermore, this preliminarily discussed driving factors relationship between land‐atmosphere interaction main (arid type area, peer‐to‐peer humid area). results show DDP DIP are significantly negatively correlated China from 1981 2020. From southeast northwest, gradually increased decreased. We further concluded 68% regions with similar (peer‐to‐peer area) concentrated semiarid dry subhumid, which exactly area strong interaction. In all land use types, grasslands most prone reveals law mechanism provides a new idea attempt clarify process.

Drought is one of the most complex natural phenomena affecting life and livelihood people, especially in current time human-induced climate change. This research employs ground-based observations to assess recent spatiotemporal characteristics meteorological drought events over Rwanda. The examined based on Standardized Precipitation Evapotranspiration Index (SPEI) (SPI) at seasonal annual scales from 1981 2020. Man–Kendal test was used evaluate trends rainfall, temperature, SPEI values scale during March May (MAM) October December (OND) seasons. analysis revealed nonsignificant (8.4 mm/decade), MAM (−3.4 OND (4.5 mm/decade) while an apparent significant increasing trend surface air temperature obtained (0.19 °C/decade), (0.2 (0.23 °C/decade) slices. Overall, indicated that country more prone moderate than severe extreme However, intensity, duration, frequency differ spatially among findings this study inform policy decision-makers past experienced behavior, which can serve as a baseline for future mitigation adaptation plans.
