From Rare to Recurrent: Intensifying Hot–Dry Extremes Across Romania

International Journal of Climatology, EarlyView.
Romania has undergone a marked shift toward more frequent and spatially extensive compound hot–dry months since the 1990s, with persistent hotspots in the eastern Moldavian Plateau and the lower Danube–Bărăgan–Black Sea lowlands and comparatively buffered conditions at higher elevations.

Annual and Seasonal Rainfall Variability in Mozambique During the Nineteenth Century

International Journal of Climatology, EarlyView.
This paper presents the first annually and seasonally resolved reconstructions of nineteenth‐century rainfall variability for Mozambique derived from the analysis of extensive documentary evidence. It reveals spatially heterogeneous rainfall patterns with recurrent multi‐year droughts, episodic extreme wet events, and a strong coherence between ...

Revegetation-induced drought propagation shifts prolong hydrological drought recovery on the Loess Plateau, China

Agricultural Water Management
Given the inadequate focus on vegetation’s regulatory role in drought propagation, the neglect of differences among vegetation types in mediating drought cascades, and the lack of attention to hydrological drought recovery dynamics, this study targeted ...

Coping with drought for food security in Tigray, Ethiopia [PDF]

, 2011
Agricultural production in drylands suffers from drought and in sub-Saharan Africa, only about 15% of the terrestrial rainwater is used by plants for food, fodder and fiber.

Compound Meteorological and Hydrological Hot‐Dry and Hot‐Wet Extremes Over Global Land Areas: Spatiotemporal Changes, Attribution, and Drivers

International Journal of Climatology, EarlyView.
The changes in joint return period of compound meteorological hot‐dry (CMHHE) and hot‐wet (CMHWE) and compound hydrological hot‐dry (CHHDE) and hot‐wet (CHHWE) extremes were attributed to changes in associated univariate extremes and their dependence.

Hydrological drought characteristics

In this chapter, you will find an overview of the most used hydrological drought characteristics and their derivation. This includes single low flow indices, such as percentiles from the flow duration curve; drought deficit characteristics derived by the

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Sensitivity of Consecutive‐Dry‐Day Trends to Trace Loss in Matched Precipitation Archives

International Journal of Climatology, EarlyView.
Loss of trace precipitation information can turn valid dry days into missing observations that interrupt consecutive dry day (CDD) spells. Simulating this loss reduced the median cross‐archive CDD trend discrepancy by 88% across 205 matched Spanish station pairs; a separate global experiment converting documented traces to missing observations changed ...

Improving Daily Rainfall Downscaling Over Taiwan's Complex Terrain With Surface‐Wind‐Informed Deep Learning Model

International Journal of Climatology, EarlyView.
An encoder–decoder architecture (EDA) dynamically downscales coarse‐resolution climate fields (0.25°) to high‐resolution outputs (0.05°) over Taiwan, improving the representation of fine‐scale spatial variability and localized extremes by incorporating both rainfall and surface winds to maintain physical consistency.

Method for identifying non-stationary hydrological drought in regions with intense human activities

Journal of Hydrology: Regional Studies
Study region: the middle reaches of the Yellow River Basin (MYRB). Study focus: In regions with intense human activities, the stationarity of runoff sequences was disrupted due to the dual impacts of climate changing and human activities.
