Drought hazard transferability from meteorological to hydrological propagation [PDF]

Journal of Hydrology, 2020
Abstract As a major weather-driven disaster, drought can be assessed from meteorological to hydrological aspects. Although the propagation from meteorological to hydrological droughts has received lots of attention in recent years, the hazard transferability in such a propagation process has been less investigated.

Initial soil moisture conditions dominate variation in event-scale propagation time from meteorological to agricultural drought

Agricultural Water Management
Agricultural drought, typically triggered by meteorological drought, poses a significant threat to crop production and regional water resources. Understanding the propagation from meteorological to agricultural drought is therefore crucial for improving ...

Formative drought rate to quantify propagation from meteorological to hydrological drought

Hydrological Processes
AbstractIn this study, we propose a probabilistic metric, the formative drought rate (FDR), to quantify drought propagation. It is the probability that a meteorological drought in precipitation forms a hydrological drought in streamflow. Drought events were identified based on the standardized precipitation index and streamflow drought index ...

Attribution mechanism of drought propagation time with changes in climate and underlying surface

Journal of Hydrology: Regional Studies
Study region: Thirteen catchment regions of the Yellow River basin, located in northern China. Study focus: Drought is a natural phenomenon characterized by a water deficiency that impacts various aspects of the hydrological cycle.

From Natural Discovery to AI‐Guided Design: A Curated Collection of Compact Enhancers for Crop Engineering

Advanced Science, EarlyView.
ABSTRACT Precise transgene‐free gene upregulation remains a challenge in crop biotechnology, as conventional enhancers often exceed CRISPR‐mediated knock‐in size constraints and face regulatory hurdles. Here we establish a foundational cross‐species resource of compact transcriptional enhancers developed via STEM‐seq, a high‐throughput screening ...

Pomegranate transplant stress can be ameliorated by rhizophagus intraradices under nursery management [PDF]

, 2018
Arbuscular mycorrhizal fungi (AMF) establish an obligate mutualistic symbiosis with many plant species, increasing the uptake of phosphorous and other low-mobile nutrients by roots.

Compartmentalized Homeostasis Drives High Bamboo Forest Productivity under Nutrient Imbalance

Advanced Science, EarlyView.
This study reveals how Moso bamboo achieves high productivity despite nutrient‐poor soils. It employs a unique strategy, maintaining strict nutrient balance in its leaves while using woody tissues as flexible storage reservoirs. This compartmentalized mechanism buffers the plant from soil phosphorus limitation and microbial competition, resolving the ...

Mechanisms of meteorological drought propagation to agricultural drought in China: insights from causality chain

npj Natural Hazards
Previous studies have overlooked the nonlinear dependency of drought propagation, limiting our understanding of its mechanisms. By establishing a causality chain, this study identifies the nonlinear propagation pathways of meteorological drought to ...
