Investigation of drought propagation in South Korea using drought index and conditional probability

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2018
Meteorological drought commonly originates from precipitation deficit and is then propagated to agricultural and hydrological droughts. Since drought impacts are more directly related to agricultural and hydrological systems of human society, it is ...

Groundwater Rise Sustains the World's Largest Alpine Water System Under Global Warming

open access: yesAdvanced Science, EarlyView.
Shallow groundwater depth (SGWD) across the non‐permafrost plains of the Qinghai–Xizang Plateau decreased at averagely 0.02 m year−1, adding 31.44 Gt of freshwater storage from 2000 to 2020 and sustaining ∼53 500 km2 of alpine ecosystems. A vadose‐zone capacity of 426.6 Gt reveals these aquifers as promising reservoirs, highlighting groundwater's ...

Characteristics of Propagation of Meteorological to Hydrological Drought for Lake Baiyangdian in a Changing Environment

open access: yesAtmosphere, 2022
The analysis of drought propagation has garnered mounting attention in the changing global environment. The current studies tend to focus on the propagation characteristics from meteorological to hydrological drought in rivers. Lakes, despite being a key

Rapid Increase in Extreme Hourly Precipitation in Recent Two Decades in the Tibetan Plateau and Its Large‐Scale Drivers

open access: yesGeophysical Research Letters
Although extreme hourly precipitation (EHP) over the Tibetan Plateau (TP) has received growing attention, its spatiotemporal variability and the underlying mechanisms governing regional responses remain unclear.

Do More Open Economies Export Less Diversely in Brazilian Agribusiness?

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper asks whether municipalities with a larger export‐to‐revenue ratio display a more concentrated bundle of exported goods in Brazilian agribusiness. Recent advances in export imputation for Brazilian municipalities allow for an analysis of the concentration profile of each municipality and its association with export openness.

Remote modulation of European blocking on 2022 Pakistan summer extreme rainfall: the bridge role of Tibetan Plateau

open access: yesnpj Climate and Atmospheric Science
In the summer of 2022, extreme rainfall struck Southern Pakistan, causing catastrophic floods and severe damage to both ecosystems and human communities. Previous studies have linked this extreme rainfall to the European blocking high, yet the underlying

Vulnerability of traditional beef sector to drought and the challenges of climate change: The case of Kgatleng District, Botswana [PDF]

open access: yes, 2008
Cattle’s rearing in Botswana is undertaken in two sectors: the communal and commercial. The communal sector is exclusively free range and therefore depends on biomass production. This makes the systems highly susceptible to drought. One strategy that has

Weather Attention in Online Discourse and Price Uncertainty in Agricultural Futures Markets

open access: yesAgribusiness, EarlyView.
ABSTRACT Weather is a central determinant of production risk in agricultural markets, but markets respond not only to weather conditions themselves, but also to how those conditions are noticed, framed, and interpreted in public discourse. In this setting, real‐time online weather discussions may shape price uncertainty by influencing how market ...

A reflectivity factor correction algorithm for X-band phased array radars

open access: yes暴雨灾害, 2023
The difference between reflectivity factors observed by different radars observing the same target affects the performance of the multi-radar mosaic. For X-band radars without beam blocking, this difference is mainly caused by calibration deviation and ...
