Comparing non‐staining methods with Mutvei's solution to visualize growth increments in short‐lived intertidal marine gastropod shells

Limnology and Oceanography: Methods, EarlyView.
Abstract Mutvei's solution is a widely utilized standard staining method for revealing growth increments in biogenic carbonates; however, it is a slightly toxic, destructive approach with varying success across species groups. Therefore, there has been growing interest in finding non‐toxic, less destructive, and straightforward alternative techniques ...

Observed streamflow data shows El Niño–Southern Oscillation increases likelihood of extreme events in South America

Communications Earth & Environment
Understanding how the El Niño–Southern Oscillation influences extreme streamflow events is essential for anticipating water-related risks in South America. Here, we analyse the relationship between this climate phenomenon and the likelihood of floods and

South American streamflow and the extreme phases of the Southern Oscillation [PDF]

, 1995
This study investigates the extent of the affect [sic] of the El Niño/Southern Oscillation on South American streamflow. The response of South American precipitation and temperature to the extreme phases of ENSO (El Niño and La Niña events) is well ...

El Niño variability off Peru during the last 20,000 years [PDF]

, 2005
Here we present a high-resolution marine sediment record from the El Niño region off the coast of Peru spanning the last 20,000 years. Sea surface temperature, photosynthetic pigments, and a lithic proxy for El Niño flood events on the continent are used

Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

People and Nature, EarlyView.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

Meteorological conditions leading to a catastrophic, rain‐induced landslide in Cameroon in October 2019

Quarterly Journal of the Royal Meteorological Society, EarlyView.
October 2019 was characterized by three main multiday wet spells in Bafoussam and Dschang. Our results indicated that wet spells were influenced by a vortex pair near the Gulf of Guinea, a strong Sahara Heat Low located anomalously far east and north, a northward shift of the intertropical discontinuity, an enhancement of the inland penetration of the ...

South Pacific Oscillation contributes to multi-year ENSOs

npj Climate and Atmospheric Science
Multi-year El Niño-Southern Oscillation (ENSO) events, where the warming (El Niño) or cooling (La Niña) extends beyond a single year, have become increasingly prominent in recent decades. Using observations and climate model simulations, we show that the

Windows of opportunity in subseasonal weather regime forecasting: A statistical–dynamical approach

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study explores how the atmospheric state at initialisation creates windows of opportunity for improving week 3 forecasts of weather regime activity. Greenland blocking activity increases following Madden–Julian Oscillation phases 7, 8, and 1 and weak stratospheric polar vortex states, revealing patterns exploitable by statistical models.
