Diversity, transfer potential, and transcriptional activity of virus‐carried antibiotic resistance genes in global estuaries

iMetaOmics, EarlyView.
Estuaries are vital hotspots for antibiotic resistance genes (ARGs) due to substantial antibiotic pollution. Although viruses have been proposed as key reservoirs and important disseminators of ARGs in environments, their contribution to the estuarine antibiotic resistome remains largely unknown.

A Comparative Study on the Irrigation Suitability of Kerala's Rivers Using Fuzzy AHP and Conventional Methods

Irrigation and Drainage, EarlyView.
ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.

Understanding spring forecast El Niño false alarms in the North American Multi-Model Ensemble

npj Climate and Atmospheric Science
El Niño is responsible for the largest part of the seasonal-to-interannual climate variability, so forecasting El Niño events correctly is important. However, forecasting El Niño events during boreal spring remains challenging.

Forecasting Natural Gas Prices in Real Time

Journal of Applied Econometrics, EarlyView.
ABSTRACT This paper provides a comprehensive analysis of the forecastability of the real price of natural gas in the United States at the monthly frequency considering a universe of models that differ in complexity and economic content. We find that considerable reductions in mean‐squared prediction error relative to a no‐change benchmark can be ...

Correcting Breaks in Temperature and Humidity Observations: Implications for Climate Variability Analysis in Austria

International Journal of Climatology, EarlyView.
A 2‐h shift in the timing of evening observations in 1971 resulted in a discontinuity in the estimation of daily means of air temperature and humidity across all climate stations in Austria. This study employs hourly observations to, for the first time, comprehensively quantify and correct this break.

Synchronisation of Extreme Precipitation and Sea Surface Temperature Events in the Northern Hemisphere: A Complex Network Approach

International Journal of Climatology, EarlyView.
Using complex network theory and event synchronisation, we find distinct spatiotemporal structures of extreme precipitation and sea surface temperature events across the Northern Hemisphere. Our results show strong local and long‐range connectivity in terrestrial extremes, driven by atmospheric dynamics, contrasting with more localised marine extremes ...

The Halloween Indicator is More a Treat than a Trick [PDF]

, 2017
This paper uses stock market returns (2007-2015) and confirms the existence of Halloween effect anomaly after the 2008 financial crisis. Findings suggest that the Halloween effect can still be observed in 34 out of the 35 countries.

Maritime Behaviour Anomaly Detection with Seasonal Context

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Abstract. Monitoring maritime traffic has become an important task for ensuring the safety of vessels, as well as the goods, and persons that they may be transporting. An active area of research is the modelling of expected normal vessel behaviour so as to detect subsequent anomalies in new data.

A Continental United States Climatology of Precipitation Whiplash Using a New Event‐Based Definition

International Journal of Climatology, EarlyView.
Precipitation whiplash events have been increasingly studied over the recent decade, however, no studies have considered the spatial coherence of grid points in their examination. Therefore, we developed an algorithm that defines spatially coherent precipitation whiplash events on the subseasonal‐to‐seasonal timescale between 1915 and 2020 which can be

Large-scale forcing of principal near-surface wind speed variability patterns in the Arctic since 1979

Environmental Research Letters
The ERA5 reanalysis dataset is used to characterize the principal patterns of annual and seasonal near-surface wind speeds in the Arctic from 1979 to 2023 by the empirical orthogonal function (EOF) method, together with their relationship with large ...
