Bias Correction of ERA5 Temperature Across Five Topoclimatic Clusters: A Comparative Evaluation of Four Methods

International Journal of Climatology, EarlyView.
ERA5 near‐surface temperature over South America exhibits systematic cold biases in daily maximum temperature and warm biases in daily minimum temperature. To address the continent's strong climatic and topographic heterogeneity, South America was partitioned into five topoclimatic clusters, and four bias‐correction approaches were evaluated. The Multi‐

Inventory Optimization Model of Biomass Power Plant Considering Multiple Uncertainties

Zhongguo dianli
The formulation of inventory optimization strategies for biomass power plants is the basis for ensuring regional power supply. However, the seasonality and demand uncertainty of biofuels have brought great challenges to inventory optimization.

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

International Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

Seasonal Hydrological Variability Shapes Protistan Community Diversity and Assembly in a Subtropical River as Revealed by Environmental DNA Metabarcoding

Diversity
Hydrological seasonality is a major driver of microbial community dynamics in river ecosystems, yet how seasonal flow regimes regulate protistan diversity, community assembly, and functional organization remains poorly understood.

A spatio-temporal weather generator for the temperature over France [PDF]

Advances in Statistical Climatology, Meteorology and Oceanography
Stochastic weather generators are efficient statistical models producing synthetic weather series by replicating key statistical properties without the computational cost of physical models. However, for applications requiring temperature simulation over

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.

Wavelet-Based Test for Time Series Non-Stationary [PDF]

Statistika: Statistics and Economy Journal, 2015
In the present paper, we propose a wavelet-based hypothesis test for second-order stationarity in a Gaussian time series without any deterministic components or seasonality.

‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

Journal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...

Seasonality of birth in nineteenth and twentieth century Austria: steps toward a unified theory of human reproductive seasonality [PDF]

We present an analysis of birth seasonality in nine geographical regions within Austria for two time periods, 1881-1912 and 1947-1959. In the early period, geography, climate, and agricultural patterns were related to birth seasonality. By the later time

Viability analysis and the importance of fine‐scale variables influencing roadkills of a toad population

The Journal of Wildlife Management, EarlyView.
Fine‐scale population variables better explain roadkill patterns in natterjack toads (Epidalea calamita) than habitat proxies, with mortality driven mainly by local abundance, reduced by roadside embankments, and decreasing as the season advanced. Despite high roadkills, population viability analyses indicate no immediate extinction risk under current ...
