Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

Trend analysis of hydroclimatological variables in Urmia lake basin using hybrid wavelet Mann–Kendall and Şen tests

, 2018
This paper investigates monthly, seasonal, and annual trends in rainfall, streamflow, temperature, and humidity amounts at Urmia lake (UL) basin and analyzes the interaction between these variables and UL’s water level fluctuation during the 1971–2013 ...

Multi‐Country‐Multi‐City Characterisation of Heat Stress and Exposure in Africa

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
This study provides the first continent‐wide, grid‐specific assessment of heat stress trends in Africa, revealing a sharp rise in multi‐scale extreme heat episodes and shifting population exposure. Findings highlight urgent implications for urban planning and climate adaptation.

Long‐Term Variability and Spatial Differentiation of the Frost‐Free Period in Iceland

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Warming in Iceland (May–September) is expressed as fewer Tmin < 0°C days in the interior and more Tmin > 0°C days along the coasts. ABSTRACT Climate change in subarctic regions leads to significant transformations in thermal conditions; however, the long‐term variability of the frost‐free season (FFS)—and consequently, the growing period—remains poorly

Non‐Stationary Dry‐Spell Hazard Probabilities for Spain

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
This study assesses long‐term changes in dry‐spell hazard probabilities across Spain (1961–2024) using a novel non‐stationary extreme value framework applied to daily precipitation records from a dense observational network. Results show that dry‐spell duration and associated return levels are dominantly stationary, with non‐stationary models providing

Emergence of Subsurface Warming in the Southern Ocean Gateway Between New Zealand and Antarctica

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We analyze temperature variability in the surface and intermediate layers of the Southern Ocean from 1994 to 2025 using a 30‐year summertime record of Expendable Bathythermograph (XBT) measurements collected along the PX36 line across the New Zealand–Antarctica chokepoint of the Antarctic Circumpolar Current (ACC).

Mann-Kendall test application for trend detection in the Cuiabá River-MT

, 2020
Las series de tiempo, también llamadas series históricas o cronológicas, son conjuntos de observaciones recopiladas de manera ordenada a lo largo del tiempo. Los estudios de variables meteorológicas, como el flujo, se han difundido cada vez más debido a los eventos extremos del cambio climático.

Asymmetric Ocean‐Atmosphere Coupling Between Southeast Pacific and Southern Ocean Cooling Through Circulation and Sea‐Ice Changes

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Recent decades have seen persistent sea surface temperature (SST) cooling in the Southeast Pacific (SEP) and Southern Ocean (SO), contrasting with broad ocean warming expected under anthropogenic forcing. Using an interpretable machine‐learning attribution framework applied to multi‐source observations and reanalyses, we focus on monthly SST ...
