Trends in Crop Reference Evapotranspiration and Climatological Variables Across Ceará State – Brazil

Revista Brasileira de Meteorologia
Irrigation has a substantial share in total world water demand. At the global level, the withdrawal ratio for agriculture is 69 percent. Irrigation is necessary to compensate evapotranspiration (ET) deficit due to insufficient precipitation.

Multi‐Timescale Drought Evolution in Greece (1960–2022) From Station‐Based SPI and SPEI

International Journal of Climatology, EarlyView.
Using homogenized data from 67 HNMS stations in Greece (1960–2022), we calculated SPI and SPEI at 1–12‐month scales to characterize meteorological to hydrological drought. We quantified the network‐based spatial extent of drought, compared SPI and SPEI drought signals, and tested changes with autocorrelation‐robust Mann–Kendall trends and Pettitt ...

Station‐Based Assessment of Sub‐Seasonal Climate Trends in the Tyrolean Alps (Austria)

International Journal of Climatology, EarlyView.
In this study, we quantify the magnitude and significance of sub‐seasonal trends in the Tyrolean Alps (Austria) by collecting, processing and analysing meteorological observations from a dense network of climate stations. Our analysis indicates a warming rate of 0.43°C/dec over 1964–2023, greater sub‐seasonal trend variability when the analysis window ...

Trend analysis by Mann-Kendall test for precipitation and temperature for thirteen districts of Uttarakhand

Journal of Agrometeorology, 2014
The present study is mainly concerned with the changing trends of rainfall and temperature of all the thirteen districts of the state Uttarakhand. The state lies on the southern slope of the Himalayan range and the climate and vegetation vary greatly with elevation, from the glaciers at the highest elevations to subtropical forests at lower elevations.

Spatiotemporal Characteristics and Synoptic Patterns of Dry‐Hot Winds (Sukhoviys) in Ukraine

International Journal of Climatology, EarlyView.
This study analyses dry‐hot winds, or sukhoviys, a recurrent phenomenon during the warm season across Ukraine that contributes to rapid moisture loss from soil and vegetation. The activity of sukhoviy events was assessed using the introduced Sukhoviy Station Index, accounting for their meteorological characteristics and frequency of occurrence.

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.

Spatiotemporal Evolution of Regional Heavy Rainfall Events in Guangdong, South China: Intensification and Expansion Since the Early 1990s

International Journal of Climatology, EarlyView.
Regional heavy rainfall events (RHREs) in Guangdong, South China, during 1961–2025 are reassessed using an improved strength index that integrates rainfall intensity, spatial extent and duration. Results reveal a post‐1991 shift towards more frequent and spatially extensive strong and extreme events, with June showing the most pronounced ...

Spatio‐Temporal Analysis of Human Thermal Comfort and Relationships With Large‐Scale Climate Indices Along Ghana's Coastal‐Urban Corridor From 1980 to 2020

International Journal of Climatology, EarlyView.
Four decades of UTCI data show increasing thermal stress along Ghana's coastal‐urban corridor, with very strong heat‐stress days rising by about 1.4 days/year. Random Forest–SHAP analysis with temporal validation identified AOD as the strongest model‐based predictor of monthly UTCI variability, followed by TSA, WHWP, and AMO.

Compound Meteorological and Hydrological Hot‐Dry and Hot‐Wet Extremes Over Global Land Areas: Spatiotemporal Changes, Attribution, and Drivers

International Journal of Climatology, EarlyView.
The changes in joint return period of compound meteorological hot‐dry (CMHHE) and hot‐wet (CMHWE) and compound hydrological hot‐dry (CHHDE) and hot‐wet (CHHWE) extremes were attributed to changes in associated univariate extremes and their dependence.

Climate Trends in Bom Jesus, soybean production region in Piauí

Revista Geama, 2017
Climate is still the main responsible for soybean yield variations, exerting a limiting action on these agricultural systems. In the cerrado “savannah” of Bom Jesus, this crop has shown a growth in cultivated areas over the years, however, productivity ...
