Projections of Meteorological Drought and Potential Evapotranspiration Using the RegCM4 Over Northeastern Iran

open access: yesInternational Journal of Climatology, EarlyView.
We downscale CanESM2 with the Regional Climate Model version 4 (20 km) and evaluate against 15 stations to derive monthly PET (Hargreaves–Samani) and SPEI for northeastern Iran (1990–2009, 2040–2059, 2080–2099). Results show robust PET increases and a shift toward more negative monthly SPEI—especially April–September—indicating earlier onset and longer

Observed Linkages Between Marine Heatwaves and Extreme Weather Over Land: A New Zealand Case Study

open access: yesInternational Journal of Climatology, EarlyView.
Marine heatwaves consistently warm New Zealand's land surface, but rainfall impacts occur only when synoptic systems enable moisture transport. This 38‐year analysis shows MHWs act as thermodynamic background drivers of heat and conditional amplifiers of extreme rainfall events or droughts.

Compound‐Specific Stable Isotope Analysis Improves the Association Between Dairy Fatty Acid Biomarkers and Dairy Intake: A Secondary Analysis

open access: yesLipids, EarlyView.
ABSTRACT Increasing evidence suggests that dairy consumption may decrease the risk of chronic diseases. However, this association remains unclear due to methodological limitations. As a part of a secondary analysis, we used compound‐specific stable isotope analysis to increase the accuracy of the dairy FA biomarkers (15:0, 17:0), considering that each ...
