Characterising Vento Norte Downslope Windstorms and Their Thermal Impacts in Southern Brazil
International Journal of Climatology, EarlyView.Using 20 years of hourly INMET observations in Santa Maria (southern Brazil), we identify 189 Vento Norte (VNOR) downslope windstorms, ~72% in winter, marked by abrupt warming, drying and strong northerly gusts. Across five biometeorological indices (TEFW, TDI, THI, HDI, Humidex), VNOR hours consistently show significantly higher thermal discomfort ...

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.

Structure and Propagation of Mesoscale Cyclonic Eddies in the Brazil–Malvinas Confluence
International Journal of Climatology, EarlyView.Between 1993 and 2022, 1386 cyclonic eddies were identified in the Brazil–Malvinas Confluence, one of the most energetic regions of the South Atlantic. While most eddies dissipated locally, a smaller number of individuals, more energetic, and longer lived propagated predominantly south‐westward and north‐eastward, driven by topographic constraints and ...

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.
