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 ...

Spatiotemporal Changes and Climate Driving Factors of Compound Precipitation‐Temperature Extreme Events Across Global Land Areas

International Journal of Climatology, EarlyView.
During the period 1901–2024, the dominant proportion of compound dry‐warm extremes in annual, June–July–August (JJA), and December–January–February (DJF) occurrences was the highest among the four types of compound precipitation and temperature extremes across global land areas, accounting for 40.1%, 50.3%, and 28.0%, respectively.

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 ...

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Burrow use by Saharan striped polecat (Poecilictis libyca) in an agricultural area of central Tunisia

The Journal of Wildlife Management, EarlyView.
Saharan striped polecats in agricultural landscapes use many burrows (30–35 per season), facilitated by sandy soils. Burrow sharing is rare and mainly occurs between males and females during mating. Habitat use shifts seasonally, reflecting disturbance and soil conditions. Maintaining stable sandy habitats may be critical for persistence.
