Flood Modelling Evaluation in a Semiarid Catchment: The Role of a Soil Mineralogical Index From Satellite Imagery

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
ABSTRACT The Mediterranean region is characterized by the occasional occurrence of intense rainfall events. Along with lithological, geomorphological, and land use factors, these events influence the hydrosedimentary dynamics of drainage basins, potentially causing torrential floods.

INVESTIGAÇÃO SOBRE MÉTODOS PARA REDUÇÃO DA DIMENSIONALIDADE DOS DADOS EM IMAGENS HIPERESPECTRAIS

Revista Brasileira de Cartografia, 2009
Neste estudo é proposta uma nova metodologia para fins de redução da dimensionalidade dos dados em imagens hiperespectrais. Nesta abordagem, parte-se da suposição de que a curva de resposta espectral em cada pixel, pode ser adequadamente descrita por um ...

Nocturnal boundary layer turbulence regimes analysis during the BLLAST campaign [PDF]

Atmospheric Chemistry and Physics, 2019
A night-time turbulence regime classification, the so-called “HOckey-Stick Transition ” (HOST) theory, proposed by Sun et al. (2012) from the Cooperative Atmosphere–Surface Exchange Study-1999 (CASES-99) is explored using data from the Boundary-Layer ...

Social roles and resource competition mediate intraspecific interactions of Chilean Flamingo (Phoenicopterus chilensis) in southern Brazil

Journal of Zoology, Volume 329, Issue 3, Page 257-270, July 2026.
In social birds such as flamingos, intraspecific interactions are frequent and play a key role in flock cohesion, communication, and the establishment of social networks. Understanding the patterns and drivers of these interactions can provide valuable ecological insights and inform management, husbandry, and conservation practices.

Enhanced Moisture Uptake Fuels North Atlantic Tropical Easterly Waves Precipitation in a Downscaled CMIP6 Projection

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Tropical easterly waves (TEWs) are critical drivers of the tropical North Atlantic hydroclimate, yet their future behavior remains uncertain. Using a high‐resolution, dynamically downscaled, bias‐corrected CMIP6 data set and a Lagrangian moisture tracking approach, we provide the first comprehensive, basin‐wide projections of future changes in

Three‐Year Characterization of Boundary Layer Dynamics From GNSS Zenith Wet Delay Spectral Analysis

Atmospheric Science Letters, Volume 27, Issue 6, June 2026.
Three years of GNSS zenith wet delay observations at Payerne reveal that spectral parameters—cutoff frequency α and variance σ2—capture robust seasonal cycles in boundary layer turbulence (R2 = 0.54 for α). Their inverse coupling tightens to r = −0.82 under summer convection, encoding regime‐dependent physics.

Extreme rainfall in Madeira: the June 2023 weather event

Weather, Volume 81, Issue 6, Page 164-171, June 2026.
This study investigates the meteorological conditions behind the extreme precipitation event on 6 June 2023 over Madeira Island, Portugal. The event set a national daily record of 497.5mm and was unusual for occurring in early summer, as most extremes in the region occur in winter.

Compound dry-hot-fire events connecting Central and Southeastern South America: an unapparent and deadly ripple effect

npj Natural Hazards
South America has experienced severe compound drought-heatwaves (CDHW), exacerbating fires. Recently, the unprecedented Pantanal 2020 fire season (P20F), burning a third of the biome, resulted in well-reported local impacts on the ecosystem, economy, and
