Moisture Aggregation and the Cloud Transition Zone Shape Mesoscale Aerosol Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract Mesoscale moisture aggregation and cloud organization in shallow convection have gained much attention regarding their role in Earth's energy budget and cloud feedbacks on climate. Because aerosol particles swell in humid air, mesoscale moisture patterns are expected to be accompanied by corresponding variations in aerosol optical depth (AOD).

Leveraging Multi‐Isotope Systems to Investigate Conflict, Food Insecurity, and Elevated Nitrogen Isotope Values in the Nazca Highlands of Peru During the Late Intermediate Period (1000–1450 CE)

American Journal of Biological Anthropology, Volume 191, Issue 3, November 2026.
ABSTRACT Objectives The physical effects of interpersonal violence are well documented in archaeology, but its broader impacts on population health, mobility, and resource access remain less understood. This article assesses how chronic warfare restricted movement and access to critical resources, altering dietary practices and contributing to ...

Dynamics of Groundwater Flow Along A Topographic Sequence in an Amazonian Tropical Forest: The Role of Soil Permeability and System Structure

Hydrological Processes, Volume 40, Issue 11, November 2026.
Soil permeability, groundwater depth, and topographic structure jointly regulate subsurface flow behavior and isotopic response along a tropical Amazonian toposequence. Plateau environments exhibit greater storage, longer flow paths, and stronger isotopic damping, whereas shallow valley systems show rapid hydrological response and high connectivity ...

Quantifying the Unseen Dengue Burden: A Municipality‐Level Ascertainment Surface for Pará State, Brazilian Amazon

Journal of Medical Virology, Volume 98, Issue 11, November 2026.
ABSTRACT Passive dengue surveillance systematically underestimates true disease burden, and this under‐ascertainment is spatially structured rather than random. In the Brazilian Amazon, municipalities with the weakest notification infrastructure tend to coincide with those presenting the most favorable environmental conditions for vector proliferation.
