Cazenave‐Dickstein‐Weissler‐Type Extension of Fujita'S Problem on Heisenberg Groups

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 2, Page 499-511, 30 January 2026.
ABSTRACT This paper investigates the Fujita critical exponent for a heat equation with nonlinear memory posed on the Heisenberg groups. A sharp threshold is identified such that, for exponent values less than or equal to this critical value, no global solution exists, regardless of the choice of nonnegative initial data. Conversely, for exponent values

Strong Wind‐Driven Oceanic Forcing on Decadal SST Variability Over the Global Ocean

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Gu et al. (2024, https://doi.org/10.1029/2023GL107401) recently provided the first quantitative assessment of oceanic and atmospheric forcing on decadal sea surface temperature (SST) variability globally in observations. However, the validity of their simplified statistical method in the complex climate system remains uncertain.

Atmospheric Specifications for Infrasound Studies: 2. The Added Value of a High‐Top Model, UA‐ICON

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.
Abstract Infrasound monitoring activities that deal with long‐range acoustic propagation, as within the Comprehensive Nuclear‐Test‐Ban Treaty's (CTBT), need accurate and operational modeling of the atmosphere up to the lower thermosphere. Yet, operational meteorological products issued by weather services are topped at around 80 km altitude with a ...
