Abstract This study investigates the impact of the lower‐thermospheric winter‐to‐summer circulation on the thermosphere's thermal structure and meridional circulation. Using NCAR TIE‐GCM, we compare simulations w...

Abstract We investigate the skill of the fully initialized decadal forecasting system EC‐Earth3 in re‐forecasting the semiannual occurrence frequencies of synoptic‐scale atmospheric circulation types in the extratr...

Abstract Using an idealized model of the Atlantic meridional overturning circulation (AMOC), we test whether changes in the statistical properties of an AMOC time series can reveal Critical Slowing Down (CSD) and serve a...

The Atlantic meridional overturning circulation (AMOC) plays a crucial role in regulating global and regional climate by distributing heat meridionally across the planet. Future projections indicate a weakening of the AM...

Abstract The storm‐time temperature difference with respect to its quiet‐time expectation (ΔT) in the mesosphere and lower thermosphere were studied during the extreme storms on 2024 Mother's Day and 2003 Halloween ...

Abstract The Quasi‐Biennial Oscillation (QBO) of descending zonal winds is the leading mode of tropical stratospheric variability. Numerous studies have explored its connection with the troposphere, including its sensi...

Abstract The present article sets out to analyze instances of racial discourse circulating in both the Brazilian and international media during a particular time of crisis - the Covid 19 pandemic - and follows this analy...

The climatic variations observed in recent decades in Patagonia have affected the dynamics of the Andean forests. In this study, new and existing Austrocedrus chilensis chronologies were subjected to analysis in 28 sites...
