An internally generated 150-day periodicity is newly identified in the Southern Hemisphere extratropical large-scale atmospheric circulation, which arises from the annular mode’s propagating regime.
Scientists provide a process-level understanding of how mesoscale convective systems modify the evolution of the large-scale Rossby wave packet downstream and the jet stream.
A significant increasing trend of turbulence in upper atmosphere over northern Eurasia is attributed to intense anthropogenic activities.
New research suggests an atmospheric connection between Arctic sea ice melt and anthropogenic aerosol pollution over the Tibetan Plateau.
Scientists find that reduced aerosol emissions correspond to fewer extremely cold days.
Simulations that test different approaches to modeling radiation suggest a commonly used scheme fails to fully capture changes in midlatitude circulation associated with climate change.
A simplified view of ozone chemistry can cause climate models to overestimate the response of jet streams to increasing greenhouse gases.
An idealized climate model suggests polar warming stabilizes the jet stream and reduces atmospheric blocking at midlatitudes.
