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.
Global Warming Intensifies Turbulence Over Northern Eurasia
A significant increasing trend of turbulence in upper atmosphere over northern Eurasia is attributed to intense anthropogenic activities.
Pollution over the Tibetan Plateau Linked to Sea Ice Loss in the Arctic
New research suggests an atmospheric connection between Arctic sea ice melt and anthropogenic aerosol pollution over the Tibetan Plateau.
Cleaner Air Takes Some of the Bite out of European Winters
Scientists find that reduced aerosol emissions correspond to fewer extremely cold days.
How Will the Jet Stream Respond to Future Warming?
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.
Including Ozone Complexities in Climate Change Projections
A simplified view of ozone chemistry can cause climate models to overestimate the response of jet streams to increasing greenhouse gases.
Polar Warming Makes the Jet Stream Stable, Not Wavy or Blocked
An idealized climate model suggests polar warming stabilizes the jet stream and reduces atmospheric blocking at midlatitudes.
