Interannual Influence of Antarctic Sea Ice on Southern Hemisphere Stratosphere‐Troposphere Coupling
GEOPHYSICAL RESEARCH LETTERS
01 august 2024
Divya Rea, Dillon Elsbury, Amy H. Butler, Lantao S...
While weakening of the boreal polar vortex may be caused by autumnal Arctic sea ice loss, less is known about the interannual influence of Antarcti...
Northern Hemisphere Stratosphere‐Troposphere Circulation Change in CMIP6 Models: 2. Mechanisms and Sources of the Spread
JOURNAL OF GEOPHYSICAL RESEARCH: ATMOSPHERES
