Impact of Sudden Stratospheric Warmings on the Stratosphere‐To‐Troposphere Transport of Ozone
GEOPHYSICAL RESEARCH LETTERS
14 january 2025
Jae Won Lee, Amy H. Butler, John Albers, Yutian Wu...
Sudden stratospheric warmings (SSWs) can significantly impact tropospheric weather systems. Previous studies suggest that SSWs may also influence s...
