Thicker clouds and accelerated Arctic sea ice decline: The atmosphere‐sea ice interactions in spring
Observations show that increased Arctic cloud cover in the spring is linked with sea ice decline. As the atmosphere and sea ice can influence each other, which one plays the leading role in spring remains unclear. Here we demonstrate, through observational data diagnosis and numerical modeling, that...
