Sulfate Aerosol Forcing and Climate Change Seasonality
Explore the impact of sulfate aerosols on seasonal climate change over mid-latitude oceans, uncovering strong seasonality in North Atlantic SST and the role of air-sea feedbacks. Discover the reasons behind sulfate aerosol seasonality, its radiative forcing effects, and contributions to sea surface temperature variabilit
