This La Niña-like warming trend in observations is in disagreement with the El Niño-like warming trend projected by the Coupled Model Intercomparison Project (CMIP) models for both the 20th and...

The Atlantic Meridional Overturning Circulation (AMOC) transports warm and salty upper ocean water to the subpolar North Atlantic where the upper ocean releases some heat to the atmosphere. Due to the surface cooling and the high salinity (i.e., salty), the upper ocean water becomes heavier and thus sinks down to the deep ocean and then... Continue Reading →

I am also currently in a task force team to advance subseasonal (2~4 weeks) forecasts of severe weather activity in the U.S. I have learned so much from weather scientists about how longer-term climate processes...
