When It Isn’t As Humid As It Feels: Surface Dewpoint and Adaptability in a Changing Climate
Introduction I’ve lived in the Deep South for a few years. It can get pretty humid here. But usually, by the time October and November roll around, the air dries out. Winters are usually pleasant for this transplanted northerner, and even if the dewpoint temperature rises during the cool season, it remains tolerable. But in… Continue reading

Stratiform Precipitation in the New Climate Regime: How the Atmosphere Organizes With a Broad Jet Stream
Stratiform precipitation developed over Georgia even as the jet stream lost definition. This case study shows how the atmosphere built a new vertical pathway for ascent, organized around the freezing level, and sustained a coherent rain band through deformation, layered stability, and microphysical constraints.

Do Rapid Changes in Cloud Opacity and Structure Indicate an Emerging Climate Regime Shift?
Introduction Louis Armstrong famously crooned “I see skies of blue, and clouds of white…” But we know that clouds aren’t always white. We use the term “cloud opacity” to refer to the grayness (or brightness) of a cloud. A cloud looks white when light moves through it with little interference, and it looks darker when… Continue reading
