Pinpointing Effects of Hadley Cell Expansion
As a major atmospheric circulation system spreads farther poleward, some regions are drying out. But as time passes, will this drying be symmetrical across the globe?

Two Paired Eddies Travel Faster and Further Than One
The first observational evidence of dipole eddy pairs (modons) in the southern midlatitude ocean reveals that they move faster, live longer, and travel greater distances compared to single eddies.
