A 20-Year Record of the Subpolar AMOC: Key Findings from the SCOTIA Program

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “The Scotland-Canada overturning array (SCOTIA): twenty years of meridional overturning in the subpolar North Atlantic” by Fox et al. (2026). The SCOTIA observing array provides a new 20-year record of the Atlantic meridional overturning circulation (AMOC) at subpolar latitudes from 2004 to 2024. By integrating mooring data, Argo... Continue Reading →

Oceanic Slow-Lane: Why the Subtropical Gyre Holds the Key to How the ITCZ Responds to AMOC Slowdown

This blog post, created by NotebookLM, is based on “On the Atlantic extratropical-tropical teleconnection in response to external freshwater forcing” by Joshi an Zhang (2026). This research study utilizes a coupled climate model to investigate how a massive influx of freshwater in the North Atlantic triggers a chain reaction that shifts the Intertropical Convergence Zone (ITCZ) southward. The authors demonstrate that... Continue Reading →
