What is the Walker Circulation? The El Niño Southern Oscillation, or ‘ENSO’, is one of the major causes of year to year variability in Earth’s climate.

Number two in that list is what makes ENS ...[Read More]

This teleconnection between the ocean and the atmosphere has been the focus of great interest, especially in the context of ongoing global warming. For instance, Cresswell-Clay et al. (2022) noted an expansion of the North Atlantic Os ...[Read More]
