In the beginning of September, our article on how the type of El Niño, i.e. whether it is centered in the Central Pacific or the Eastern Pacific, influences its global correlation patterns got published in Geophysical Research Letters.
We use the concept of curvature for complex networks to differentiate short-range and long-range links in climate networks constructed from surface air temperature data from the last 70 years. We find that Central Pacfic El Niños have drastically different correlation patterns than Eastern Pacific ones, and that the Central Pacific region itself is rather uncorrelated during both Central Pacific and Eastern Pacific warming events.
