Topological modes of variability of the wind-driven ocean circulation
Gisela D. Charó, Denisse Sciamarella, Juan Ruiz +2
Templexes are topological objects that encode the branching organization of a flow in phase space. We build on these objects to introduce the concept of topological modes of variab…

Forecast error growth: A dynamic-stochastic model
Eviatar Bach, Dan Crisan, Michael Ghil
There is a history of simple forecast error growth models designed to capture the key properties of error growth in operational numerical weather prediction (NWP) models. We propos…

Intraseasonal atmospheric variability under climate trends
Bernardo Maraldi, Henk Dijkstra, Michael Ghil
Low-order climate models can play an important role in understanding low-frequency variability in the atmospheric circulation and how forcing consistent with anthropogenic climate…
