Minimal dynamical systems model of the Northern Hemisphere jet stream via embedding of climate data
Posted on
by
Jet streams are narrow, fast-flowing westerly air currents located near the tropopause, the tropospheric boundary with the higher stratosphere. These jets play a major role in driving the large-scale atmospheric circulation and modulate the frequency, severity and persistence of weather events at […]

Spectral theory for the stability of dynamical systems on large oriented locally tree-like graphs
Posted on
by
The linear stability of large complex systems around their stationary points can be studied with random matrix theory. In one common model, the i.i.d. random matrix model, one assumes a simple statistical form for the interactions between distinct elements of a network.
