This is lecture 15 in the series "Introduction to the Mathematics of Climate" offered at the University of Minnesota in 2014 with the support of MCRN and The Institute for Mathematics and its Applications.

It introduces the equilibrium types of nodes, saddles, and spirals and presents the classification of two-dimensional linear systems in the trace-determinant plane. It concludes with initial comments on the topological classification of equilibria.
