This chapter is dedicated to a fundamental understanding of the physical mechanisms for connections between climates in remote locations or large-scale teleconnection patterns. It starts with a review of equatorial waves. This is followed by an introduction to conceptual models of the atmospheric response to tropical heating. Large-scale overturning circulations and their variability are described. The chapter ends with a discussion on how perturbations in the tropics propagate their effect on high latitudes in both hemispheres.
