Simple Dynamic Frameworks for Tropical Atmosphere and Ocean

Abstract

In this chapter, free waves in a shallow water model system at the equatorial plane are first described, followed by a discussion of vertical mode separation. Then a number of simple or intermediate tropical atmospheric and oceanic models including the Gill model, the Lindzen--Nigam model, and the Cane--Zebiak model are introduced. These dynamic frameworks will be used in the subsequent chapters for theoretical and physical investigations.
