Abstract

How can the Madden–Julian oscillation (MJO) be identified in observational data? Some methods identify the MJO using wind data only, other methods use cloudiness or precipitation data only, and others use a combination of winds and cloudiness. In a sense, each MJO index offers a different definition of what the MJO is. While MJO indices have traditionally been empirical, the MJO skeleton model offers the possibility of a theoretical definition of the MJO.
