concludes with further discussion in section 5 . 2. Theoretical considerations How can we, then, explain the MJO in terms the dry dynamics? Under the linear limit, the large-scale tropical atmospheric dynamics consists of a set of the equatorial waves ( Matsuno 1966 ; Yano and Bonazzola 2009 ). Thus, if the MJO is to be explained in terms of the linear dynamics, it must be explained in terms of the slowest-propagating equatorial planetary-scale waves: the Kelvin or the Rossby wave. At first sight, the

the observed IAV. This paper will focus on two sources of natural variability: the equatorial quasi-biennial oscillation (QBO) in zonal wind and the variability in the forcing of stratospheric planetary waves at the tropopause. The former has been studied fairly extensively already, using both observations (e.g., Hasebe 1984 ; Bowman 1989 ; Lait et al. 1989 ; Randel and Cobb 1994 ; Tung and Yang 1994a ; Hollandsworth et al. 1995 ; Randel and Wu 1996 ; Sitnov 1996 ) and models (e.g., Gray

and Karoly 1981 ; Webster 1981 ). These studies, and others, showed that planetary-scale Rossby waves tend to propagate approximately along the arcs of great circles. However, linear theory does not give insight into the behavior of finite-amplitude wave trains when they reach a critical line, where the flow speed equals the phase speed of the waves (e.g., Killworth and McIntyre 1985 ). Recently, Waugh et al. (1994, hereafter WPP) and Brunet and Haynes (1996, hereafter BH) , have used a
