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

; Kump and Pollard 2008 ; Walsh et al. 2008 ). Apart from the above processes, an additional atmospheric pathway that can produce Arctic amplification has been proposed recently. The tropically excited Arctic warming (TEAM) mechanism hypothesizes that localized tropical convection near the Maritime Continent can amplify planetary-scale wave (PSW) activity, which leads to enhanced poleward sensible and latent heat transports into the Arctic. As a result of these transports, downward infrared

weaker diurnal tide amplitudes in the MLT region. Interactions between the diurnal tide and planetary waves is the second of the two mechanisms proposed to explain the observed semiannual variation of the tide. Studies supporting this mechanism have involved the use of general circulation models. Norton and Thuburn (1999) suggest that interactions with the quasi-2-day wave, which is strongest at solstice, are responsible for the weak tidal amplitudes found at these times. McLandress (1997
