Abstract: otivated by Dunkerton et al., a climatological study of 54 developing easterly waves in 1998?2001 was performed. Time-lagged composites in a translating reference frame following the disturbances indicate a weak meridional ...

Abstract: ecently Asaadi et al. found that an easterly wave (EW) train over the Atlantic and eastern Pacific is oriented in a southeast?northwest direction because of the observed tilt in the easterly jet. This tilt results in only ...

Abstract: shallow-water model is used to study the role of critical layers in tropical cyclogenesis. Forced and unforced problems of disturbances on a parabolic jet associated with weak basic-state meridional potential vorticity ...
