is there a correlation between the amplitude of a tropical wave and its tendency to begin spinnig? and where along a wave is spinning most likely to occur? presently there is a low amplitude wave at about 30w that has some spin within the ITCZ.
Generally higher amplitude waves have more turning within the wind field, particularly on the north side of the wave axis. They can also be somewhat broader, though. Low amplitude waves can organize, too, and in a quicker manner if they happen to have a well-defined source of vorticity/spin (or a means of creating it, like convection) just above the surface.
But, in general, higher amplitude waves tend to have a bit more turning.
