Tropical waves are more prononced in the upper levels,around 700mb.What is the link to track these values?
Also,what is the difference between a TWave,and an Easterly wave?Just a semantic appelation,or really a difference in nature?
Here in Guadeloupe,we got a strong squall this morning,and recently a thunderstorm,due to the curent wave,which seems consequently disrupted since yersterday!!!.
So long to the upcoming waves,and other disturbances,which undoubtly,had to arrived as the season advenced........

Easterly/Tropical Waves
Hi HUC,
A tropical wave and easterly wave behave the same way in that they lead moisture into a particular area. They are pretty much the same thing in the tropics, but easterly waves can be found elsewhere. I have tracked easterly waves across the southeast US around the southern periphery of high pressure, at different times of the year, even in the winter. The upper level trough (500mb) associated with a tropical/easterly wave will pass by first, followed by the mid level trough (700mb), then lower level trough (850mb). There is a usually more pronounced wind shift from NE-SE in the upper and mid levels as opposed the lower levels if the wave is weak. If the wave is well organized down the surface, there will usually be a surface wind shift from the ENE to the ESE or even NE to SE (a strong wave). The drier flow ahead of the wave will get replaced by a juicier flow behind the wave and during the wave passage there can be gusty showers and thunderstorms followed by an increase in humidity. Hope this helps.
