Some notable observations... Brings up the topic of the ITCZ, or, Intertropical Convergence Zone, some more. While the air tends to be flowing in one direction on its northern side in this hemisphere, "Monsoon Depressions" frequently form within the ITCZ - but with most never, ever becoming Tropical Depressions, and most never even earning as much as an Invest tag. Besides, 96L is simply not your average ITCZ depression, however. It's been more like a full-on wave that has transcended the ITCZ, all along. What is more, the ITCZ, by very definition, is a vorticity-rich environment. It is one very long trof of low pressure. An elongated nebula of cyclogenesis. I do believe we are indeed viewing incipient banding features, which have been forming overnight. The internal structure of this Low is really not half-bad. Now if it can actually survive all the dry, stable air it has to contend with... I suspect that it is not so much the wind that has "blown" the convection to the south, as much as it has been the effect of all that dry air to the humble cyclone's north that has squashed any real attempt to wrap deep convection all the way around. You can see this quite clearly in this morning's QuikSCAT pass, from 827Z, here and this is still quite evident in the 1037Z TRMM pass |
