reasons for the banded structure not well understood
organized convection theory
- latent heat is confined to a limited area
- instability aloft (cold pool) to counteract the trade wind inversion (stability)
- thunderstorms develop quickly
- no 300 mb jet stream to vent the rising parcels of air, so sinking parcel organize to form clear bands
- latent heat release and heat by compression cause a high pressure center aloft, from which parcels diverge (similar to MCC behavior)
near-surface eye and eye wall - imbalance of the pressure gradient, friction, and coriolis forces
$-\frac{1}{\rho}\frac{\Delta p}{\Delta x} - C_0 V + 2\Omega V \sin \phi = -\frac{V^2}{r}$
