                         incursions in South America, but some fundamental differences can 
                         be pointed out: (1) further northward Rossby wave amplification; 
                         (2) strong upward vertical motion within a deep nearly saturated 
                         layer and (3) a conditional symmetric instability layer, in 
                         response to strong vertical shear, beneath a layer of weak 
                         conditional instability, and above a significant near-surface 
                         vertical depth where temperatures hover around 0C.",
