abstract = "On 23 July 2013, a snowstorm hit southern Brazil causing material
damage and two deaths. Radar reflectivity and lightning data
revealed a rare thundersnow occurrence. This study revealed that a
Rossby wave propagation followed a typical pattern of cold
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 0°C.",
