Elementos para discutir Significativa densidad de rayos en sector post-frontal, sobre Patagonia chilena. Claro indicio de inestabilidad post-frontal: nubes Cu de gran desarrollo vertical.Análisis meteorológico (GFS) confirma inestabilidad postfrontal (CAPE>0) debido a enfriamiento en altura. Precipitaciones significativas en esta zona. Rayos en sector postfrontal en 3 clusters sobre la costa/Andes. Control topográfico o artefacto de las observaciones? Otras fuentes de datos Ausencia de rayos a lo largo del frente frío. Actividad eléctrica a lo largo del frente cálido.
