Airplane Emergency Landing Due to Quick Development of Mesoscale Convective Complexes

Some meteorological phenomena in South America develop quickly and take on large dimensions. These cause disasters for aviation, such as incidents accidents. Mesoscale convective complexes (MCCs) forced a commercial airplane into an emergency landing at Ezeiza International Airport Buenos Aires (Argentina) October 2018. The took off from São Paulo (Brazil) to Santiago (Chile) had alternate after encountering unanticipated agglomerations of MCCs along the flight route; its structure was seriously damaged, which affected safety flight. A synoptic thermodynamic analysis atmosphere, prior event, made based GOES16 infrared satellite data, radiosonde maps several variables stream lines, temperature advection, surface layer thickness CPTEC/INPE NCEP reanalysis data. main observed processes that influenced formation development conglomerates were following: (1) cyclogenesis baroclinic cyclone cold front; (2) coupling subtropical polar jet streams; (3) advection warm humid air low-level stream.
