Convective storm life cycle and environments near the Sierras de Córdoba, Argentina

Satellite observations have revealed that some of the world's most intense deep convective storms occur near the Sierras de Córdoba, Argentina, South America. A C-band, dual-polarization Doppler weather radar recently installed in the city of Córdoba in 2015 is now providing a high-resolution r...
