Argentina. With time, this will be a promising avenue to explore hail within this region, but currently the data record is not extensive enough for a thorough analysis. Fig . 1. Southern South America with topography shaded and the study area outlined. As a result, the most comprehensive way to examine the climatology of hail in subtropical South America and compare these results to other parts of the world is to use passive microwave satellite observations of ice hydrometeors. These measurements have

Period (15 October 2018–30 April 2019), and a 1.5-month intensive observation period (IOP; 1 November–15 December 2018) that included Gulfstream-1 (G-1) aircraft flights. The campaign overlapped with the collaborating multi-agency, National Science Foundation (NSF)-led Remote Sensing of Electrification, Lightning, and Mesoscale/Microscale Processes with Adaptive Ground Observations (RELAMPAGO) field campaign [see companion article by Nesbitt et al. (2021) ]. The processes targeted by CACTI

, mesoscale convective systems, multicell storms), and conceptual models of storm life cycle and life cycle transitions and their associated hazard probabilities, generated from U.S. storms consistent across global regions? How do proxies for severe storm frequency from satellites and large-scale models compare with detailed observations in severe storms, particularly in regions where the physical processes producing severe weather may differ? The answers to these questions ultimately impact our ability

1. Introduction Satellite observations have revealed that some of the world’s most intense thunderstorms occur across subtropical South America and, more specifically, in northern and central Argentina (e.g., Zipser et al. 2006 ; Romatschke and Houze 2010 ; Cecil and Blankenship 2012 ; Houze et al. 2015 ). These thunderstorms typically develop near a secondary mountain range to the east of the Andes called the Sierras de Córdoba (SDC), and they have been associated with severe weather
