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

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
