阿根廷中部的风暴以产生大而严重的冰雹而闻名。该地区的环境条件和与地形的强烈相互作用为强风暴的发生和加强提供了独特的条件。RELAMPAGO（带电，闪电和中尺度/微尺度过程的遥感与自适应地面观测）和CACTI（云，气溶胶和复杂地形相互作用）现场活动于2018年10月至2019年4月在阿根廷中西部部署，收集了该地区前所未有的密集观测。在第10次密集观测期间（2018年11月26日），门多萨省的大部分地区报告了直径4厘米的冰雹。这是首次在门多萨通过多平台观测测量到严重冰雹，因为IOP部署包括多个大气探测、恶劣天气研究中心（CSWR）的观测、轮式多普勒雷达（道斯）以及来自GOES-16上的高级基线成像仪（ABI）和地球同步闪电成像仪（GLM）的高时间分辨率卫星数据。高时间频率探测和对流开始前收集的地面观测进行了分析，允许对流前的环境的详细描述。文中还分析了上升气流的建立和边界层过程在强冰雹发展中的作用。此外，几个GOES-16 ABI和GLM派生产品进行了研究，以测试它们的能力，预测对流的启动，并提供冰雹代理在该地区。
Storms in central Argentina are known for producing large and severe hail. Environmental conditions and strong interaction with topography in this region provide unique conditions for the initiation and intensification of severe storms. The RELAMPAGO (Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations) and CACTI (Clouds, Aerosols, and Complex Terrain Interactions) field campaigns deployed between October 2018 and April 2019 over west-central Argentina have collected unprecedented periods of intensive observation in the region. During the Intense Observation Period (IOP) number 10 (November 26, 2018), 4 cm diameter hail was reported over wide areas of the province of Mendoza. This was the first time a severe hailstorm was measured with multi-platform observations in Mendoza as the IOP deployment included multiple atmospheric soundings, observations from the Center for Severe Weather Research (CSWR) Doppler on Wheel radars (DOWs) and high temporal resolution satellite data from the Advanced Baseline Imager (ABI) and the Geostationary Lightning Mapper (GLM) onboard GOES-16. High-temporal frequency soundings and surface observations collected prior to the convection initiation are analyzed, allowing a detailed description of the pre-convective environment. The establishment of the upslope flow and the role of boundary layer processes that resulted in the development of the severe hailstorm are also analyzed. In addition, several GOES-16 ABI and GLM derived products are investigated, in order to test their ability to forecast convective initiation and provide hail proxies in the region.
