RELAMPAGO (Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations) will observe convective storms in the lee of the Andes Mountains in central Argentina. Storms in this region are poorly represented by weather and climate models and produce high impact weather in the lee of the Andes mountains in Argentina near the major cities of Cordoba and Mendoza. RELAMPAGO will be a 45-day project from 1 November - 15 December 2018. RELAMPAGO examines what are perhaps the "world's most intense thunderstorms" per satellite observations, studying the processes that generate intense convection and severe weather that accompanies them, including heavy precipitation, severe hail and winds, and tornadoes. By observing storms with new tools and techniques in detail in a region that has some similarities and key differences with the US Great Plains, RELAMPAGO is designed to make contributions to improve prediction of severe convective storms globally, including in the US. In addition, RELAMPAGO's international coordination is integrated to directly improve high impact weather prediction in Latin America. This project involves a collaboration between researchers at the University of Illinois and Colorado State University to study the processes that generate intense convection and precipitation in this region. The project includes a network of research-quality fixed and mobile radars, atmospheric soundings, and storm process measurements in concert with other RELAMPAGO measurements (including from the DOE ARM Mobile Facility-1) to characterize the environment and internal structure of heavy-rain-producing storms. These measurements, value-added products, analyses, and modeling activities are focused on understanding the precursors and processes within and external to the storms to address hypotheses on relevant to heavy rainfall production in Argentinean convective storms in this poorly observed, yet vulnerable region. Research activities also include developing forecast models that are crucial for developing the field campaign operations and forecast planning. Contributions include RELAMPAGO education and outreach activities.The region of the lee of the Andes mountains in west-central Argentina generates some of the most intense and organized convective systems on earth. These storms, initiated commonly near, and interacting with the complex terrain of the Andes and Sierras de Córdoba, produce frequent heavy rainfall that is known to lead to damaging flash floods. The RELAMPAGO (Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations) field campaign, from 1 November to 15 December 2018, is designed to provide a comprehensive array of profiling, surface, and remote sensing datasets with fixed and mobile platforms capable of characterizing the evolution of thermodynamic, kinematic, and microphysical measurements in and near convective storms on fine time and space scales. In this project, the NCAR S-PolKa dual-frequency dual-polarization, dual-wavelength S- and Ka-band radar, a network of Doppler on Wheels X-Band radars, frequent soundings, surface thermodynamic, kinematic, and microphysical measurements, and continuous water vapor profiling from the NCAR Water Vapor DIfferential Absorption Lidar (WVDIAL) platform, in concert with other RELAMPAGO measurements are used to characterize the environment and internal structure of heavy-rain-producing storms. These measurements, value-added products, analyses, and modeling activities focus on understanding the precursors and processes within and external to the convective storms to address hypotheses on relevant to heavy rainfall production in Argentinean convective storms in this poorly observed, yet vulnerable region. Leadership in research activities and configure forecast models that are crucial for developing the field campaign operations and forecast planning, as well as contributions to the RELAMPAGO education and outreach activities during the campaign are undertaken.

Relampago（具有自适应地面观测的电气化，闪电和中尺度/微观过程的遥远灵敏度）将观察到阿根廷中部安第斯山脉山脉的对流风暴。该地区的暴风雨在天气和气候模型中的代表性很差，并在科尔多瓦和门多萨主要城市附近的阿根廷安第斯山脉的李的Lee产生了高影响的天气。 Relampago将从2018年11月1日至12月15日开始为期45天的项目。Relampago考试每个卫星观察的“世界上最激烈的雷暴”可能是什么，研究了产生强烈的联系和恶劣天气的过程，包括沉淀，严重的降雨，严重的Hail和Winds和Tornadoes。通过在与美国大平原有一些相似之处和关键差异的地区详细观察风暴，旨在提高全球严重对流风暴的预测，包括在美国，包括在美国。此外，Relampago的国际协调旨在直接改善拉丁美洲的高影响力预测。该项目涉及伊利诺伊大学和科罗拉多州立大学研究人员之间的合作，以研究在该地区产生激烈的会议和精确度的过程。该项目包括一个研究质量固定和移动雷达的网络，大气响料以及与其他Relampago测量结果（包括从DOE ARM移动设施1）共同进行的风暴过程测量网络，以表征产生大量暴风雨的环境和内部结构。这些测量值，增值产品，分析和建模活动的重点是理解风暴内部和外部的前体和过程，以解决这个在这个较脆弱但脆弱地区的阿根廷对流风暴中与大降雨产生有关的假设。研究活动还包括开发预测模型，这些模型对于制定现场活动运营和预测计划至关重要。贡献包括Relampago教育和外展活动。阿根廷中西部安第斯山脉的李的李的区域产生了地球上最激烈，最有组织的对流系统。这些暴风雨通常在附近引发，并与安第斯山脉和塞拉斯·德·科尔多巴的复杂地形相互作用，经常会产生大雨，这会导致破坏山洪洪水。从2018年11月1日至2018年12月15日，Relampago（电气化，闪电和中尺度上的远程敏感性，具有自适应地面观察的远程敏感性）旨在提供一系列具有固定和移动平台的固定和移动平台，并构成热力学，动力学，动力学，动力学，动力学，动力学，动力学，动力学，动力学，动力学，动力学，动力学和移动的平台的全面范围，并提供全面秤。 In this project, the NCAR S-PolKa dual-frequency dual-polarisation, dual-wavelength S- and Ka-band radar, a network of Doppler on Wheels X-Band radars, frequently soundings, surface thermodynamic, kinematic, and Microphysical measurements, and continuous water vapor profiling from the NCAR Water Vapor DIfferential Absorption Lidar (WVDIAL) platform, in concert使用其他Relampago测量值来表征产生重度风暴的环境和内部结构。这些测量值，增值产品，分析和建模活动着重于理解对流风暴内部和外部的前体和过程，以解决这个在这个较脆弱但脆弱的地区的阿根廷对流风暴中与大降雨产生有关的假设。研究活动和配置预测模型的领导能力对于制定现场活动运营和预测计划至关重要，以及在竞选期间对Relampago教育和外展活动的贡献。
