项目摘要

Thunderstorms that produce deep hail accumulations pose a substantial risk to life and property resulting in motor vehicle accidents, road closures, airport delays, urban and river flooding, and water rescues. Data inhomogeneities and inadequacies in monitoring hail characteristics in thunderstorms leads to low confident in projecting future hail occurrence and evaluation of future climate predictions. The overarching goal of the research is to analyze the microphysical and dynamical conditions necessary for large amounts of in-cloud hail production that lead to deep surface hail accumulations by developing and validating a robust set of characteristic storm properties unique to significant hail accumulation; determining the role of mechanisms enhancing hail production; and determining temporal and spatial variation of hail accumulations in observations and simulations. Intellectual Merit:The intellectual merit lies in its contribution to a comprehensive understanding of the dual-polarization and lighting characteristics in severe thunderstorms with significant hail accumulations; how and why they are linked to environmental conditions, storm morphology, terrain, and outflow boundaries; and if state-of-the-art regional climate and weather forecasting models are capable of reproducing hail accumulation characteristics derived from observations. The research will advance our understanding of processes contributing to large hail/graupel production in thunderstorms, improve the forecasting of extreme events that cause natural disasters, and extend current capabilities to directly benefit society. Broader Impacts:The broader impacts are that the studies will aid in better forecasting and nowcasting events with significant hail accumulation and provide basis for evaluating forecasting and regional climate simulations. Hailstorms have had large economical impacts through damage to property and agriculture with livestock fatalities and human injuries. This study will provide better insight if hail accumulation also provides useful information to issue reliable warnings to the public and assistance in severe weather management. Undergraduates and graduate students will participate in the scientific research through independent studies, internships, and a Ph.D. thesis. The project will promote the collaborations between the University Corporation for Atmospheric Research's Significant Opportunities in Atmospheric Research and Science program and the University of Colorado's Summer Multicultural Access to Research Training program, which are intended for underrepresented undergraduate students in science, math, and engineering.
雷暴产生的深冰雹积累对生命和财产造成重大风险,导致机动车事故,道路封闭,机场延误,城市和河流洪水以及水上救援。数据不均匀和雷暴冰雹特征监测的不足导致预测未来冰雹发生和评估未来气候预测的信心不足。该研究的总体目标是分析大量云中冰雹产生所需的微物理和动力条件,这些条件导致深地表冰雹积聚,方法是开发和验证一套强有力的显著冰雹积聚所特有的风暴特性;确定增强冰雹产生的机制的作用;并确定观测和模拟中冰雹积聚的时空变化。智力价值:智力价值在于它有助于全面了解具有显著冰雹积累的严重雷暴的双偏振和照明特性;它们如何以及为什么与环境条件,风暴形态,地形和外流边界相关联;以及最先进的区域气候和天气预报模型是否能够再现从观测中得出的冰雹积累特性。这项研究将促进我们对雷暴中产生大冰雹/霰的过程的理解,改善对导致自然灾害的极端事件的预测,并扩大目前的能力,直接造福社会。更广泛的影响:更广泛的影响是,这些研究将有助于更好地预报和临近预报具有显著冰雹积累的事件,并为评估预报和区域气候模拟提供基础。雹暴对财产和农业造成破坏,造成牲畜死亡和人员受伤,从而产生巨大的经济影响。这项研究将提供更好的洞察力,如果冰雹积累也提供了有用的信息,向公众发出可靠的警报,并在恶劣天气管理的援助。本科生和研究生将通过自主学习,实习和博士学位参与科学研究。论文该项目将促进大学大气研究公司的大气研究和科学计划的重要机会与科罗拉多大学的夏季多元文化研究培训计划之间的合作,该计划旨在为科学,数学和工程方面代表性不足的本科生提供服务。
