Airborne Measurements of the Nocturnal Low-level Jet and Wave Disturbances in the Stable Boundary Layer in PECAN (Plains Elevated Convection At Night)

该奖项是为参与平原高架对流在夜间（PECAN）现场活动。 PECAN将于2015年夏天在美国中部举行。 该项目的重点是大平原地区经常发生的夜间雷暴复合体。 将为实地实验部署各种观测系统，包括多架飞机、移动的雷达和地面系统，这些系统可以对低层大气中的风和粒子进行剖面分析。 这个个人奖项为研究人员提供资金，让他们参与这项活动，并利用怀俄明州国王航空大学（UWKA）研究飞机的数据。 UWKA将对雷暴复合体和预期雷暴发展区域附近的近地表环境进行采样，以便更好地了解有助于这些复合体生存的触发因素和强迫机制。 该项目将有助于增加对这些对流系统的了解，以便更好地预测和警告公众危险天气。 PECAN活动的指导委员会已经确定了四个主要研究课题：1）夜间对流的产生和中尺度对流团的早期演变; 2）钻孔和其他波状扰动; 3）夜间中尺度对流系统的动力学和微物理学; 4）夜间中尺度对流系统的动力学和微物理学; 5）夜间中尺度对流系统的动力学和微物理学。4）夜间对流发生和演变的预报。 该奖项下的这项研究将有助于解决这些主题。 该项目将以前所未有的详细程度记录孔和孤子的结构、性质和演变，在观察到的环境稳定性和剪切剖面的背景下深入了解孔/孤子的行为，并研究它们在对流启动中的作用。 一个相关的项目目标是研究大平原上空夜间低空急流的中尺度运动学和动力学。

This award is for participation in the Plains Elevated Convection at Night (PECAN) field campaign. PECAN will take place in the central United States in the summer of 2015. The focus of the project is on overnight thunderstorm complexes that regularly occur in the Great Plains area. A variety of observational systems will be put in place for the field experiment including multiple aircraft, mobile radars, and ground-based systems that can profile the wind and particles in the lower atmosphere. This individual award provides funding for researchers to take part in the campaign and make use of data from the University of Wyoming King Air (UWKA) research aircraft. The UWKA will sample the near-surface environment near thunderstorm complexes and areas of anticipated thunderstorm development in order to better understand the triggers and forcing mechanisms that help these complexes survive. This project will help to increase understanding of these convective systems in order to better predict and warn the public of hazardous weather. The project will also help to train the future generation of scientists by involving multiple graduate students in the research.The steering committee for the PECAN campaign has identified four main research topics to be addressed: 1) Nocturnal convection initiation and early evolution of mesoscale convective clusters; 2) Bore and other wave-like disturbances; 3) Dynamics and microphysics of nocturnal mesoscale convective systems; 4) Prediction of nocturnal convection initiation and evolution. This research under this award will help to address each of these topics. The project will document the structure, properties and evolution of bores and solitons in unprecedented detail, gain insight in the behavior of bores/solitons in the context of the observed ambient stability and shear profiles, and to examine their role in convective initiation. An associated project goal is to study the mesoscale kinematics and dynamics of the nocturnal low level jet over the Great Plains.
