Correlated Random Processes in Physical and Radar Meteorology

该奖项允许研究与雷达气象学，云物理学和辐射通过大气层的传输有关的几个相互交织的问题。 提案中的具体研究任务将回答有关为什么有些雨滴不会以其终端速度下落，辐射如何穿过分层尘埃以及过冷水如何冻结的问题。 这些主题具有广泛的应用范围，从改进雷达对降雨的估计到影响材料科学。 该研究将包括国际合作者，并为学生提供教育和培训机会。 研究人员将研究云和降水物理学、雷达气象学和辐射传输中相关波动的存在和影响。 理论研究，计算机模拟，现场和实验室数据分析将进行回答有关五个主要研究课题的问题：下落雨滴与其预期终端速度的偏差，通过垂直分层介质的辐射传输，使用高分辨率和短脉冲数据的雷达后向散射的相干性，降水的时空相关性及其对尺度的依赖性，以及压力波动对过冷水滴成核和冻结的影响。

This award allows for research on several intertwined issues related to radar meteorology, cloud physics, and the transfer of radiation through the atmosphere. The specific research tasks within the proposal will answer questions regarding why some raindrops do not fall at their terminal velocities, how radiation travels through layered dust, and how supercooled water freezes. These topics have a wide range of application, from improving radar estimates of rainfall to impacting materials sciences. The research will include international collaborators and provide educational and training opportunities for students. The researcher will be studying the presence and impact of correlated fluctuations in cloud and precipitation physics, radar meteorology, and radiative transfer. Theoretical studies, computer simulations, and field and laboratory data analysis will be conducted to answer questions related to five main research topics: deviations of falling raindrops from their expected terminal speed, radiative transfer through a vertically stratified medium, coherence in radar backscatter using high resolution and short pulse data, temporal and spatial correlations of precipitation and their dependence on scale, and the effects of pressure fluctuations on the nucleation and freezing of supercooled water droplets.
