Correlated Random Processes in Physical and Radar Meteorology

该奖项允许对几个相互交织的问题进行研究，这些问题与雷达气象学、云物理和大气中的辐射传输有关。该提案中的具体研究任务将回答以下问题：为什么一些雨滴没有以其最终速度下降，辐射如何通过层状尘埃传播，以及过冷水如何冻结。这些主题有着广泛的应用，从改进雷达对降雨量的估计到影响材料科学。这项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、雷达气象学和辐射传输中相关波动的存在和影响。将通过理论研究、计算机模拟以及现场和实验室数据分析来回答与五个主要研究主题有关的问题：雨滴与其预期终端速度的偏差、垂直分层介质中的辐射传输、使用高分辨率和短脉冲数据的雷达后向散射的相干性、降水的时间和空间相关性及其对尺度的依赖、以及气压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.
