Heavy Rainfall Mechanisms During the 2008 Terrain-influenced Monsoon Rainfall Experiment (TiMREX)

2008年夏季以台湾为中心的地形影响季风降雨实验（TiMREX）收集了特殊观测数据，以提高对这个多山岛屿地形影响强降水系统及其所处季风环境的物理过程的理解。 该奖项将使研究人员能够对可能存在问题的rawinsonde数据进行质量控制检查，将这些校正后的数据与其他观测数据相结合，以创建更全面的网格分析，本研究的学术价值在于分析特殊的探空仪比对发射，并以探空仪为研究对象，相关偏差和辅助卫星和地基遥感、卫星和地基遥感以及探测偏差的先验知识，以减少TiMREX活动期间使用的几种不同大气探测系统进行的湿度测量的偏差。 然后，研究人员将对与暴雨产生有关的过程进行诊断研究，包括调查台湾上游和上空的降雨模式与流动阻塞的关系，调查TiMREX区域的大气边界层结构及其与上述降水模式的联系，以及在现场实验中使用探空网络诊断对流的性质。通过提高对机制的理解，研究将产生更广泛的影响（并最终预测）强降雨，特别是在东亚季风季节，更普遍地在热带和亚热带山区环境，包括美洲。 TiMREX气象数据集的质量控制版本将被传播，供更广泛的科学界访问和利用，并将支持研究生教育。

The Terrain-influenced Monsoon Rainfall Experiment (TiMREX), centered on Taiwan in the summer of 2008, collected special observations to improve understanding of the physical process associated with terrain-influenced heavy precipitation systems over this mountainous island and the monsoonal environment in which they are embedded. This award will allow researchers to implement quality control checks on potentially problematic rawinsonde data, combine these corrected data with other observations to create a more comprehensive gridded analysis, and then apply these data to investigate processes leading to heavy rainfall over and surrounding Taiwan.The Intellectual Merit of this research includes focus on analysis of special rawinsonde intercomparison launches with an eye toward sonde-dependent biases and ancillary satellite and ground-based remote , satellite and ground based remote sensing, and prior knowledge of sonde biases to reduce biases in moisture measurements taken by the several different atmospheric sounding systems used during the TiMREX campaign. The researchers will then conduct diagnostic studies of processes related to the production of heavy rainfall, including investigation of rainfall patterns upstream of and over Taiwan in relation to flow blocking, investigation of atmospheric boundary layer structure in the TiMREX region and its connection with aforementioned precipitation patterns, and use of the sounding network to diagnose properties of convection during the field experiment.Broader Impacts of the research will accrue through improved understanding of mechanisms (and ultimately prediction) of heavy rainfall, both specifically during the East Asian monsoon season and more generally in mountainous tropical and subtropical environments including those found in the Americas. A quality-controlled version of the TiMREX meteorological dataset will be disseminated for access and exploitation by the broader scientific community, and graduate student education will be supported.
