微下击暴流风速潜势评估：进展和最新发展
Microburst windspeed potential assessment: progress and recent developments
摘要：
最近的测试和验证发现，GOES微下击暴流产品在评估和短期预测下击暴流潜力和相关阵风量级方面是有效的。两种产品，即GOES探测器微下击暴流风速潜势指数和多谱GOES成像仪产品，已证明具有评估下击暴流潜势的能力。每个微下击暴流产品由一组预测变量组成，这些预测变量生成预期微下击暴流风险的输出。本文对探空仪和成像仪微下击暴流产品进行了比较，指出了各自在临近预报中的优势。最新的评估的探测器MWPI和成像微下击暴流产品，案例研究表明有效的业务使用的微下击暴流产品，并验证结果为2009年对流季节在美国大平原。
英文摘要：
Recent testing and validation have found that the GOES microburst products are effective in the assessment and short-term forecasting of downburst potential and associated wind gust magnitude. Two products, the GOES sounder Microburst Windspeed Potential Index and the multispectral GOES imager product have demonstrated capability in downburst potential assessment. Each microburst product consists of a set of predictor variables that generates output of expected microburst risk. This paper compares and contrasts the sounder and imager microburst products and outlines the advantages of each product in the nowcasting process. An updated assessment of the sounder MWPI and imager microburst products, case studies demonstrating effective operational use of the microburst products, and validation results for the 2009 convective season over United States Great Plains is presented.
