微下击暴流风速潜势评估:进展与发展

Microburst windspeed potential assessment: progress and developments

Kenneth L. Pryor

摘要:

已经开发和评估了一套产品,以评估对流下击暴流对飞行中飞机的危害,这些危害来自当前一代GOES。现有的GOES微下击暴流产品套件采用探空仪计算对流下击暴流生成的有利环境剖面概念模型的基础上的风险。因此,设计了一种诊断性临近预报产品,即微下击暴流风速潜势指数,以推断有利微下击暴流环境的属性。此外,GOES-West成像仪微下击暴流算法采用波段3(上层水蒸气)、波段4(长波红外窗口)和分裂窗口波段5之间的亮温差异,该算法已被开发用于补充探测器衍生产品。本文提供了一个更新的评估的探测器MWPI和成像微下击暴流算法,提出了案例研究,证明有效的业务使用的微下击暴流产品,并提出了验证结果,为2008年对流季节在美国大平原和大盆地地区。

英文摘要:

A suite of products has been developed and evaluated to assess hazards presented by convective downbursts to aircraft in flight derived from the current generation of GOES. The existing suite of GOES microburst products employs the sounder to calculate risk based on conceptual models of favorable environmental profiles for convective downburst generation. Accordingly, a diagnostic nowcasting product, the Microburst Windspeed Potential Index, is designed to infer attributes of a favorable microburst environment. In addition, a GOES-West imager microburst algorithm that employs brightness temperature differences between band 3 (upper level water vapor), band 4 (longwave infrared window), and split window band 5 has been developed to supplement the sounder-derived products. This paper provides an updated assessment of the sounder MWPI and imager microburst algorithms, presents case studies demonstrating effective operational use of the microburst products, and presents validation results for the 2008 convective season over United States Great Plains and Great Basin regions.
