Sting jets in European windstorms can cause damaging winds and gusts, but the resolution of global ensemble prediction systems is too coarse to represent them. Here we describe the development of a tool applied to outputs from these systems that forecasters can use to identify favourable conditions for sting-jet occurrence several days ahead. Plots generated by this tool have been available to Met Office forecasters since autumn 2019, and we demonstrate its usefulness for storm Brendan from January 2020.

为预报员开发原型实时刺痛喷射前驱工具

欧洲风暴中的刺痛喷射会造成破坏性的风和阵风,但全球集合预测系统的分辨率太粗糙,无法代表它们。在这里,我们描述了一种应用于这些系统输出的工具的开发,预报员可以使用该工具来确定几天前发生刺喷射的有利条件。自 2019 年秋季以来,该工具生成的图已可供气象局预报员使用,我们证明了它对 2020 年 1 月起的风暴布伦丹的有用性。
