英国的首个秋季命名风暴将在本周末给全国带来更强的风力。气象局表示,风暴奥斯汀的阵风在沿海地区可能达到每小时80英里(129公里),相当于五级萨菲尔-辛普森风力等级中的一级飓风。此前预计的风力为每小时70英里。
Britain’s first named storm of the autumn will be stronger than previously thought when it sweeps across the country later this week. Gusts from Storm Austen may reach 80 miles (129 kilometers) per hour in coastal areas, equivalent to a Category 1 hurricane on the five-step Saffir-Simpson scale, according to the UK Met Office. That’s up from 70 mph expected previously.
风暴将于本周四晚间至周五,给英国及西北欧带来强风和大雨。英国南部地区及威尔士已发布强风警报,爱尔兰大部分地区则有黄色暴雨警报。荷兰以及西班牙和法国北部沿海地区也面临天气警报。
The storm will bring damaging winds and heavy rain to Britain and northwest Europe late Thursday and into Friday. Wind warnings have been issued for southern parts of England and Wales, and a yellow rain warning is in place for much of Ireland. The Netherlands and northern coastal regions of Spain and France also face weather alerts.
强风可能导致交通瘫痪并倒塌电力线路,英国境内的阵风预计最高可达每小时60英里。同时,强风有望通过提升风电发电量为电力市场带来缓解,但也可能引发削减,即因传输容量有限,在强风发电期间风电场需减产,并在此期间获得补偿。
High winds could snarl transportation and topple power lines, with inland gusts forecast at up to 60 miles an hour in the UK. They could also bring some relief to power markets by boosting wind energy output. Yet with that comes the risk of curtailment, when limited transmission capacity means wind farms are paid to reduce production during periods of strong generation.
据大气科学机构大气G2的气象学家安德鲁·佩德里尼(Andrew Pedrini)表示,削减现象可能在西北欧范围内发生,包括英国和爱尔兰。
Curtailments are possible across northwest Europe, including the UK and Ireland, said Andrew Pedrini, a meteorologist at Atmospheric G2.
奥斯汀正在从纽芬兰附近的低压区形成,并与异常活跃的急流相互作用,这使得风暴在接近西欧时得以增强,尽管其确切路径仍不明确。
Austen is forming from an area of low pressure near Newfoundland that’s come up against an unusually active jet stream. That’s allowing the storm to strengthen as it approaches western Europe, though its exact path remains unclear.
部分天气模型预测出现“爆炸性气旋爆发”,即中心气压急剧下降的现象,这会加剧风暴的风力和降雨量。若出现此情况,则意味着奥斯汀是一场“迅速增强、强劲的风暴”,具有毁灭性潜力,佩德里尼表示。
Some weather models point to a sharp drop in central air pressure known as “explosive cyclogenesis,” which can amplify a storm’s winds and rainfall. If that occurs, it would be a sign that Austen is a “rapidly intensifying, potent storm” with destructive potential, Pedrini said.
另一个暴风雨般的低压系统预计将在本周末紧随“奥斯汀”而至,横扫苏格兰并将大雨和大雪推向北欧地区。根据天气模型和气象学家的分析,随后一个高压脊将给欧洲大部分地区带来更平静、更温暖的天气。
Another stormy low-pressure system is set to follow Austen this weekend, tracking across Scotland and pushing heavy rain and snow into the Nordic region. A ridge of high pressure will subsequently bring calmer, warmer conditions to much of Europe, according to weather models and analysis from meteorologists.
