NOAA 报告 2022 年大西洋飓风季正式结束

美国国家海洋和大气管理局表示,今年的独特季节是由风暴罕见的季中暂停所决定的,科学家初步认为这是由于风切变增加和大西洋上空高空大气湿度受到抑制造成的。

据美国国家海洋和大气管理局 (NOAA) 称,2022 年大西洋飓风季节于 11 月 30 日正式结束,总共产生了 14 场命名风暴,其中 8 场成为飓风。

尽管今年的飓风季节已经结束,“伊恩、妮可和菲奥娜飓风的影响分别给佛罗里达州海岸和波多黎各带来了广泛破坏”,但在飓风季节结束后很长一段时间内,人们仍将继续感受到飓风伊恩、妮可和菲奥娜的影响。结束了,”NOAA 在 11 月 29 日的一份新闻稿中指出。 

总共,这个飓风季节产生了 14 场命名风暴(风速 39 英里/小时或以上),其中 8 场升级为飓风(风速 74 英里/小时或以上),另外 2 场增强为强飓风,风速达到 111 英里/小时或以上。平均飓风季节有 14 场命名风暴、7 场飓风和 3 场主要飓风。

2022 年飓风季共有 3 次飓风在美国大陆沿岸登陆。

飓风伊恩首先以 4 级风暴的形式在佛罗里达州科斯塔岛登陆,随后又以 1 级风暴的形式在南卡罗来纳州乔治敦登陆。飓风伊恩为 4 级飓风,最大持续风速为 150 英里/小时,与登陆美国的第五强飓风并列。飓风妮可在佛罗里达州哈钦森岛北部登陆,为 1 级飓风。 

飓风菲奥娜在美国本土以外的地区登陆,等级为 1 级,靠近波多黎各蓬塔托孔。  

美国商务部长吉娜·雷蒙多 (Gina Raimondo) 表示:“赞扬 NOAA 敬业的科学家、飓风搜寻飞行员和预报员,他们辛勤工作,帮助美国社区提高飓风抵御能力,并为本飓风季节和未来几年的影响做好气候准备。” 

美国国家海洋和大气管理局表示,今年的独特季节是由风暴罕见的季中暂停所决定的,科学家初步认为这是由于风切变增加和大西洋上空高空大气湿度受到抑制造成的。

经过八月的平静期后,九月的活动开始活跃,出现了七场命名风暴,其中包括本季出现的两大飓风“艾奥纳”和“伊恩”。该季节还包括罕见的季末风暴,飓风妮可于 11 月 10 日沿佛罗里达州东海岸登陆。

“NOAA 国家气象局及其国家飓风中心的预报员在本季度发布了较早的预报,其准确性不断提高,”NOAA 管理员 Rick Spinrad 博士说。“这些改进的预测加上关键的 NOAA 数据和服务无疑可以更好地保护生命和财产。”

2023 年飓风季节将于 6 月 1 日正式开始。美国国家气象局 (National Weather Service) 下属部门 NOAA 气候预测中心将于 5 月发布 2023 年初步季节展望。

NOAA Reports 2022 Atlantic Hurricane Season’s Official End

The NOAA said the unique season this year was defined by a rare mid-season pause in storms that scientists preliminarily believe was caused by increased wind shear and suppressed atmospheric moisture high over the Atlantic Ocean.

The 2022 Atlantic hurricane season officially ends on Nov. 30, producing a total of 14 named storms, eight of which became hurricanes, according to the National Oceanic and Atmospheric Administration (NOAA).

Despite the end of this year’s hurricane season, “the impact of Hurricanes Ian, Nicole and Fiona—which brought extensive damage to Florida’s coast and Puerto Rico, respectively—will continue to be felt long after the season is over,” the NOAA noted in a Nov. 29 release. 

In total, this hurricane season produced 14 named storms (winds of 39 mph or greater), of which eight became hurricanes (winds of 74 mph or greater) and two intensified to major hurricanes with winds reaching 111 mph or greater. An average hurricane season has 14 named storms, seven hurricanes and three major hurricanes.

The 2022 season saw three hurricane landfalls along the coast of the U.S. mainland.

Hurricane Ian made landfall first as a Category 4 storm in Cayo Costa, Florida, and again as a Category 1 in Georgetown, South Carolina. As a Category 4 with 150 mph maximum sustained winds, Hurricane Ian tied for the fifth-strongest hurricane ever to make landfall in the U.S. Hurricane Nicole made landfall as a Category 1 in north Hutchinson Island, Florida. 

Hurricane Fiona made landfall outside of the mainland U.S. as a Category 1 near Punta Tocon, Puerto Rico.  

“I commend NOAA’s dedicated scientists, hurricane hunter pilots and forecasters who worked diligently to help American communities become hurricane resilient and climate-ready for the impacts of this hurricane season and the years to come,” said Secretary of Commerce Gina Raimondo. 

The NOAA said the unique season this year was defined by a rare mid-season pause in storms that scientists preliminarily believe was caused by increased wind shear and suppressed atmospheric moisture high over the Atlantic Ocean.

After a quiet period in August, activity ramped up in September with seven named storms, including the two major hurricanes—Fiona and Ian—seen this season. The season also included a rare late-season storm with Hurricane Nicole making landfall on Nov. 10 along the east coast of Florida.

“Forecasters at NOAA’s National Weather Service and its National Hurricane Center issued earlier forecasts with increasing accuracy this season,” said NOAA Administrator Rick Spinrad, Ph.D. “These improved forecasts coupled with critical NOAA data and services undoubtedly led to the better protection of life and property.”

The 2023 hurricane season will officially begin on June 1.  NOAA’s Climate Prediction Center, a division of the National Weather Service, will issue its initial 2023 seasonal outlook in May.
