1929 Atlantic hurricane season (original) (raw)

dbo:abstract

The 1929 Atlantic hurricane season was among the least active hurricane seasons in the Atlantic on record – featuring only five tropical cyclones. Of these five tropical systems, three of them intensified into a hurricane, with one strengthening further into a major hurricane (Category 3 or higher on the Saffir–Simpson hurricane wind scale). The first tropical cyclone of the season developed in the Gulf of Mexico on June 27. Becoming a hurricane on June 28, the storm struck Texas, bringing strong winds to a large area. Three fatalities were reported, while damage was conservatively estimated at 675,000(1929USD).Thesecondstorm,nicknamedtheBahamashurricane,developednorthoftheLesserAntilles.Itwasthemostintensetropicalcycloneoftheseason,peakingasaCategory4hurricaneontheSaffir–Simpsonhurricanewindscalewithmaximumsustainedwindsof155mph(250km/h)andaminimumbarometricpressureof924mbar(27.3inHg).ThestormmovedthroughtheBahamasatthisintensityandlaterstruckFloridawhileslightlyweaker.Overall,thishurricaneresultedin59deathsandatleast675,000 (1929 USD). The second storm, nicknamed the Bahamas hurricane, developed north of the Lesser Antilles. It was the most intense tropical cyclone of the season, peaking as a Category 4 hurricane on the Saffir–Simpson hurricane wind scale with maximum sustained winds of 155 mph (250 km/h) and a minimum barometric pressure of 924 mbar (27.3 inHg). The storm moved through the Bahamas at this intensity and later struck Florida while slightly weaker. Overall, this hurricane resulted in 59 deaths and at least 675,000(1929USD).Thesecondstorm,nicknamedtheBahamashurricane,developednorthoftheLesserAntilles.Itwasthemostintensetropicalcycloneoftheseason,peakingasaCategory4hurricaneontheSaffir–Simpsonhurricanewindscalewithmaximumsustainedwindsof155mph(250km/h)andaminimumbarometricpressureof924mbar(27.3inHg).ThestormmovedthroughtheBahamasatthisintensityandlaterstruckFloridawhileslightlyweaker.Overall,thishurricaneresultedin59deathsandatleast9.31 million in damage. The next three tropical cyclones did not impact land, with the last transitioning into an extratropical cyclone on October 22. Until the Atlantic hurricane reanalysis project researched the season in 2010, the final two systems were considered the same tropical cyclone. The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 48, below the 1921–1930 average of 76.6. ACE is a metric used to express the energy used by a tropical cyclone during its lifetime. Therefore, a storm with a longer duration will have high values of ACE. It is only calculated at six-hour increments in which specific tropical and subtropical systems are either at or above sustained wind speeds of 39 mph (63 km/h), which is the threshold for tropical storm intensity. Thus, tropical depressions are not included here. (en)
1929年大西洋飓风季的活跃度很低，一共只形成五个热带气旋，其中三个增强成飓风，一个达到大型飓风标准，即达到现代萨菲尔-辛普森飓风等级的三级飓风或以上强度。全季首场风暴于6月27日在墨西哥湾成型，次日成为飓风后吹袭德克萨斯州，在大面积地区产生狂风，共造成三人死亡，经济损失保守估计为67.5万美元。第二场风暴人称，在小安的列斯群岛北面形成，最大持续风速高达每小时250公里，最低气压924毫巴（百帕，27.3英寸汞柱），达到萨菲尔-辛普森飓风等级下的四级飓风上限，是全季最强烈的热带气旋。风暴以最高强度经过巴哈马，再经小幅减弱后袭击佛罗里达州，共夺走59条人命，经济损失至少236万美元。之后形成的三个气旋都没有影响陆地，最后一个于10月22日转变成温带气旋。气象学界此前八十年里一直认为本季只有四个热带气旋，但经2010年的后认定最后一场风暴实际上是两个气旋。这年飓风季的活跃程度还经累积气旋能量指数反映出来，数值为48。大致来说，气旋能量指数通过飓风强度和持续时间计算，强度越高、持续时间越长的风暴，其指数也相应越高。 (zh)
