The 1977 Atlantic hurricane season had the fewest tropical storms since the 1965 season. The season officially began on June 1, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first tropical depression of the season developed on June 13, 12 days after the start of the season, in the western Caribbean Sea. After a succession of three other tropical depressions, the first tropical storm of the season, Hurricane Anita, finally became a named storm on August 29 – the latest date since the satellite era began in the 1960s. Anita struck Mexico as a Category 5 hurricane on the Saffir–Simpson hurricane wind scale, bringing strong winds and heavy rainfall. At least 25,000 people were left homeless and 11 fatalities were reported. In addition to Anita, another notable tropical cyclone of this season was Hurricane Babe. The storm caused coastal flooding in southeastern Louisiana, resulting in $10 million (1977 USD) in damage. After moving inland, it spawned 14 tornadoes throughout Alabama, Louisiana, Mississippi, and South Carolina. In addition to Anita and Babe, five other tropical cyclones – hurricanes Clara, Dorothy, and Evelyn, as well as Tropical Storm Frieda and Tropical Depression Nine – left only minor impacts on land. Overall, the tropical cyclones of the season collectively caused 11 fatalities and at least $13 million in damage, excluding the remnants of Tropical Depression Nine, which led to 53 deaths and $203 million in losses due to flooding in the Southeastern United States, New Jersey, and New York. ==Season summary== ImageSize = width:800 height:200 PlotArea = top:10 bottom:70 right:20 left:20 Legend = columns:3 left:30 top:50 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/08/1977 till:01/01/1978 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/08/1977 Colors = id:canvas value:gray(0.88) id:GP value:red id:TD value:rgb(0.38,0.73,1) legend:Tropical_Depression_=_<39_mph_(0-62_km/h) id:TS value:rgb(0,0.98,0.96) legend:Tropical_Storm_=_39-73_mph_(63-117 km/h) id:C1 value:rgb(1,1,0.80) legend:Category_1_=_74-95_mph_(119-153_km/h) id:C2 value:rgb(1,0.91,0.46) legend:Category_2_=_96-110_mph_(154-177_km/h) id:C3 value:rgb(1,0.76,0.25) legend:Category_3_=_111-130_mph_(178-209-km/h) id:C4 value:rgb(1,0.56,0.13) legend:Category_4_=_131-155_mph_(210-249_km/h) id:C5 value:rgb(1,0.38,0.38) legend:Category_5_=_>=156_mph_(>=250_km/h) Backgroundcolors = canvas:canvas BarData = barset:Hurricane bar:Month PlotData= barset:Hurricane width:11 align:left fontsize:S shift:(4,-4) anchor:till from:29/08/1977 till:03/09/1977 color:C5 text:"Anita (C5)" from:03/09/1977 till:09/09/1977 color:C1 text:"Babe (C1)" from:05/09/1977 till:11/09/1977 color:C1 text:"Clara (C1)" from:22/09/1977 till:23/09/1977 color:TD text:"Four (TD)" from:26/09/1977 till:29/09/1977 color:C1 text:"Dorothy (C1)" from:03/10/1977 till:05/10/1977 color:TD text:"Six (TD)" barset:break from:13/10/1977 till:15/10/1977 color:C1 text:"Evelyn (C1)" from:16/10/1977 till:19/10/1977 color:TS text:"Frieda (TS)" from:04/11/1977 till:07/11/1977 color:TD text:"Nine (TD)" bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/08/1977 till:01/09/1977 text:August from:01/09/1977 till:01/10/1977 text:September from:01/10/1977 till:01/11/1977 text:October from:01/11/1977 till:01/12/1977 text:November TextData = pos:(570,30) text:"(From the" pos:(617,30) text:"Saffir-Simpson Hurricane Scale)" The Atlantic hurricane season officially began on June 1, 1977.〔 Activity began several days later with the formation of a tropical depression on June 13. Although 16 tropical depressions formed, it was a below average season because only 6 of them strengthened into tropical storms. In terms of named storms, this was the least active season since 1965.〔 Five of these attained hurricane status. In addition, one tropical cyclone eventually attained major hurricane status, which is Category 3 or higher on the Saffir–Simpson hurricane wind scale.〔 The inactivity was attributed to a El Niño that began developing in August. Three hurricanes and one tropical storm made landfall during the season, causing 11 deaths and $13 million in damage.〔 The last storm of the season, Tropical Depression Thirteen, dissipated on November 7, over three weeks before the official end of the season on November 30.〔 Tropical cyclogenesis in the 1977 Atlantic hurricane season began with the development of a tropical depression on June 13. Activity briefly halted, until two other tropical depression developed in the second half of July. A fourth tropical depression formed in early August. Later that month, Hurricane Anita developed on August 29. As September is the climatological peak of hurricane season, it was the most active month.〔 Five tropical cyclones developed, including two tropical depressions, and hurricanes Babe, Clara, and Dorothy.〔 There were also five tropical cyclone in October – three tropical depressions, Hurricane Evelyn, and Tropical Storm Frieda.〔 The final tropical cyclone of the season, Tropical Depression Nine, developed between the Greater Antilles and Bermuda on November 3 and dissipated by November 7. The season's activity was reflected with a cumulative accumulated cyclone energy (ACE) rating of 25, which was the lowest ACE value since 1946. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength. Subtropical storms are not included, therefore, the subtropical stage of Babe is omitted from the total ACE value. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1977 Atlantic hurricane season」の詳細全文を読む スポンサード リンク
