The 1940 Atlantic hurricane season was a generally average period of tropical cyclogenesis in 1940. Though the season had no official bounds, most tropical cyclone activity occurred during August and September. Throughout the year, fourteen tropical cyclones formed, of which nine reached tropical storm intensity; six were hurricanes. None of the hurricanes reached major hurricane intensity. Tropical cyclones that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Because technologies such as satellite monitoring were not available until the 1960s, historical data on tropical cyclones from this period are often not reliable. As a result of a reanalysis project which analyzed the season in 2012, an additional hurricane was added to HURDAT. The year's first tropical storm formed on May 19 off the northern coast of Hispaniola. At the time, this was a rare occurrence, as only four other tropical disturbances were known to have formed prior during this period;〔 since then, reanalysis of previous seasons has concluded that there were more than four tropical cyclones in May before 1940. The season's final system was a tropical disturbance situated in the Greater Antilles, which dissipated on November 8. All three hurricanes in August brought flooding rainfall to areas of the United States. The first became the wettest tropical cyclone recorded in Louisiana history. The second hurricane impacted regions of the Southeastern United States, producing record precipitation and killing at least 52 people. Despite not making landfall, the third hurricane in August interacted with a stationary front over the Mid-Atlantic states, resulting in localized flooding and thus making the tropical cyclone the wettest in New Jersey history. This hurricane would also be the strongest in the hurricane season, with maximum sustained winds of 110 mph (175 km/h) and a minimum barometric pressure of 961 mbar (hPa; 28.39 inHg), making it a high-end Category 2 hurricane on the modern-day Saffir–Simpson hurricane wind scale. Activity decreased in September, though a damaging hurricane swept through areas of the Canadian Maritimes, resulting in large crop and infrastructural losses. Two tropical cyclones of at least tropical storm strength were recorded in October, though neither resulted in fatalities. Collectively, storms in the hurricane season caused 71 fatalities and $29.329 million in damages. The 1940 South Carolina hurricane, which swept through areas of the Southeastern United States in August, was the most damaging and deadly of the tropical cyclones. ==Storms== ImageSize = width:800 height:200 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/05/1940 till:01/01/1941 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/06/1940 Colors = id:canvas value:gray(0.88) id:GP value:red id:TD value:rgb(0.38,0.73,1) legend:Tropical_Depression_(TD)_=_<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_(118–153_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:10 align:left fontsize:S shift:(4,-4) anchor:till from:19/05/1940 till:25/05/1940 color:TS text:"One (TS)" from:03/08/1940 till:10/08/1940 color:C2 text:"Two (C2)" from:05/08/1940 till:14/08/1940 color:C2 text:"Three (C2)" from:26/08/1940 till:02/09/1940 color:C2 text:"Four (C2)" from:02/09/1940 till:07/09/1940 color:TD text:"Tropical depression" from:07/09/1940 till:17/09/1940 color:C2 text:"Five (C2)" barset:break from:10/09/1940 till:13/09/1940 color:TD text:"Tropical depression" from:18/09/1940 till:28/09/1940 color:TS text:"Six (TS)" from:22/09/1940 till:28/09/1940 color:C2 text:"Seven (C2)" from:09/10/1940 till:10/10/1940 color:TD text:"Tropical depression" from:14/10/1940 till:14/10/1940 color:TD text:"Tropical depression" from:20/10/1940 till:24/10/1940 color:C1 text:"Eight (C1)" from:24/10/1940 till:26/10/1940 color:TS text:"Nine (TS)" from:07/11/1940 till:08/11/1940 color:TD text:"Tropical depression" bar:Month width:15 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/05/1940 till:01/06/1940 text:May from:01/06/1940 till:01/07/1940 text:June from:01/07/1940 till:01/08/1940 text:July from:01/08/1940 till:01/09/1940 text:August from:01/09/1940 till:01/10/1940 text:September from:01/10/1940 till:01/11/1940 text:October from:01/11/1940 till:01/12/1940 text:November from:01/12/1940 till:01/01/1941 text:December TextData = pos:(570,30) text:"(From the" pos:(617,30) text:"Saffir–Simpson hurricane wind scale)" 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「1940 Atlantic hurricane season」の詳細全文を読む スポンサード リンク
