The 1891 Atlantic hurricane season ran through the summer and the early winter of 1891. The season had ten tropical cyclones, seven of which became hurricanes including one which became a major Category 3 hurricane. However, in the absence of modern satellite and other remote-sensing technologies, only cyclones that affected populated land areas or encountered ships at sea are currently known, so the actual total could be higher. An undercount bias of zero to four tropical cyclones per year between 1886 and 1910 has been estimated. The tracks of four of the ten known 1891 Atlantic cyclones were revised in 1996 by Jose Fernandez-Partagas. Following re-analysis in 2003, two storms previously considered distinct are now regarded as a single system, Tropical Storm 8. A number of other storms from 1891 were considered for inclusion in the Atlantic hurrice database, HURDAT, but are currently excluded due to a lack of evidence of tropical storm intensity. ==Timeline== 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:01/07/1891 till:01/12/1891 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/07/1891 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_(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:10 align:left fontsize:S shift:(4,-4) anchor:till from:03/07/1891 till:08/07/1891 color:C1 text:"One (C1)" from:17/08/1891 till:29/08/1891 color:C1 text:"Two (C1)" from:18/08/1891 till:25/08/1891 color:C3 text:"Three (C3)" from:02/09/1891 till:08/09/1891 color:C2 text:"Four (C2)" from:16/09/1891 till:26/09/1891 color:C2 text:"Five (C2)" barset:break from:29/09/1891 till:05/10/1891 color:C2 text:"Six (C2)" from:04/10/1891 till:08/10/1891 color:TS text:"Seven (TS)" from:07/10/1891 till:09/10/1891 color:TS text:"Eight (TS)" from:12/10/1891 till:20/10/1891 color:C1 text:"Nine (C1)" from:03/11/1891 till:06/11/1891 color:TS text:"Ten (TS)" bar:Month width:15 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/07/1891 till:01/08/1891 text:July from:01/08/1891 till:01/09/1891 text:August from:01/09/1891 till:01/10/1891 text:September from:01/10/1891 till:01/11/1891 text:October from:01/11/1891 till:01/12/1891 text:November TextData = pos:(570,30) text:"(From the" pos:(617,30) text:"Saffir–Simpson Hurricane 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「1891 Atlantic hurricane season」の詳細全文を読む スポンサード リンク
