The 1887 Atlantic hurricane season was the third most active Atlantic hurricane season on record, tying with the 1995, 2010, 2011, and the 2012 seasons for third most number of storms. The season ran through the summer and almost all of the fall in 1887, and was surpassed in total number of tropical cyclones only by the seasons of 1933 and the record-breaking 2005. The 1887 season saw tropical activity as early as May, and as late as December. 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 may not be comprehensive. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. Of the known 1887 cyclones, Tropical Storm One and Tropical Storm Three were first documented in 1996 by Jose Fernandez-Partagas and Henry Diaz. They also proposed large alterations to the known tracks of several of the other 1887 storms.〔Partagas, J.F. and H.F. Diaz, 1996a "A reconstruction of historical Tropical Cyclone frequency in the Atlantic from documentary and other historical sources Part III: 1881-1890" Climate Diagnostics Center, NOAA, Boulder, CO〕 Later re-analysis led to the known duration of Hurricane Six, and also that of Hurricane Fifteen, being increased. Ten of the season's nineteen known storms attained hurricane status. However, only two of these storms became major hurricanes, with sustained winds of over 111 mph (179 km/h); the strongest reached peak winds of 125 mph (205 km/h), with a minimum barometric pressure of off the East Coast of the United States in late August. Only a few of the storms during the 1887 season did not impact land, but there was a low number of deaths. ==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:01/05/1887 till:01/01/1888 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/05/1887 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)_(TD) id:TS value:rgb(0,0.98,0.96) legend:Tropical_Storm_=_39–73_mph_(63–117 km/h)_(TS) id:C1 value:rgb(1,1,0.80) legend:Category_1_=_74–95_mph_(119–153_km/h)_(C1) id:C2 value:rgb(1,0.91,0.46) legend:Category_2_=_96–110_mph_(154–177_km/h)_(C2) id:C3 value:rgb(1,0.76,0.25) legend:Category_3_=_111–130_mph_(178–209-km/h)_(C3) id:C4 value:rgb(1,0.56,0.13) legend:Category_4_=_131–155_mph_(210–249_km/h)_(C4) id:C5 value:rgb(1,0.38,0.38) legend:Category_5_=_≥157_mph_(≥252_km/h)_(C5) Backgroundcolors = canvas:canvas BarData = barset:Hurricane bar:Month PlotData= barset:Hurricane width:11 align:left fontsize:S shift:(4,-4) anchor:till from:15/05/1887 till:20/05/1887 color:TS text:"One (TS)" from:17/05/1887 till:21/05/1887 color:TS text:"Two (TS)" from:11/06/1887 till:14/06/1887 color:TS text:"Three (TS)" from:20/07/1887 till:28/07/1887 color:C2 text:"Four (C2)" from:30/07/1887 till:08/08/1887 color:TS text:"Five (TS)" from:14/08/1887 till:23/08/1887 color:C3 text:"Six (C3)" from:18/08/1887 till:27/08/1887 color:C3 text:"Seven (C3)" barset:break from:01/09/1887 till:07/09/1887 color:C2 text:"Eight (C2)" from:11/09/1887 till:22/09/1887 color:C2 text:"Nine (C2)" from:14/09/1887 till:18/09/1887 color:C1 text:"Ten (C1)" from:06/10/1887 till:09/10/1887 color:TS text:"Eleven (TS)" from:08/10/1887 till:09/10/1887 color:TS text:"Twelve (TS)" from:09/10/1887 till:22/10/1887 color:C1 text:"Thirteen (C1)" from:10/10/1887 till:12/10/1887 color:C1 text:"Fourteen (C1)" barset:break from:15/10/1887 till:19/10/1887 color:C2 text:"Fifteen (C2)" from:30/10/1887 till:01/11/1887 color:TS text:"Sixteen (TS)" from:27/11/1887 till:04/12/1887 color:C1 text:"Seventeen (C1)" from:04/12/1887 till:10/12/1887 color:C1 text:"Eighteen (C1)" from:07/12/1887 till:12/12/1887 color:TS text:"Nineteen (TS)" bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/05/1887 till:01/06/1887 text:May from:01/06/1887 till:01/07/1887 text:June from:01/07/1887 till:01/08/1887 text:July from:01/08/1887 till:01/09/1887 text:August from:01/09/1887 till:01/10/1887 text:September from:01/10/1887 till:01/11/1887 text:October from:01/11/1887 till:01/12/1887 text:November from:01/12/1887 till:01/01/1888 text:December 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「1887 Atlantic hurricane season」の詳細全文を読む スポンサード リンク
