The 2011–12 South-West Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It began on November 15, 2011, and ended on April 30, 2012, with the exception for Mauritius and the Seychelles, for which it ended on May 15, 2012. These dates conventionally delimit the period of each year when most tropical cyclones form in the region; however, Severe Tropical Storm Kuena developed in early June after the season had officially ended. The basin is defined as the area west of 90°E and south of the Equator in the Indian Ocean, which includes the waters around Madagascar westward to the east coast of Africa. Tropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion. ==Timeline== ImageSize = width:900 height:205 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:01/12/2011 till:01/07/2012 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/12/2011 Colors = id:canvas value:gray(0.88) id:GP value:red id:ZD value:rgb(0.5,0.8,1) legend:Zone_of_Disturbed_Weather/Tropical_Disturbance id:TD value:rgb(0.38,0.73,1) legend:Tropical_Depression/Subtropical_Depression id:TS value:rgb(0,0.98,0.96) legend:Moderate_Tropical_Storm id:ST value:rgb(0.80,1,1) legend:Severe_Tropical_Storm id:TC value:rgb(1,1,0.80) legend:Tropical_Cyclone id:IT value:rgb(1,0.76,0.25) legend:Intense_Tropical_Cyclone id:VI value:rgb(1,0.38,0.38) legend:Very_Intense_Tropical_Cyclone Backgroundcolors = canvas:canvas BarData = barset:Hurricane bar:Month PlotData= barset:Hurricane width:11 align:left fontsize:S shift:(4,-4) anchor:till from:04/12/2011 till:07/12/2011 color:TS text:"Alenga" from:06/12/2011 till:16/12/2011 color:TD text:"02" from:19/12/2011 till:23/12/2011 color:TD text:"03" from:28/12/2011 till:04/01/2012 color:TC text:"Benilde" from:05/01/2012 till:10/01/2012 color:TS text:"Chanda" from:10/01/2012 till:18/01/2012 color:TD text:"Dando" from:17/01/2012 till:22/01/2012 color:ST text:"Ethel" barset:break from:17/01/2012 till:28/01/2012 color:IT text:"Funso" from:07/02/2012 till:22/02/2012 color:IT text:"Giovanna" from:14/02/2012 till:22/02/2012 color:TS text:"Hilwa" from:25/02/2012 till:12/03/2012 color:ST text:"Irina" from:29/02/2012 till:03/03/2012 color:TD text:"12" from:08/03/2012 till:11/03/2012 color:ST text:"Koji–Joni" from:03/06/2012 till:08/06/2012 color:TS text:"Kuena" bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/12/2011 till:01/01/2012 text:December from:01/01/2012 till:01/02/2012 text:January from:01/02/2012 till:01/03/2012 text:February from:01/03/2012 till:01/04/2012 text:March from:01/04/2012 till:01/05/2012 text:April from:01/05/2012 till:01/06/2012 text:May from:01/06/2012 till:01/07/2012 text:June TextData = pos:(569,23) text:"(For further details, please see" pos:(713,23) text:"scales)" 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「2011–12 South-West Indian Ocean cyclone season」の詳細全文を読む スポンサード リンク
