The 1995–96 South-West Indian Ocean cyclone season was a moderately active season that included Cyclone Bonita, which was the first known tropical cyclone to cross from the southern Indian Ocean into the southern Atlantic Ocean. Tropical activity lasted for about six months from the middle of November 1995 to early May 1996. The first storm, Intense Tropical Cyclone Agnielle, formed in the adjacent Australian basin on November 16 and later reached peak winds in the south-west Indian Ocean. The next named storm after Agnielle was Bonita, which formed in early January and killed 42 people. The basin was most active in February, with two tropical cyclones, or the equivalent of a minimal hurricane, as well as a severe tropical storm. The first of these three was Doloresse, which killed 67 people due to a shipwreck in the Comoros. The next storm was Cyclone Edwige, which caused heavy crop damage on Mauritius before looping along the east coast of Madagascar. In March, both Cyclone Flossy and Tropical Storm Guylianne passed near the Mascarene Islands, producing heavy rainfall and gusty winds. Tropical activity continued through April and May, with two tropical cyclones in the former month. In early April, Tropical Cyclone Hansella moved over the island of Rodrigues, dropping more rainfall in 24 hours than the average monthly total. Later, Itelle became a rare April intense tropical cyclone, but weakened before it approached St. Brandon island. The final storm of the season, Jenna, formed in the Australian region, briefly intensified into a minimal tropical storm in the south-west Indian Ocean, and proceeded to exit the basin on May 4 to end the season. In addition to the named storms, several tropical depressions were tracked, one of which in December dropped heavy rainfall on Réunion. ==Seasonal summary== ImageSize = width:945 height:210 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:01/11/1995 till:01/06/1996 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/11/1995 Colors = id:canvas value:gray(0.88) id:GP value:red id:TD value:rgb(0.38,0.73,1) legend:Tropical_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:17/11/1995 till:27/11/1995 color:IT text:"Daryl-Agnielle" from:28/12/1995 till:31/12/1995 color:TD text:"B2 (TD)" from:03/01/1996 till:15/01/1996 color:IT text:"Bonita" from:09/01/1996 till:12/01/1996 color:ST text:"Hubert-Coryna" from:10/02/1996 till:10/02/1996 color:TS text:"12S" from:12/02/1996 till:20/02/1996 color:ST text:"Doloresse" from:14/02/1996 till:17/02/1996 color:TS text:"15S" barset:break from:19/02/1996 till:29/02/1996 color:TC text:"Edwige" from:25/02/1996 till:05/03/1996 color:TC text:"Flossy" from:17/03/1996 till:25/03/1996 color:TS text:"Guylianne" from:02/04/1996 till:10/04/1996 color:TC text:"Hansella" from:06/04/1996 till:19/04/1996 color:IT text:"Itelle" from:01/05/1996 till:06/05/1996 color:TS text:"Jenna " bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/11/1995 till:01/12/1995 text:November from:01/12/1995 till:01/01/1996 text:December from:01/01/1996 till:01/02/1996 text:January from:01/02/1996 till:01/03/1996 text:February from:01/03/1996 till:01/04/1996 text:March from:01/04/1996 till:01/05/1996 text:April from:01/05/1996 till:01/06/1996 text:May TextData = pos:(569,23) text:"(For further details, please see" pos:(713,23) text:"scales)" During the season, the Météo-France office (MFR) on Réunion island issued warnings in tropical cyclones within the basin. The agency estimated intensity through the Dvorak technique, and warned on tropical cyclones in the region from the coast of Africa to 90° E, south of the equator. The Joint Typhoon Warning Center (JTWC), which is a joint United States Navy – United States Air Force task force, also issued tropical cyclone warnings for the southwestern Indian Ocean. The season was fairly active with ten tropical storms, one greater than average, although most storms were short-lived. Six of the storms reached tropical cyclone status, or maximum sustained winds of at least 120 km/h (75 mph), which is two more than average. Most cyclones dissipated within the tropics, in contrast to the norm of storms accelerating into higher latitudes. Throughout the season there were 82 days in which there was tropical activity.〔 Based on a list contributed by the nation of Seychelles, the storms were named in sequential order, starting with Agnielle. The rest of the names on the list were Jenna, Ketty, Lucia, Molly, Nadege, Odette, Paquerette, Rolina, Sylvianne, Talla, Vivienne, Walya, and Yoline. In addition to the named storms, the MFR tracked 11 tropical depressions or disturbances that did not intensify into a tropical storm. The agency did not issue any bulletins on eight of them. Of the remaining three, two formed in late December, and the other formed in mid-February. Tropical Depression B2, the longest-lasting of the depressions, formed after a month of activity. An area of convection developed in the Mozambique Channel, and the MFR believed it to be connected to the depression that formed on December 28 east of Madagascar. With a ridge to the east, the system tracked southward, but failed to intensify due to strong wind shear. While passing west of Réunion, the depression dropped heavy rainfall, totaling along the northern coast and about twice that amount in the mountainous interior. On December 31, the depression dissipated to the southwest of Réunion.〔 On February 10, the JTWC tracked Tropical Cyclone 12S into the basin as a weakening tropical depression, which quickly dissipated.〔 A few days later, the JTWC also tracked Tropical Cyclone 15S from February 14–17, which briefly intensified into a minimal tropical storm in the eastern portion of the basin.〔 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「1995–96 South-West Indian Ocean cyclone season」の詳細全文を読む スポンサード リンク
