The 1987–88 South-West Indian Ocean cyclone season was a moderately active cyclone season, with nine named storms. Four of the storms attained tropical cyclone status, which is the equivalent of a minimal hurricane with 10 minute sustained winds of at least 120 km/h (75 mph). The seasonal activity was evenly dispersed, officially beginning on December 9 when the Météo-France office (MFR) on Réunion started tracking Tropical Storm Ariny. The storm crossed 90° E from the adjacent Australian basin, one of two storms in the season to do so along with Cyclone Ezenina. There were also two storms tracked unofficially by the Joint Typhoon Warning Center (JTWC) in November. Cyclone Filao was the most notable storm of the season, originating in late February off northern Madagascar. It ultimately struck Mozambique on March 1, where it killed about 100 people and left $10 million in damage (1988 USD). In January, both tropical storms Calidera and Doaza crossed Madagascar, the latter of which helped end a drought. Long-lasting Tropical Storm Hely also struck the country in March. The strongest cyclone of the season was Gasitao, which formed at the same time as Hely and attained peak winds of 150 km/h (95 mph). The season ended when Tropical Storm Iarisena dissipated northeast of Madagascar in the middle of May. ==Seasonal summary== ImageSize = width:1000 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:01/10/1987 till:01/06/1988 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/11/1987 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:31/10/1987 till:09/11/1987 color:TS text:"01S (TS)" from:21/11/1987 till:26/11/1987 color:TS text:"02S (TS)" from:09/12/1987 till:16/12/1987 color:ST text:"Ariny (STS)" from:24/12/1987 till:04/01/1988 color:TS text:"Benandro (MTS)" from:11/01/1988 till:21/01/1988 color:ST text:"Calidera (STS)" from:21/01/1988 till:01/02/1988 color:TC text:"Doaza (TC)" barset:break from:12/02/1988 till:18/02/1988 color:TC text:"Gwenda-Ezenina (TC)" from:23/02/1988 till:02/03/1988 color:TC text:"Filao (TC)" from:14/03/1988 till:25/03/1988 color:IT text:"Gasitao (ITC)" from:16/03/1988 till:02/04/1988 color:ST text:"Hely (STS)" from:06/05/1988 till:14/05/1988 color:TS text:"Iarisena (MTS)" bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/10/1987 till:01/11/1987 text:October from:01/11/1987 till:01/12/1987 text:November from:01/12/1987 till:01/01/1988 text:December from:01/01/1988 till:01/02/1988 text:January from:01/02/1988 till:01/03/1988 text:February from:01/03/1988 till:01/04/1988 text:March from:01/04/1988 till:01/05/1988 text:April from:01/05/1988 till:01/06/1988 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. Using satellite imagery from National Oceanic and Atmospheric Administration, 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 World Meteorological Organization recognized the MFR as a Regional Tropical Cyclone Advisory Centre in 1988, and would later label the agency as a Regional Specialized Meteorological Center in 1993. 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's nine named storms is equal to the long term average, while the five tropical cyclones – a storm attaining maximum sustained winds of at least – was slightly below average. The MFR considered the tropical cyclone year to begin on August 1 and continue to July 31 of the following year.〔 In addition to the storms classified by the MFR, the JTWC tracked two storms in November. The first, classified as Tropical Cyclone 01S, formed on November 1, about halfway between Diego Garcia and Sumatra. It formed as a cyclone pair, along with a tropical storm in the northern Indian Ocean that struck India. The storm moved west-southwestward, passing near Diego Garcia on November 3. The JTWC assessed peak 1 minute winds of 105 km/h (65 mph) on November 7, although the storm subsequently weakened and dissipated on November 9.〔 The other unofficial storm developed on November 24 near the eastern coast of Mozambique, classified as Tropical Cyclone 02S.〔 Moving to the southwest, it quickly intensified to reach winds of 75 km/h (45 mph). Early on November 25, the storm moved ashore near Quirimbas National Park in the northeastern portion of Mozambique, and it dissipated a day later. 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「1987–88 South-West Indian Ocean cyclone season」の詳細全文を読む スポンサード リンク
