The 1988–89 South-West Indian Ocean cyclone season was an active season that featured several storms moving near or over the Mascarene Islands or Madagascar. The eleven tropical storms was two greater than average, of which five became tropical cyclones – a storm with maximum sustained winds over 10 minutes of 120 km/h (75 mph) or greater. Storms were monitored by the Météo-France office (MFR) on Réunion island in an official capacity, as well as the American Joint Typhoon Warning Center (JTWC) on an unofficial base. The season began early with Moderate Tropical Storm Adelinina forming in early November, and continued through the middle of April. Adelinina was one of two storms to form in November, the other being Tropical Cyclone Barisaona which crossed from the adjacent Australian basin. After no activity in December, there were four storms in January, including the most notable of the season – Cyclone Firinga. The storm caused ₣1 billion (1989 francs, $157 million 1989 USD) in damage when it struck Réunion. Tropical Cyclone Calasanjy also formed in the month, causing heavy damage when it struck western Madagascar. Three storms formed in February, the second of which, Hanitra, also crossed from the Australian basin. This storm, as well as later Tropical Cyclone Krisy, were the strongest of the season, attaining peak 10 minute winds of 150 km/h (95 mph). Tropical Cyclone Jinabo was the first of three storms to form in quick succession in late March, the others being Krisy and Tropical Storm Lezissy. Jinabo originated off the east coast of Madagascar and dropped heavy rainfall on Réunion. Krisy took a similar track and passed within 100 km (60 mi) of Rodrigues and Mauritius, causing heavy crop damage. Lastly, Tropical Storm Lezissy merged with Krisy and dissipated on April 11 to end the season. ==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:01/10/1988 till:01/05/1989 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/10/1988 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:01/11/1988 till:08/11/1988 color:TS text:"Adelinina (MTS)" from:11/11/1988 till:20/11/1988 color:TC text:"Barisoana (TC)" from:06/01/1989 till:15/01/1989 color:TC text:"Calasanjy (TC)" from:10/01/1989 till:15/01/1989 color:TD text:"Dona (TD)" from:17/01/1989 till:26/01/1989 color:TC text:"Edme (TC)" from:24/01/1989 till:01/02/1989 color:TC text:"Firinga (TC)" barset:break from:17/02/1989 till:22/02/1989 color:ST text:"Gizela (STS)" from:19/02/1989 till:01/03/1989 color:TC text:"Leon-Hanitra (TC)" from:25/02/1989 till:01/03/1989 color:TS text:"Iana (MTS)" from:21/03/1989 till:31/03/1989 color:ST text:"Jinabo (STS)" from:26/03/1989 till:09/04/1989 color:TC text:"Krissy (TC)" from:04/04/1989 till:09/04/1989 color:TS text:"Lezissy (MTS)" bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/10/1988 till:01/11/1988 text:October from:01/11/1988 till:01/12/1988 text:November from:01/12/1988 till:01/01/1989 text:December from:01/01/1989 till:01/02/1989 text:January from:01/02/1989 till:01/03/1989 text:February from:01/03/1989 till:01/04/1989 text:March from:01/04/1989 till:01/05/1989 text:April 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. At the time, the World Meteorological Organization recognized the MFR as a Regional Tropical Cyclone Advisory Centre, 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 11 named storms is slightly above the long term average, while the five tropical cyclones – a storm attaining maximum sustained winds of at least – was the same as the long term average. There was an ongoing La Niña event in the middle of the season. 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 monitored by the MFR, the JTWC tracked a storm in March that formed off the west coast of Madagascar on March 7. It moved generally to the south or south-southeast, failing to intensify beyond 1 minute winds of 65 km/h (40 mph). After passing west of Madagascar, the storm dissipated on March 11. 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「1988–89 South-West Indian Ocean cyclone season」の詳細全文を読む スポンサード リンク
