The 2003–04 South Pacific cyclone season was a below-average season with only three tropical cyclones occurring within the South Pacific to the east of 160°E. The season officially ran from November 1, 2003 to April 30, 2004 with the first disturbance of the season forming on December 4 and the last disturbance dissipating on April 23.〔An average season has nine tropical cyclones, about half of which become severe tropical cyclones.〕〔RSMC Nadi warns on systems in the South Pacific which is located from the equator to 25°S and from 160°E to 120°W. TCWC Wellington warns on systems from 25°S to 40°S and from 160°E to 120°W〕 This is the period of the year when most tropical cyclones form within the South Pacific Ocean.〔(【引用サイトリンク】url=http://www.webcitation.org/query?id=1242952602408859 )〕 During the season at least 16 people were killed from tropical disturbances whilst overall damage was estimated at $ (2004 USD; $ USD). The most damaging tropical disturbance was Cyclone Heta which caused at least $ (2004 USD; $ USD) in damage to six different countries and left three dead. The deadliest tropical disturbance of the season was Tropical Depression 10F, which was responsible for eleven deaths and caused $ (2004 USD) in damage. Cyclone Ivy also caused 2 deaths and caused $ (2004 USD; $ USD) worth of damage to Vanuatu.〔 As a result of the impacts caused by Heta and Ivy, the names were retired from the tropical cyclone naming lists.〔 Within the South Pacific, tropical cyclones are monitored by the Regional Specialized Meteorological Center (RSMC) in Nadi, Fiji, and the Tropical Cyclone Warning Center (TCWC) in Wellington, New Zealand. RSMC Nadi attaches a number and an F suffix to tropical disturbances that form in or move into the South Pacific. The United States Joint Typhoon Warning Center (JTWC) issues unofficial warnings within the South Pacific, designating tropical cyclones with a number and a P suffix. RSMC Nadi and TCWC Wellington both use the Australian Tropical Cyclone Intensity Scale, and measure windspeeds over a period of ten minutes, while the JTWC measures sustained winds over a period of one minute and uses the Saffir–Simpson Hurricane Scale. ==Seasonal summary== 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:01/12/2003 till:01/05/2004 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/12/2003 Colors = id:canvas value:gray(0.88) id:GP value:red id:TI value:rgb(0.5,0.8,1) legend:Tropical_Disturbance_=_<48_km/h_(<30 mph) id:TE value:rgb(0.25,0.65,1) legend:Tropical_Depression_=_48-63_km/h_(30-39_mph) id:C1 value:rgb(0,0.98,0.96) legend:Category_1_=_63-87_km/h_(39-54_mph) id:C2 value:rgb(0.80,1,1) legend:Category_2_=_88-142_km/h_(55-74_mph) id:C3 value:rgb(1,1,0.80) legend:Category_3_=_143-158-km/h_(75-98_mph) id:C4 value:rgb(1,0.76,0.25) legend:Category_4_=_159-204_km/h_(99-127_mph) id:C5 value:rgb(1,0.38,0.38) legend:Category_5_=_≥205_km/h_(≥128_mph) Backgroundcolors = canvas:canvas BarData = barset:Hurricane bar:Month PlotData= barset:Hurricane width:10 align:left fontsize:S shift:(4,-4) anchor:till from:04/12/2003 till:06/12/2003 color:TE text:"01F" from:16/12/2003 till:20/12/2003 color:TE text:"02F" from:25/12/2003 till:07/01/2004 color:C5 text:"Heta" from:21/02/2004 till:02/03/2004 color:C4 text:"Ivy" from:20/03/2004 till:22/03/2004 color:TE text:"06F" from:23/03/2004 till:26/03/2004 color:C2 text:"Grace" from:28/03/2004 till:01/04/2004 color:TE text:"08F" barset:break from:01/04/2004 till:03/04/2004 color:TE text:"09F" from:04/04/2004 till:09/04/2004 color:TE text:"10F" from:07/04/2004 till:07/04/2004 color:TE text:"11F" from:07/04/2004 till:13/04/2004 color:TE text:"12F" from:12/04/2004 till:13/04/2004 color:TE text:"13F" from:18/04/2004 till:19/04/2004 color:TI text:"14F" from:21/04/2004 till:24/04/2004 color:TI text:"15F" bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/12/2003 till:01/01/2004 text:December from:01/01/2004 till:01/02/2004 text:January from:01/02/2004 till:28/02/2004 text:February from:01/03/2004 till:01/04/2004 text:March from:01/04/2004 till:01/05/2004 text:April 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「2003–04 South Pacific cyclone season」の詳細全文を読む スポンサード リンク
