The 2004 Pacific typhoon season has no official bounds; it ran year-round in 2004, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November.〔http://www.typhoon2000.ph/garyp_mgtcs/may03sum.txt 〕 These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 2004 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin are assigned a name by the Tokyo Typhoon Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names. The 2004 season was a very active season. 29 storms were named in this year and 19 of them reached typhoon intensity. The accumulated cyclone energy (ACE) index of this season amounted to 60% above the normal level for Pacific typhoon seasons, at 464. This makes 2004 season the third most active season in recorded history, only after 1997 and 1992.〔https://www.tropicalstormrisk.com/docs/TSRNWP2004Verification.pdf〕 ==Timeline== ImageSize = width:855 height:230 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:2 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/02/2004 till:01/01/2005 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/02/2004 Colors = id:canvas value:gray(0.88) id:GP value:red id:TD value:rgb(0.38,0.73,1) legend:Tropical_Depression_(TD)_=_<62_km/h_(<39_mph) id:TS value:rgb(0,0.98,0.96) legend:Tropical_Storm_(TS)_=_63-88_km/h_(39-54_mph) id:ST value:rgb(0.80,1,1) legend:Severe_Tropical_Storm_(STS)_=_89-117_km/h_(55-73_mph) id:TY value:rgb(0.99,0.69,0.6) legend:Typhoon_(TY)_=_>118_km/h_(>74_mph) Backgroundcolors = canvas:canvas BarData = barset:Hurricane bar:Month PlotData= barset:Hurricane width:10 align:left fontsize:S shift:(4,-4) anchor:till from:10/02/2004 till:19/02/2004 color:TD text:"Ambo" from:14/03/2004 till:23/03/2004 color:TS text:"Butchoy" from:02/04/2004 till:15/04/2004 color:TY text:"Sudal" from:13/05/2004 till:21/05/2004 color:TY text:"Nida" from:14/05/2004 till:18/05/2004 color:TS text:"05W" from:15/05/2004 till:22/05/2004 color:ST text:"Omais" from:04/06/2004 till:11/06/2004 color:TY text:"Conson" from:05/06/2004 till:15/06/2004 color:ST text:"Chanthu" from:11/06/2004 till:21/06/2004 color:TY text:"Dianmu" from:21/06/2004 till:04/07/2004 color:TY text:"Mindulle" barset:break from:24/06/2004 till:04/07/2004 color:TY text:"Tingting" from:12/07/2004 till:16/07/2004 color:TS text:"Kompasu" from:24/07/2004 till:02/08/2004 color:TY text:"Namtheun" from:26/07/2004 till:27/07/2004 color:TS text:"Unnamed" from:02/08/2004 till:05/08/2004 color:TS text:"Malou" from:02/08/2004 till:09/08/2004 color:TY text:"Meranti" from:06/08/2004 till:15/08/2004 color:TY text:"Rananim" from:06/08/2004 till:07/08/2004 color:TD text:"TD" from:10/08/2004 till:13/08/2004 color:TS text:"Malakas" from:13/08/2004 till:20/08/2004 color:TY text:"Megi" barset:break from:17/08/2004 till:31/08/2004 color:TY text:"Chaba" from:17/08/2004 till:26/08/2004 color:TY text:"Aere" from:25/08/2004 till:28/08/2004 color:TD text:"21W" from:26/08/2004 till:08/09/2004 color:TY text:"Songda" from:04/09/2004 till:08/09/2004 color:ST text:"Sarika" from:08/09/2004 till:11/09/2004 color:TD text:"TD" from:10/09/2004 till:13/09/2004 color:TS text:"Haima" from:15/09/2004 till:17/09/2004 color:TD text:"Pablo" from:15/09/2004 till:16/09/2004 color:TD text:"TD" from:18/09/2004 till:28/09/2004 color:TY text:"Meari" barset:break from:29/09/2004 till:10/10/2004 color:TY text:"Ma-on" from:10/10/2004 till:20/10/2004 color:TY text:"Tokage" from:13/10/2004 till:26/10/2004 color:TY text:"Nock-ten" from:13/11/2004 till:26/11/2004 color:TY text:"Muifa" from:22/11/2004 till:23/11/2004 color:TS text:"Merbok" from:27/11/2004 till:30/11/2004 color:TD text:"Winnie" from:28/11/2004 till:04/12/2004 color:TY text:"Nanmadol" from:09/12/2004 till:20/12/2004 color:TS text:"Talas" from:17/12/2004 till:22/12/2004 color:TS text:"Noru" bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/02/2004 till:01/03/2004 text:February from:01/03/2004 till:01/04/2004 text:March from:01/04/2004 till:01/05/2004 text:April from:01/05/2004 till:01/06/2004 text:May from:01/06/2004 till:01/07/2004 text:June from:01/07/2004 till:01/08/2004 text:July from:01/08/2004 till:01/09/2004 text:August from:01/09/2004 till:01/10/2004 text:September from:01/10/2004 till:01/11/2004 text:October from:01/11/2004 till:01/12/2004 text:November from:01/12/2004 till:01/01/2005 text:December 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「2004 Pacific typhoon season」の詳細全文を読む スポンサード リンク
