The 1989 North Indian Ocean cyclone season was a below-average season in annual cycle of tropical cyclone formation. The season has no official bounds but cyclones tend to form between April and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. There are two main seas in the North Indian Ocean—the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea to the west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center (JTWC) releases unofficial advisories. An average of five tropical cyclones form in the North Indian Ocean every season with peaks in May and November. Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD. Throughout the season, the IMD monitored ten depressions, three of which became cyclonic storms. The strongest storm of the year was Super Cyclonic Storm Gay. Crossing the Malay Peninsula into the Bay of Bengal on November 4, Gay became one of the most powerful systems on record in the basin, attaining an estimated pressure of 930 mbar (hPa; 27.46 inHg). Collectively, the storms were responsible for at least 1,785 fatalities, 1,445 of which were due the disastrous flooding triggered by the July Cyclonic Storm, and more than $25 million in damage. ==Storms== ImageSize = width:800 height:200 PlotArea = top:10 bottom:80 right:50 left:20 Legend = columns:4 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/05/1989 till:01/12/1989 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/05/1989 Colors = id:canvas value:gray(0.88) id:GP value:red id:TD value:rgb(0.38,0.73,1) legend:Depression/Deep_Depression id:TS value:rgb(0,0.98,0.96) legend:Cyclonic_Storm id:ST value:rgb(0.80,1,1) legend:Severe_Cyclonic_Storm id:VS value:rgb(1,0.76,0.25) legend:Very_Severe_Cyclonic_Storm id:SU value:rgb(1,0.38,0.38) legend:Super_Cyclonic_Storm Backgroundcolors = canvas:canvas BarData = barset:Hurricane bar:Month PlotData= barset:Hurricane width:10 align:left fontsize:S shift:(4,-4) anchor:till from:23/05/1989 till:27/05/1989 color:ST text:BOB 01 from:07/06/1989 till:13/06/1989 color:TD text:ARB 01 from:12/06/1989 till:14/06/1989 color:TD text:BOB 02 from:20/06/1989 till:21/06/1989 color:TD text:BOB 03 from:22/07/1989 till:25/07/1989 color:TS text:BOB 04 barset:break from:16/08/1989 till:17/08/1989 color:TD text:BOB 05 from:17/10/1989 till:18/10/1989 color:TD text:BOB 06 from:04/11/1989 till:10/11/1989 color:SU text:Gay from:11/11/1989 till:11/11/1989 color:TD text:BOB 08 from:17/11/1989 till:20/11/1989 color:TD text:BOB 09 bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/05/1989 till:31/05/1989 text:May from:01/06/1989 till:01/07/1989 text:June from:01/07/1989 till:01/08/1989 text:July from:01/08/1989 till:01/09/1989 text:August from:01/09/1989 till:01/10/1989 text:September from:01/10/1989 till:01/11/1989 text:October from:01/11/1989 till:01/12/1989 text:November 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「1989 North Indian Ocean cyclone season」の詳細全文を読む スポンサード リンク
