Typhoon Opal, international code 199705, international name OPAL, 1997 Northwest Pacific typhoon. Formed: 1997-06-13 12:00:00, ended: 1997-06-21 06:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 960 hPa, max wind: 46m/s.
Typhoon Opal at 1997-06-13 12:00:00 at 12.1°N, 138.8°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Typhoon intensity with max winds of 46 m/s (~166 km/h) and a minimum central pressure of 960hPa, recorded at 1997-06-17 12:00:00.
Typhoon Opal gradually weakened and was numbered off on 1997-06-21 06:00:00 was numbered off; its lifecycle recorded 32 track points.
Typhoon Opal (199705) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“先NW后NE”的抛物线型轨迹. formed初期 (6月13日至15日) , 系统位 at 12°N-14°N, 133°E-138°E之间, 主要 toward NW direction缓慢Moving, The latitude逐渐N抬, During持续W进. 6月16日至17日期间, Moving direction发生微妙变化, 经度W进速度显著减缓, 甚至在132.4°E至132.8°E区间出现近乎停滞或微幅E退的迹象, 随后转为稳定的N路径.
June 18-19 is a key period of path turning, while the systemins the length near 133.6°E, while the latitude rapidly jumps from 20.9°N to 27.4°N, showing an extremely strong toward N propulsion momentum. June 19 after 12 a.m., as the latitude breaks through 30°N, the system begins to significantly turn toward NE, the length from 134.2°E rapidly toward E expands to 148°E. Thro the process, the Typhoon failed to landfall any land, remained in marine activity, and eventually disintegrated at the high latitude on June 21.
The initial phase was Nameless, wind speedined at 7m/s to 12m/s. June 16 intensified into Tropical Storm, then rapidly upgraded to Typhoon within 24h, and at June 17 at 12 am reached Severe Typhoon intensity with max winds of recorded 46m/s. It is worth noting that from June 17 at 12 to June 19 at 00, the systemined 46m/speak intensity within 36h, and the Centerined almost unchanged in duration, showing its smaller vertical wind cuts, with extremely high structural stability in a suitable environment.
After 12 a.m. on June 19, with the system N on Go to High-latitude cold sea zone, the intensity began to decline gradually, from Severe Typhoon to Typhoon, then weakened into Severe Tropical Storm and Tropical Storm. In contrast to previously identified Typhoon, the 1997 Opal's peak intensity (Severe Typhoon, 46m/s) was significantly high at 1976 (Nameless), 1973 (Typhoon) and 1970 (Severe Tropical Storm) systems of the same name, but slightly lower at 1967 Super Typhoon level.
