The SummaryTyphoon Forrest (international code 198622) is a 1986 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 56m/s, minimum central pressure 930hPa, not in China Landfall, 1986-10-20 was numbered off, recording 20 track points.
Typhoon Forrest, international code 198622, international name FORREST, 1986 Northwest Pacific typhoon. Formed: 1986-10-15 18:00:00, ended: 1986-10-20 12:00:00. Peak intensity: Super Typhoon, minimum central pressure: 930 hPa, max wind: 56m/s.
Typhoon Forrest at 1986-10-15 18:00:00 at 15.6°N, 153.6°E over the Northwest Pacific; initial intensity: Severe Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 56 m/s (~202 km/h) and a minimum central pressure of 930hPa, recorded at 1986-10-17 06:00:00.
1986-10-20 12:00:00 After, Typhoon Forrest gradually weakened and was numbered off on 1986-10-20 12:00:00 was numbered off; its lifecycle recorded 20 track points.
Typhoon Forrest (198622) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW行—N转—NE移”的抛物线型轨迹. formed初期 (10月15日18时至10月17日12时) , 系统稳定 toward NW, The latitude从15.6°N升至20.1°N, During由153.6°EW移至143.3°E, Moving速度较快且 direction稳定.
During this period, the Typhoon Moving direction gradually shifted from NW to N, with minimal length changes (maintained in the range of 142.2°E to 143.3°E) , indicating that the sub-tropical high-pressure guiding flow weakened, the system Go to turn toward transition period. After the 18th of October at 12 a.m., the path markedly turned toward NE, the latitude continued to N, the length rapidly expanded E. By the 20th of October at 12 a.m., before the dispersal, the Center had reached 36.5°N, 162.5°E, fully Go to the medium-high-latitude wind band control zone. During the entire life cycle, the Typhoon did not landfall any land, always on the ocean.
Forrest's Intensity evolution experienced rapid enhancement, peak maintenance and slow weakening three phases. Initially as Severe Tropical Storm (28m/s) , rapidly strengthened in the toward NWMoving process, upgraded to Super Typhoon in only 30h. On October 17 at 06 at life's peak, max wind recorded 56m/s. Then Intensity slightly declined, but in the near 30h of October 17 at 12 to 18 at 18, the Severe Typhoon level of 46-48m/s, showing strong structural stability.
Compared to 1980 Forrest (top only for Severe Tropical Storm) and 1989 Forrest (top for Severe Typhoon) , its Intensity is significantly stronger; compared to the same name Super Typhoon in 1992 and 1983, although belonging to the Super Typhoon series, but 1986 Forrestined a longer time in Severe Typhoon and above levels, showing typical oceanic deep system characteristics.
