Typhoon Ben, international code 197923, international name BEN, 1979 Northwest Pacific typhoon. Formed: 1979-12-17 00:00:00, ended: 1979-12-23 12:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 994 hPa, max wind: 30m/s.
Typhoon Ben at 1979-12-17 00:00:00 at 7°N, 149°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 30 m/s (~108 km/h) and a minimum central pressure of 994hPa, recorded at 1979-12-22 18:00:00.
1979-12-23 12:00:00 After, Typhoon Ben gradually weakened and was numbered off on 1979-12-23 12:00:00 was numbered off; its lifecycle recorded 27 track points.
Typhoon Ben (197923) formed at Northwest Pacific低The latitude海域, 其生命史呈现出显著的W行后转 toward N上的“L”型路径特征. 初始阶段 (12月17日至19日) , 系统位 at 7°N至9°N之间, 受低层引导气流影响, 保持稳定的W, During从149°E快速W移至137°E, 日均移速较快. 12月20日起, 随着纬度缓慢N抬至10.9°N, Moving direction逐渐由正W转为NWW.
When the system Moving to 124°E near, the path curvature changes significantly, from NW toward gradually to N direction. On the morning of December 23, Centerined at 119.5°E near, then rapidly toward N accelerated Moving, until the day 12 had reached 19.6°N, 123.4°E. Thro the lifecycle, the Typhoon did not landfall any land, was always active at sea, and eventually decayed in higher latitudes.
在Intensity演变方面, Ben经历了从Nameless到Severe Tropical Storm的完整发展过程. formed初期 (12月17-19日) , 系统维持Nameless等级, max wind 稳定在7m/s. 12月20日, 随着对流发展, wind speed提升至10-12m/s. 12月21日00时, 系统增强为Tropical Storm, wind speed达到20m/s, 并在此Intensity维持约一天. 12月22日中午, Typhoon 达到peak intensity, 升级为Severe Tropical Storm, max wind 增至28m/s, 接近30m/s的极值标准. 然而, 巅峰状态持续Time较短, 12月23日中午, 系统在N上过程中迅速 weakened into Nameless, wind speed骤降至12m/s, 显示其在高The latitude或垂直风切变增大环境下结构快速崩溃.
Compared with the same name Typhoon, Ben's Intensity in 1979 was significantly weak at 1986 Ben (198618, peaked as Super Typhoon), but with the peak level of 1983 Ben (198306, peaked as Severe Tropical Storm) was comparable.
