Typhoon Thelma, international code 198322, international name THELMA, 1983 Northwest Pacific typhoon. Formed: 1983-12-14 12:00:00, ended: 1983-12-18 06:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 990 hPa, max wind: 28m/s.
Typhoon Thelma at 1983-12-14 12:00:00 at 8.6°N, 142.8°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 28 m/s (~101 km/h) and a minimum central pressure of 990hPa, recorded at 1983-12-17 00:00:00.
1983-12-18 06:00:00 After, Typhoon Thelma gradually weakened and was numbered off on 1983-12-18 06:00:00 was numbered off; its lifecycle recorded 16 track points.
Typhoon Thelma (198322) 的生命周期始 at Northwest Pacific远洋海域, 整体路径呈现显著的“先W后N再折 toward E”的复杂形态. formed初期 (12月14日至15日) , 系统位 at lat 8.6°至11.8°N, 142.8°至135.9°之间, 受低纬引导气流影响, 保持稳定的WNW, 日均移速较快, 横跨约7个During.
At the arrival of lat 13.5°N, near 133.6°, the Moving direction shifted from NW to near-real N, then at 14.7°N, at 133.3°C to the most N-end latitude before the short stagnation.
该Typhoon Intensity演变具有“快速增强, 巅峰短暂, 迅速衰减”的特征. 初始阶段为Nameless, wind speed10m/s. 经过约36h的持续加强, at 12月16日00:00升级为Tropical Storm (20m/s) , 并在12月16日18:00达到Severe Tropical Storm级别. 12月17日00:00, 系统达到peak intensity, max wind 录得28m/s. 然而, 巅峰状态维持Time极短, 仅6h后 (12月17日06:00) wind speed即回落至23m/s, 降级为Tropical Storm, 随后加速 weakened into Nameless, 直至消散.
Its peak intensity is Severe Tropical Storm (28m/s) , weak at 1987 Thelma (Super Typhoon) and 1977 Thelma (Severe Typhoon) , with the 1980 Thelma (Severe Tropical Storm) level comparable, but slightly strong at 1991 Thelma (Tropical Storm) . Given at its formed at mid-December winter wind Active period, and not landfall land, the Typhoon mainly reflects the winter tropical cycle under the influence of vertical wind cuts or dry air invasion, difficult to maintain the structural characteristics of high Intensity.
