Typhoon Grace Route Analysis
Track and Movement Characteristics
Typhoon Grace (196409) 的生命史始 at Northwest Pacific洋面, 整体路径呈现复杂的“W进-停滞回旋-N上”形态. formed初期 (7月26日至28日) , 系统自E toward W快速Moving, 纬度维持在20°N至22°N之间, 经度从138.2°E迅速W移至130.6°E, 显示出稳定的W引导气流. 7月29日至8月1日期间, Typhoon Go to 显著的停滞与回旋阶段. 在此期间, Center在128.8°E至131.9°E, 19.5°N至22.2°N的狭小区域内震荡, Moving速度极缓, 甚至出现短暂的 toward E回流现象, 表明当时周围大尺度环境流场较弱或存在多系统相互作用.
From August 2, the latitude climbed rapidly from 22.9°N to 30.2°N, the length then slowly twisted W to 129.5°E, eventually dispersing at higher latitudes.
Intensity evolution and historical comparison
在Intensity变化方面, Grace经历了典型的“快速增强-迅速减弱-末期再发展”过程. 7月26日初生时为Tropical Depression (12m/s) , 随后在 toward WMoving过程中快速加强, at 7月28日00:00达到peak intensity, 定为Severe Tropical Storm, max wind 25m/s. 然而, 巅峰状态维持Time极短, 仅12h后便开始减弱, 至7月29日中午已降级为Tropical Depression, 并在随后的回旋期内长期维持10m/s左右的微弱Intensity. 值得注意的是, 在生命末期 (8月3日00:00) , 随着系统 toward NMoving, intensity 曾短暂回升至Tropical Storm级别 (23m/s) , 随后再次减弱并结束观测.
Compared to History, the 1964 Grace peak intensity (Severe Tropical Storm, 25m/s) was equal to the 1975 Grace (197516) and the 1972 Grace (197213) and both reached Severe Tropical Storm level, but strong at 1961 Grace (196112) Tropical Storm level.
