Typhoon June trajectory
Track and Movement Characteristics
Typhoon June (198717) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现显著的NW toward 转NE toward 的抛物线形态. formed初期 (9月27日) , 系统位 at 14.6°N, 160.3°E附近, 受副热带高压S侧E气流引导, 稳定 toward NW. 在9月27日至28日期间, 其纬度从14.6°N迅速N抬至22.2°N, 经度由160.3°EW移至157.4°E, 显示出较强的 toward N分量.
The critical turn toward process occurs between September 29 and 30. As the system N enters the mid-high latitude region of 25°N to N, influenced by the SW airflow before the W wind belt, Moving direction gradually turns from NW to positive N, and then turns toward NE. During September 30 00:00 to 12:00, the length from 149.7°E slightly retreated to 148.6°E after the rapid E shift, marking the turn toward completion.
Intensity evolution and historical comparison
在Intensity变化方面, June表现为“快速增强, 短暂巅峰, 缓慢减弱”的特征. 初始阶段为Tropical Depression, wind speed7m/s. 经过约36h的持续加强, at 9月29日06:00达到生命史巅峰, intensity 定为Tropical Storm, max wind 20m/s. 值得注意的是, 其peak intensity维持Time极短, 仅6h后 (9月29日12:00) 即减弱回Tropical Depression (17m/s) , 随后Go to 漫长的减弱期. 在剩余的近三天Time内, wind speed从17m/s逐步递减至10m/s, 直至消亡. 气压数据缺失, 但wind speed变化清晰反映了其结构受垂直风切变或冷海水影响的衰减过程.
Historical data show that the 1961s, 1969s and 1981s of the same name Typhoon reached the level of Typhoon or above (Severe Typhoon, Super Typhoon), June 1984 also reached the level of Severe Tropical Storm.
