Typhoon Orchid Trail Characteristics
Track and Movement Characteristics
The lifecycle of Typhoon Orchid (198318) began over the Northwest Pacific at 20:00 on November 16, 1983, with its initial position at 10°N, 139°E. During its early formation stage, the system followed a pronounced westward trend, moving rapidly from 139°E to near 128°E while its latitude rose slowly from 10°N to 13°N. From November 19 to 20, the track made a marked turn, with longitude changes slowing as the system nearly stagnated between 127°E and 128°E and rotated slightly, before shifting to a steady north-northwestward track.
After entering the mature phase, Typhoon Orchid’s center moved northward over the eastern Philippine Sea, with its longitude fluctuating slightly between 125°E and 126°E and its latitude increasing from 13.5°N to 17.6°N. Notably, during its peak-maintenance phase from November 22 to 24, the track displayed the characteristic northward kink, with longitude remaining nearly stable while latitude increased rapidly. Near the end of its life, the system moved to waters north of 18°N near 124°E, slowed further, and finally weakened into a Tropical Depression at 08:00 on November 26. Throughout its entire lifecycle, the typhoon made no landfall and remained over the open ocean.
Intensity evolution and historical comparison
Orchid的Intensity演变经历了完整的“ formed-增强-巅峰-减弱”过程. 初始阶段气压为1006hPa, wind speed10m/s. 经过约4天的快速增强, at 11月20日发展为Typhoon 级别. 随后Intensity波动上升, 在11月22日首次达到Severe Typhoon标准 (50m/s, 940hPa) . 尽管11月22日晚曾短暂减弱, 但系统迅速重新组织, at 11月24日08时达到生涯巅峰, 录得最低气压930hPa及Max Wind55m/s, 确认为Super Typhoon等级. 巅峰状态维持Time较短, 随后受环境因素影响, 气压迅速回升至950hPa以上, wind speed骤降至35m/s以下, 并在最后48h内快速衰减为Tropical Depression.
Compared with previous storms bearing the same name, the 1983 Orchid’s peak intensity was highly representative. Its minimum central pressure of 930hPa matched the 1994 Orchid (199427) and 1991 Orchid (199121), all reaching exceptionally high intensity standards. By contrast, the 1987 Orchid (minimum central pressure of 955hPa) and 1980 Orchid (minimum central pressure of 960hPa) had markedly weaker peak intensities. This indicates that the 1983 system belonged to the first tier of Severe Typhoon cases in the naming sequence for Orchid, demonstrating the explosive potential that Northwest Pacific typhoons may attain in late autumn.
