The SummaryTyphoon Yunya (international code 199105) is a 1991 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 53m/s, minimum central pressure 950hPa, not in China Landfall, 1991-06-17 was numbered off, recording 22 track points.
Typhoon Yunya, international code 199105, international name YUNYA, 1991 Northwest Pacific typhoon. Formed: 1991-06-11 18:00:00, ended: 1991-06-17 00:00:00. Peak intensity: Super Typhoon, minimum central pressure: 950 hPa, max wind: 53m/s.
Typhoon Yunya at 1991-06-11 18:00:00 at 11°N, 127.2°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 53 m/s (~191 km/h) and a minimum central pressure of 950hPa, recorded at 1991-06-14 06:00:00.
Typhoon Yunya gradually weakened and was numbered off on 1991-06-17 00:00:00 was numbered off; its lifecycle recorded 22 track points.
Typhoon Yunya (199105) 的生命周期始 at Northwest Pacific洋面, 整体路径呈现稳定的NW toward MovingTrend, 未出现明显的转 toward 或回旋现象. 从 formed初期的11°N, 127.2°E至消散末期的22.6°N, 121.5°E, 系统始终维持WNW的行进 direction. 在Moving速度方面, 初期 (6月11日至13日) The latitude变化较缓, During toward W推进明显; Go to 中期 (6月14日至15日) , 随着Intensity达到巅峰, 其 toward N分量逐渐增加, 纬度从14.5°N迅速跃升至17.7°N, 显示出引导气流的变化. 值得注意的是, 该Typhoon 全程无Landfall记录, 主要在开阔洋面上活动, 最终在Taiwan以E海域减弱消散. track points分布均匀, total 计22个采样点, 完整记录了其从Nameless发展至Super Typhoon再衰减的全过程.
Yunya's Intensity evolution has a typical 'fast enhancement - short peak - rapid weakening' characteristic. The system was upgraded to Tropical Storm at 18 a.m. on June 12, then crossed the Severe Tropical Storm, Typhoon and Severe Typhoon levels in approximately 36 hours. On June 14, at 06 a.m., it reached its peak at 14.5°N, 123.6°E, the center of Max Wind recorded 53m/s, ranked Super Typhoon. However, the peak stateined Time extremely short, after only 6hwind speed dropped to 48m/s, declined to Severe Typhoon. Then, the system Go to rapid weakening period, from June 14, at 12 a.m. to June 15, 18, the max wind 48m/s dropped to 17m/
Based on the existing data, the 5th Typhoon Yunya of 1991 showed extremely strong explosive power, peak wind speed up to 53m/s, belonging at Super Typhoon level. Compared to at other tropical cycles of the same name or code similar in history, the process is characterized by the fact that the Landfall does not cause direct land disasters, but its intensity reached in the far ocean is extremely high, and the weakening process is extremely rapid. The missing specific minimum pressure value in the data can not directly compare with the air pressure indicator, but only from the wind speed dimension consideration, the value of 53m/s is sufficient to make it a significant position in the 1991 Northwest Pacific Typhoon season, reflecting the high potential development of the summer heat cycle in the ocean.
