The SummaryTyphoon Haiyan (international code 200717) is a 2007 Northwest Pacific typhoon; peak intensity Tropical Storm, max wind 18m/s, minimum central pressure 998hPa, not in China Landfall, 2007-10-07 was numbered off, recorded 3 track points.
Typhoon Haiyan, international code 200717, international name HAIYAN, 2007 Northwest Pacific typhoon. Formed: 2007-10-06 14:00:00, ended: 2007-10-07 02:00:00. Peak intensity: Tropical Storm, minimum central pressure: 998 hPa, max wind: 18m/s.
Typhoon Haiyan at 2007-10-06 14:00:00 at 28.5°N, 170°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Tropical Storm intensity with max winds of 18 m/s (~65 km/h) and a minimum central pressure of 998hPa, recorded at 2007-10-06 14:00:00.
2007-10-07 02:00:00 After, Typhoon Haiyan gradually weakened and was numbered off on 2007-10-07 02:00:00 was numbered off; its lifecycle recorded 3 track points.
According to the three consecutive path sampling point data analysis of October 6, 2007 from 14:00 to 07:00, the Typhoon Center began from lat 28.5°N, 170.0°, then toward NE direction and continued to N. Specifically, within the first 6h (14:00 to 20:00) , the latitude rose from 28.5°N to 30.1°N, the length only shifted 0.2°E to 170.2°E; within the subsequent 6h (20:00 to 02:00) , the latitude continued to climb to 31.7°N, while the length remained at 170.2°E unchanged.
这一坐标序列表明, Typhoon “Haiyan”在此期间几乎沿经线 direction直线N上, 横 toward 位移极小, 未出现明显的W折或E偏转 toward 迹象. 其Moving轨迹平滑, 无剧烈摆动, 显示引导气流相对稳定. 由 at track points均位 at 远洋海域 (lng 170°附近) , 且数据明确标注“无Landfall记录”, 确认该Typhoon 全程在开阔洋面上活动, 未对陆地造成直接冲击.
In terms of intensity performance, the 2007 Typhoon “Haiyan” remained constant throughout the observation window.The weather elements of the three Time points were completely consistent: the central minimum air pressure was 998hPa, the max wind was 18m/s, and the intensity level was always at the level of “Tropical Storm”.
In 2013 the 30th Typhoon “Haiyan” had reached Super Typhoon level, minimum pressure low to 890hPa, destructive; in 2001 the 21st Typhoon “Haiyan” also reached Severe Typhoon level, minimum pressure is 954hPa. in comparison, 2007 “Haiyan” only for Tropical Storm, minimum pressure 998hPa high at the first two, max wind 18m/s also much lower at Severe Typhoon and Super Typhoon standard.
| Time | The latitude | During | Intensity | Wind (m/s) | Pressure (hPa) | Moving toward |
