2000-09-18 06:00:00 After, Typhoon Sonamu gradually weakened and was numbered off on 2000-09-18 06:00:00 was numbered off; its lifecycle recorded 18 track points.

Typhoon Sonamu Trail Characteristics

Track Track and Moving Features

Typhoon Sonamu (200017)'s life began at the Northwest Pacific ocean surface, and the overall path showed significant toward NE characteristics, without direct landfall effects on land.From the initial formed Position (21.5°N, 138.3°E) to the dispersal stage, its length variation was relatively small, mainly concentrated between 138°E and 149°E, while the latitude range was enormous, from low latitude 21.5°N rapidly up to high latitude 44.5°N, with the total latitude range exceeding 23 latitudes.

In terms of Moving speed, the previous period (September 14 to 15) Moving is relatively slow, 6h through the latitude variation is limited; Go to September 16th, as the latitude rises, the Moving speed is significantly accelerated, especially in the period of September 17 to 18, each 6h latitude increase reaches 2° to 3° above, showing significant characteristics influenced by the W wind belt guided air flow.

Intensity Evolution and Historical Comparison

该Typhoon 经历了完整的“Nameless-Tropical Storm-Severe Tropical Storm-Typhoon ”增强过程. 9月14日00时为Nameless (10m/s) , 随后稳步加强, at 9月15日00时升级为Tropical Storm, 9月15日18时达到Severe Tropical Storm级别 (30m/s) , 并在9月16日00时正式发展为Typhoon (33m/s) . 值得注意的是, 其在达到Typhoon Intensity后, max wind 并未立即达到峰值, 而是维持在一个相对稳定的高Intensity平台期. 从9月16日00时至9月18日00时, max wind 保持在33m/s至38m/s之间, 其中peak intensity出现在9月17日06时至18时期间, max wind 达38m/s. 即使在9月18日06时移至44.5°N的高The latitude地区, 其Intensity仍维持在Typhoon 级别 (33m/s) , 显示出较强的生命力.

与同名Typhoon 对比, 2000年的SonamuIntensity远超2013年的第1号Typhoon Sonamu. 2013年Sonamu巅峰仅为Tropical Storm级别, minimum pressure 992hPa; 而2000年Sonamu不仅达到了Typhoon intensity with max winds of 更是高达38m/s, 两者在Intensity等级上存在本质差异, 表明2000年Sonamu是一个发展更为充分, 能量更强的热带气旋系统.
