Typhoon Bilis trajectory analysis
Track and Movement Characteristics
Typhoon Bilis (200604) 的生命周期始 at 2006年7月9日14时, formed at Northwest Pacific洋面 (13.5°N, 136.8°E) , 终 at 7月15日16时在江W境内 weakened into Tropical Depression (26.1°N, 114.4°E) . 从路径采样数据来看, 该Typhoon 整体呈现稳定的NW toward MovingTrend. 在初始阶段 (7月9日至11日) , 系统自E toward W跨越Philippines以E洋面, 纬度由13.5°NN抬至17.7°N, 经度由136.8°EW进至129.7°E, Moving速度较快且 direction稳定.
Go to key turning period (July 12-13) , Typhoon center continued toward NW direction advancing, gradually approaching SEcoastal . It is noteworthy that although track points showed its continuous approach toland, the data clearly marked 'no Landfall record', which indicates that Typhoon center did not directly cross the coastline Go to inland, but rather the near sea sprinkled or coastal coastal coastline parallel Moving way affected the area. After July 14, the route turned toward W direction deep inland, the latitude continued to rise to 26.9°N nearby after slightly began to have S falls, eventually dispersed in Lake S, Jiang W boundary area. The entire route span is large, covering the latitude range, broadly embodying the characteristic of typical summer Typhoon
Intensity evolution and historical comparison
在Intensity变化方面, Bilis经历了典型的“增强-维持-减弱”过程. formed初期为Tropical Storm (18m/s, 996hPa) , 随后迅速加强. 7月12日20时, Pressure降至980hPa, wind speed达到30m/s, 升级为Severe Tropical Storm. 此后直至7月14日12时, Typhoon 维持在Severe Tropical Storm级别, minimum pressure 触及975hPa, max wind 稳定在30m/s, 显示出其在近海期间结构相对稳定, 能量维持Time较长. 然而, 一旦深入内陆 (7月14日19时后) , 受地面摩擦及水汽切断影响, intensity 急剧衰减, wind speed在不到一天内由30m/s降至16m/s, 气压回升至989hPa, 最终转化为Tropical Depression.
Compared with the same name History, the 2000 Billis (200010) peak intensity had reached Super Typhoon level, minimum pressure lower than 920hPa. In comparison, 2006 Billis was only Severe Tropical Storm, minimum pressure 975hPa, both of which have significant quantitative differences on peak intensity.
