Typhoon Sonamu Trail Characteristics
Track and Movement Characteristics
2013年第1号Typhoon “Sonamu”的生命史始 at 2013年1月3日20时, 终 at 1月8日08时, 全程维持Tropical Cyclone 级别, 未发生Landfall. 从空间轨迹来看, 该Typhoon 整体呈现显著的W行Trend, 并伴随轻微的 toward S摆动. formed初期 (1月3日20时至1月4日05时) , 系统位 at lat 9度附近, lng 116-119度海域, 主要 toward WSW. 随后, 路径转 toward 更为纯粹的W toward , 横穿SHainan部海域.
It is worth noting that after reaching the maximum W-end length of 111.9°E on January 5th at 8 p.m., the Typhoon center continued toward W toward 110.0°E on January 6th at 11 p.m., followed by a marked twist toward SWTrend. Between January 6th at 20 p.m. and January 8th at 8 p.m., the latitude continued to decline from 7.4°N to 5.9°N, while the length changes slowed (109.4°E to 108.1°E) , indicating a change in the guiding airflow, resulting in its Moving speed slowing and toward low-latitude waters rotating.
Intensity evolution and historical comparison
在Intensity变化方面, “Sonamu”表现为典型的“快速增强-稳定维持-缓慢减弱”特征. 初始阶段Pressure为1002hPa, max wind 18m/s. 经过约36h的加强, at 1月5日08时达到巅峰状态, 此时中心最低气压降至992hPa, max wind 增至23m/s, intensity 等级确认为Tropical Storm. 巅峰状态维持Time较长, 从1月5日08时至1月6日11时, max wind 稳定在23m/s, 气压在992-994hPa之间小幅波动, 显示出结构相对稳定.
1月6日20时起, 系统开始减弱, 气压回升至998hPa, wind speed降为20m/s. 至生命末期 (1月8日08时) , Pressure升至1004hPa, max wind 降至15m/s, 降级为Tropical Depression. 与同名Typhoon 对比, 2000年第17号Typhoon “Sonamu”peak intensity曾达到Typhoon 级, 而2013年“Sonamu”仅达到Tropical Storm级, 且最低气压992hPa远高 at 2000年同级Typhoon (具体数值虽未给出, 但等级差异明显) , 表明2013年首台Intensity较弱, 属 at 弱Tropical Cyclone 过程.
