Characteristics of Typhoon Nangka
Track and Movement Characteristics
2009年第4号Typhoon “Nangka”的生命周期始 at Philippines以E洋面, 整体呈现稳定的NW toward MovingTrend. 从初始 formed点 (12.1°N, 125.6°E) 至消散点 (23.3°N, 114.4°E) , 系统横跨经度约11度, 纬度N抬约11度. 路径形态较为平直, 未出现明显的回旋或剧烈转 toward . 在6月23日至25日期间, Typhoon 维持WNW, 穿越巴士海峡W侧海域; 随后 at 25日夜间至26日清晨, Moving direction逐渐转为更纯粹的N toward 分量增加, 最终逼近GuangdongE部coastal 但未Landfall. 整个过程中, track points分布均匀, 显示引导气流相对稳定, 无显著的地形阻挡或双Typhoon 互旋效应干扰迹象.
Intensity evolution and structural analysis
该Typhoon Intensity整体偏弱, 巅峰状态仅达到Tropical Storm级别. formed初期Pressure为998hPa, max wind 18m/s. 在 toward WMoving过程中, intensity 经历短暂波动, 25日凌晨曾降级为Tropical Depression (气压995hPa) , 但wind speed维持在20m/s, 显示其内核结构尚存韧性. Go to S海NE部后, 系统 at 26日下午迎来短暂加强期, max wind 增至23m/s, minimum pressure 降至988hPa, 达到生命周期峰值. 然而, 这一高Intensity状态维持Time极短, 仅持续约6h. 26日夜间起, 随着纬度升高及靠近land, 系统迅速减弱, wind speed回落至18m/s并最终在27日早晨降级为Tropical Depression后消散. 全程无Landfall记录, 表明其近岸衰减速度快 at 预期.
Comparison of Typhoon
将2009年“Nangka”与历届同名Typhoon 进行对比, 其Intensity显著偏弱. 2015年第11号Typhoon “Nangka”曾发展为巅峰气压915hPa的Super Typhoon, 破坏力极强; 2020年第16号Typhoon “Nangka”虽同为988hPa的最低气压, 但等级达到Severe Tropical Storm, 整体能量高 at 2009年版本. 相比之下, 2003年第5号Typhoon “Nangka” (最低气压991hPa, Tropical Storm) 与2009年个案最为接近, 两者均属 at 生命史较短, Intensity有限的Tropical Cyclone . 2009年“Nangka”作为典型的弱Tropical Storm, 其气象特征更倾 toward at 受环境风切变或干空气侵入抑制的快速生消过程, 不具备长期维持高Intensity的条件.
