Typhoon Roke Trail Characteristics
Route Moving and Landfall Features
2017年第7号Typhoon “Roke”的生命史相对短暂, 其观测数据覆盖时段为2017年7月22日08:00至7月23日14:00. 从空间轨迹来看, 该Typhoon formed at Philippines以E洋面 (20.9°N, 120.5°E) , 整体呈现稳定的WNWTrend. 在7月22日08:00至22:00期间, Typhoon 中心纬度从20.9°N缓慢N抬至21.6°N, 经度则由120.5°E快速W移至117.2°E, 显示出较强的 toward W分量. Go to 7月23日凌晨后, Moving路径略微 toward N调整, 但总体仍保持 toward NW direction逼近华Scoastal 的态势.
According to the Landfall record, Typhoon Center at 09:50 on July 23, 2017 in Hong KongNE coastal Landfall. Landfall prior (08:00) center position at 22.3°N, 114.8°E, Landfall after continuing toward NW deep inland, to 14:00 has been Moving to 22.7°N, 113.3°E. No apparent twist or sharp twist toward phenomenon occurred during the entire path, the path is more flat, beneficial at Forecast tracking.
Intensity evolution and historical comparison
在Intensity变化方面, “Roke”表现为典型的近海加强, Landfall即减弱特征. 初始阶段为Tropical Depression (15m/s, 1000hPa) , at 7月22日18:00增强为Tropical Storm (18m/s, 998hPa) . 此后直至Landfall前, 其Max Wind维持在18m/s, Pressure稳定在998hPa. 在临近Landfall的7月23日10:00, intensity 达到巅峰, max wind 增至20m/s, minimum pressure 降至995hPa. Landfall后, 受land摩擦及水汽切断影响, intensity 迅速衰减, 12:00wind speed回落至18m/s, 14:00进一步 weakened into Tropical Depression (16m/s, 1000hPa) .
Data show that in 2011 'Roke' peak intensity is Typhoon level (minimum atmospheric pressure 950hPa), in 2022 'Roke' has reached Severe Typhoon level (minimum atmospheric pressure 955hPa), even the weaker 2005 'Roke' has reached Severe Tropical Storm level (minimum atmospheric pressure 980hPa) .
