2021年第17号Typhoon “Lionrock”的生命史始 at S海中部海域, 整体路径呈现显著的“先N后W”折 toward 特征. formed初期 (10月6日至7日) , 系统中心位 at lat 15.2°至15.8°N, 111.4°至112.4°之间, 主要维持N direction缓慢Moving, 期间During变化较小, 显示其受引导气流影响较弱或处 at 鞍形场中. 10月8日凌晨至上午, Typhoon 中心 at 17.3°至17.6°附近出现明显的路径转 toward , 由N转为WNW. 这一转 toward 点标志着系统开始加速靠近Hainan岛E部coastal . Landfall后 (10月9日至10日) , Typhoon 中心穿越Hainan岛Go to N部湾, 路径持续 toward W延伸, 最终 at 10月10日17时 weakened into Nameless并移出监测范围. 整个过程中, 76 track points记录了其从S海中部到N部湾W部的完整轨迹, Moving速度在Landfall前后保持相对稳定, 未出现剧烈的停滞或打转现象.
在Intensity变化方面, “Lionrock”表现为典型的“近海增强, Landfall维持”特征. 初始阶段为Nameless (12m/s, 1002hPa) , 随着 toward NMoving, at 10月7日晚加强至15m/s. 10月8日上午正式升级为Tropical Storm, 并在接近Hainan琼海时达到peak intensity, max wind 20m/s, minimum pressure 降至990hPa. 值得注意的是, 该Typhoon 在10月8日22:50LandfallHainan琼海后, intensity 并未迅速衰减, 而是在随后两天内 (10月9日至10日上午) 长Time维持在Tropical Storm级别 (20m/s, 990hPa) , 显示出较强的生命力及水汽输送能力. 直至10月10日下午Go to Guangxicoastal 附近, wind speed才逐渐降至18m/s, 并 at 傍晚进一步 weakened into Nameless.
In 2016, the 10th Typhoon “Lionrock” had developed into the top air pressure 935hPa Super Typhoon, in 2010, the 6th Typhoon “Lionrock” also reached the Severe Tropical Storm level (minimum air pressure 980hPa) .
