2015 No. 7 Typhoon “Dolphin” at May 9 in Northwest Pacific low-latitude waters formed, Initial Position at 5.4°N, 161.8°E. Thro its entire life cycle, the Typhoon presented a typical NW toward Moving backward toward NE pylori linear path. During the formed early to May 15th, the system was mainly affected by sub-tropical high-pressure S-side guided airflow, stable toward NW, latitude gradually increased from 5.4°N to 14.2°N, length from 161.8°EW to 144.7°E. May 16 to 17, with the system rising to 15.8°N near, Moving direction began to change subtly, degree W slowed down and gradually turned to life direction. After May 18,
“Dolphin”经历了显著的快速增强过程. 从5月9日的Tropical Storm (18m/s) 起步, 经过约一周的发展, at 5月16日14时跃升为Super Typhoon, wind speed达55m/s, 气压降至930hPa. 随后在5月17日08时至18日02时达到巅峰状态, 中心最低气压低至925hPa, 最大持续wind speed维持在58m/s, 并在此高Intensity等级维持了约42h. 然而, 5月18日20时起, 随着The latitude升高及环境场改变, 其Intensity急剧衰减, 短短12h内wind speed从58m/s骤降至38m/s, 气压回升至965hPa, 此后持续减弱直至消散.
The 22nd Typhoon “Dolphin” peak intensity in 2008 was only Typhoon level (970hPa), while the 12th Typhoon “Dolphin” in 2020 peaked only to Severe Tropical Storm level (980hPa).
