Typhoon Shirley, international code 197804, international name SHIRLEY, 1978 Northwest Pacific typhoon. Formed: 1978-06-26 00:00:00, ended: 1978-06-30 18:00:00. Peak intensity: Nameless, minimum central pressure: 992 hPa, max wind: 17m/s.
Typhoon Shirley at 1978-06-26 00:00:00 at 11.1°N, 129.5°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Nameless intensity with max winds of 17 m/s (~61 km/h) and a minimum central pressure of 992hPa, recorded at 1978-06-30 00:00:00.
1978-06-30 18:00:00 After, Typhoon Shirley gradually weakened and was numbered off on 1978-06-30 18:00:00 was numbered off; its lifecycle recorded 20 track points.
Typhoon Shirley (197804) 的生命史始 at 1978年6月26日00时, formedPosition位 at lat 11.1°N, 129.5°的Northwest Pacific洋面. 在初始阶段, 该系统呈现稳定的W行Trend. 从6月26日至6月27日中午, 其The latitude基本维持在11.3°N附近, During由129.5°E快速W移至122.8°E, 表明引导气流强劲且 direction单一. 6月27日18时至6月28日12时, 路径出现轻微S折, 纬度降至10.3°N, 随后在S海E部海域经历短暂的停滞与回旋, 经度在117°E至117.4°E之间小幅摆动.
From June 29 00, the system turned toward NW, the latitude gradually N raised, the length continued to W. Until June 30 18 dispersed at lat 14.1°N, 108.1° near, the entire course did not landfall any land. The overall path showed the 'first right W, after SW microfracture, after NW' form, the Moving speed is faster in the pre-period, the intermediate slowdown, the latter period with the toward NW turn toward slightly accelerated.
Thro its lifecycle, Shirley has alwaysined the Nameless level, failing to develop to Tropical Storm or higher Intensity level. Its Max Wind slowly enhanced from the initial 7m/s, to June 27 at 00 to 10m/s, June 27 at 18 at 12m/s andined a longer Time. In the end of life, that is, June 29 at 18 to June 30 at 12, the intensity reached its peak, the max wind was 17m/s, then weakened to 15m/s before dispersing. by the at data, the lowest air pressure loss, can only be judged by wind speed as its Intensity change is more slow, no acute explosion enhancement process.
Looking back at previous records, 1974 Shirley (197418) and 1968 Shirley (196808) both reached the level of Typhoon; while 1965 Shirley (196518) and 1963 Shirley (196303) reached the level of Super Typhoon.
