Analysis of Typhoon Shirley's Track Characteristics

Track and Movement Characteristics

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, 其纬度基本维持在11.3°N附近, 经度由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 presented 'first right W, after SW microfracture, after NW' form, Moving speed faster in the pre-period, medium slowdown, later with toward NW turn toward slightly accelerated.

Intensity evolution and historical comparison

Thro its lifecycle, Shirley has alwaysined the Tropical Depression level, failing to develop to the 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 peaked, the max wind was 17m/s, then weakened to 15m/s before dispersal. by the at data, the lowest air pressure deficiency, can only be judged by the wind speed to change its Intensity more slowly, without a dramatic 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.
