Typhoon Mary Route Analysis
Track and Turning Characteristics
Typhoon Mary (196804) 的生命史长达19天, 整体路径呈现典型的NW行进后转 toward NE的抛物线形态. formed初期, 系统位 at W.Pac平洋低纬度海域 (13°N, 152°E) , 受副热带高压引导, 稳定 toward NW. 在7月19日至7月26日期间, Typhoon 中心纬度从13°N迅速N抬至28.1°N, 经度由152°EW进至136.1°E, 显示出强劲的NW推进动力.
The track’s key turning point occurred near the end of July. After moving beyond 30°N, the system gradually shifted from northwestward to northward movement and then turned toward the northeast. After July 29, the typhoon’s center began moving back toward the east, advancing gradually from 130.8°E to 180°E before dissipating over high latitudes. It made no landfall and remained mainly over the open ocean, causing no direct impacts on land.
Intensity evolution and historical comparison
Mary’s intensity evolution went through three stages: rapid intensification, a peak phase, and gradual weakening. It began as a tropical depression, then intensified into a severe tropical storm within 48 hours. On July 23, it reached super typhoon status near 20.1°N, with central pressure falling to 943 hPa and maximum winds reaching 60 m/s. Its intensity then fluctuated slightly, with pressure dropping further to 940 hPa on July 25 while wind speed eased to 55 m/s, indicating a very compact core and ample energy. After maintaining its peak intensity for about two days, it moved toward higher latitudes and rapidly weakened under the influence of cold sea waters and wind shear, degenerating into a tropical depression by July 29.
Compared with previous storms bearing the same name, Mary in 1968 had a notably stronger intensity. Its minimum central pressure of 924 hPa, based on the peak intensity data provided, was significantly lower than Mary in 1977 at 945 hPa, Mary in 1965 at 940 hPa, and Mary in 1974 at 964 hPa. Although Mary in 1965 also reached super typhoon status, Mary in 1968 had the advantage in terms of minimum pressure, demonstrating greater explosive development. Compared with Mary in 1960 at 970 hPa, Mary in 1968 reached an intensity two categories higher and was a highly representative severe typhoon in the naming sequence.
