Analysis of Typhoon Bess
Path and Moving Characteristics
Typhoon Bess (197123) 的生命史长达10天, 整体路径呈现典型的NW行后转 toward NE的抛物线形态. formed初期, 系统位 at W.Pac平洋远洋海域 (16.5°N, 150.8°E) , 随后稳定 toward NW. 在9月17日至9月21日期间, Typhoon 中心纬度从16.5°N缓慢N抬至21.9°N, 经度则从150.8°E大幅W进至130.9°E, 显示出强劲的 toward W推进动力.
The track's key turning point occurred after September 21. As it continued moving north, its direction gradually shifted from northwest to due north and then toward northeast. At 02:00 on September 24, the typhoon center reached 29.5°N, 117.9°E, where its longitude began adjusting eastward, marking the completion of the turn. The system then accelerated toward the northeast and weakened near 41.5°N, 136.2°E on September 27. It made no landfall during its lifetime and was mainly active over the open ocean and high-latitude seas.
Intensity evolution and historical comparison
Bess underwent three stages of intensity evolution: rapid intensification, a prolonged peak, and rapid weakening. It began as a tropical depression and intensified into a severe typhoon in about 36 hours. At 14:00 on September 19, its intensity surged to super typhoon status, with winds of 60m/s and a central pressure of 918hPa. It reached its lifetime peak at 02:00 on September 21, with maximum winds of 65m/s and a minimum pressure of 905hPa. The peak lasted about two days before environmental factors caused its intensity to fluctuate and decline. After September 22, the system weakened rapidly as it moved poleward. By September 24, it had downgraded to a tropical storm and eventually became an extratropical cyclone or dissipated over the cold, high-latitude ocean.
Compared with previous typhoons bearing the same name, Bess in 1971 had a remarkably high intensity. Its minimum pressure of 905hPa ranked second only to Bess in 1982 at 901hPa and was far lower than the values recorded by Bess in 1996 at 975hPa, 1979 at 955hPa, and 1978 at 983hPa. Both the 1971 and 1982 storms reached super typhoon intensity, while the other storms reached only typhoon or severe tropical storm intensity. This indicates that the name Bess tends to produce intense tropical cyclones under certain meteorological conditions.

International numbering for the Northwest Pacific did not begin until 1981. Before then, meteorological agencies maintained separate numbering systems, so the numbers assigned by JMA (Japan), the Joint Typhoon Warning Center in the United States, and Chinese meteorological authorities for the same typhoon may differ and cannot be directly compared.
Where does the track data for Typhoon Bess come from?
