Analysis of Typhoon Tess
Path and Moving Characteristics
Typhoon Tess (197508) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW—N—NE”抛物线型Moving轨迹. formed初期 (9月1日至3日) , 系统自151.4°E附近 toward NW direction缓慢Moving, 纬度从17.2°N升至19.3°N, 经度W移约2度, 显示其受副热带高压S侧引导气流影响显著. 9月4日至5日为路径的关键转折期, Typhoon 在达到最强Intensity后, Moving direction逐渐由NW转为正N, 随后偏 toward NE. 特别是在9月6日至7日期间, 纬度迅速从25°N推进至28.5°N, 而经度变化较小, 表明此时系统开始受到W风带槽前气流牵引, 发生明显的转 toward . 9月8日之后, Typhoon 加速 toward NE, 最终 at 9月10日20时到达46.8°N的高纬度海域并消散. 全生命周期内无Landfall记录, 主要活动范围集中在开阔洋面.
Intensity evolution and historical comparison
Typhoon Tess underwent a complete formation–intensification–peak–weakening life cycle. At formation on September 1, it was a tropical depression with winds of 10 m/s and a central pressure of 1000 hPa. It then intensified rapidly, reaching peak intensity just three days later at 20:00 on September 4, with a minimum central pressure of 945 hPa and maximum winds of 50 m/s, making it a severe typhoon. After maintaining peak intensity for about one day, its intensity began to fluctuate and decline as it moved to higher latitudes and the environmental field changed. After September 6, its pressure rose above 955 hPa and its wind speed fell below 40 m/s, reducing it to a common typhoon. At higher latitudes, although its pressure briefly fell anomalously to 965 hPa near the end of September 10, its wind speed remained at 25 m/s and its structure had begun to take on characteristics of a temperate cyclone.
Compared with previous typhoons of the same name, Tess in 1975 was significantly stronger. Its peak central pressure of 945 hPa was far lower than those of Tess in 1988 (975 hPa), 1985 (965 hPa), 1978 (968 hPa), and 1982 (988 hPa). Tess in 1982 reached only tropical storm intensity, whereas Tess in 1975 not only reached severe typhoon status but also had a substantially lower central pressure. This indicates that the 1975 storm had accumulated more energy and had greater explosive potential that year, making it a highly representative intense case in the series of storms sharing the same name.

FAQ
Typhoon Tess was the 1975 Typhoon.
The identifier 197508 for Typhoon Tess is the historical number retained by the CMA, representing the eighth typhoon of 1975, while its international name was TESS. International standardized numbering for the Northwest Pacific began in 1981; before then, individual agencies used their own numbering systems. The numbers assigned by JMA (Japan), the Joint Typhoon Warning Center in the United States, and China’s meteorological authorities to the same typhoon might differ and therefore cannot be compared directly.
Where does Typhoon Tess's track data come from?
Path. Data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speed refers to 2-min sustained wind speed. Track points at intermediate times are encrypted based on original operational positioning data, while wind speed and pressure are interpolated using best-track anchor points.
What is the highest level of Typhoon Tess?
Typhoon Tess peak intensity is Severe Typhoon, max wind 50m/s, minimum central pressure 945 hPa.
Is there a typhoon TessLandfall?
According to records, Typhoon Tess is not in our coastal landfall.
Where can I view typhoon Tess's live track map?
