Its peak intensity was severe tropical storm, with maximum winds of 30m/s and a minimum central pressure of 980hPa. It did not make landfall in China, was removed from the numbered system on 1951-05-17, and has 45 recorded track points throughout its lifetime.
Numbering note: Uniform international numbering for the Northwest Pacific has been assigned by the JMA (Japan), the E Tokyo Regional Specialized Meteorological Center, since 1981. This system did not exist in 1951. The 195104 designation is the historical numbering retained by the CMA, and the numbers assigned that year by the JMA (Japan), the Joint Typhoon Warning Center, and China’s meteorological agencies to the same typhoon may differ and cannot be compared directly.
