Abstract

Using the mobile weather station wind data installed on the "Prince" cruise ship on Qinhuangdao from August 2 to 10, 2016, the wind speed(sea wind) on the cruise ship route was obtained using the true wind observation algorithm. A comparative analysis of the meteorological observation station(near-shore wind) in the Haigang District closest to this cruise ship terminal and the Qinhuangdao National Basic Weather Station(land wind) shows that when controlled by the weak pressure field, the sea wind speed of Qinhuangdao is generally greater than the near-shore wind speed and the land wind speed about 1 to 2 wind levels. The use of near-shore wind speed to revise the sea wind speed is slightly better than the use of land wind speed to revise the sea wind speed; The sea winds are generally deflected clockwise from the near-shore winds and the land winds.However, it is unrealistic to use the near-shore wind or land wind direction to accurately adjust the sea wind direction.
