Abstract
In order to investigate the turbulent transport processes in the marine boundary layer, the direct measurement of turbulent fluxes of momentum, sensible heat and water vapor by the eddy correlation method was carried out aboard the R. V. Keifu-Maru over the East China Sea during the AMTEX field programs.
It has been well known that the eddy correlation method is the most reliable means for turbulent flux measurement, but is considered to be difficult of application to shipboard measurement. This difficulty has recently been overcome by the correction technique, which was developed and applied to the pre-AMTEX test cruise by the present author (Mitsuta and Fujitani, 1974).
In the present study some improvement of the correction technique was achieved to make the wind velocity correction more precise. Fluctuations of wind velocity components, air temperature and specific humidity, and motion of the ship were measured aboard the ship and turbulent fluxes were obtained by the eddy correlation method throughout the AMTEX observational periods in 1974 and 1975.
