MEASUREMENT OF TURBULENT FLUXES FROM A MOVING SHIP (3)

By 寧 光田, 徳之助 藤谷 and 泰一 林

Abstract

A new method for the direct measurement of turbulent fluxes over the ocean from amoving ship developed by the authors was applied to the studies of air mass modificationsover the Kuroshio current during the AMTEX field observation period of February, 1974.The vertical component of wind velocity was corrected also for vertical motion of a shipbody, which had been neglected in the previous study. During the observing period, pronoun-ced clockwise rotations of wind direction in a few days period was observed. All the meteoro-logical parameters including the turbulent fluxes changed with the same period. Theaveraged transfer coefficients of momentum, sensible heat and latent heat corrected for thebight of lOin are 1.32x10-3 1.40x10-3 and 1.40x10-3 respectively.A new method for the direct measurement of turbulent fluxes over the ocean from amoving ship developed by the authors was applied to the studies of air mass modificationsover the Kuroshio current during the AMTEX field observation period of February, 1974.The vertical component of wind velocity was corrected also for vertical motion of a shipbody, which had been neglected in the previous study.
