摘要：

Current measurements collected at a site in the Western North Atlantic are used to study the effectiveness of a finite set of data to represent currents over extended ranges of space and time. The measured currents are found to have large variation from one period to another; power spectra of the data show order-of-magnitude changes within a few months. Using the method of complex demodulation, the amplitudes of inertial period motions are found to vary by a factor of 10 within a few days. It is concluded that finite sets of data should not be used to represent conditions over extended ranges until more is understood about the physical nature of the observed variability. © 1969.
