Directional Wave Spectrum Phase Velocity Directional Spectrum Laboratory Wind Waves
2009/2/23
A new method for measuring the directional spectrum, introduced in the preceding paper (Rikiishi, 1978), has been applied to actual wind waves in a large experimental tank 70 m × 8 m with the water 3 ...
A New Method for Measuring the Directional Wave Spectrum. Part I. Description
Directional Wave Wave Spectrum
2009/2/23
A new method for measuring the directional wave spectrum is introduced, and the usefulness of the method is examined through numerical analysis of synthetic wave fields. The principle of the method co...
A Study of the Growth of the Wave Spectrum with Fetch
Wave Spectrum fetch consecutive wave buoys
2009/2/10
The development of the wave spectrum with fetch in a steady wind has been studied with a line of consecutive wave buoys in the Bothnian Sea in 1976 and 1979. The relationship that was found between di...
A Near-Inertial Internal Wave Spectrum for the Sargasso Sea in Late Summer
Near-Inertial Internal Wave Spectrum Sargasso Sea Late Summer
2009/1/19
Independent estimates of the frequency–wavenumber spectrum of near-inertial waves for the Sargasso Sea in late summer were made using 8 time series of horizontal velocity from a single moored vertical...

Nonlinear Energy Transfer Gravity-Wave Spectrum Nonlinear Transfer Integral
2009/1/16
A more efficient method of computing the nonlinear transfer in a surface wave spectrum is developed which is symmetrical with respect to all wavenumbers of the resonant interaction quadruplets. This e...
The Effect of the Marginal Ice Zone on the Directional Wave Spectrum of the Ocean
Scott Polar Research Institute Institute of Oceanographic Sciences
2009/1/10
During the MIZEX-84 experiment in the Greenland Sea in June–July 1984, a cooperative program was carried out between the Scott Polar Research Institute (SPRI) and the Institute of Oceanographic Scienc...
Computations of the Response of a Wave Spectrum to a Sudden Change in Wind Direction
Wave Spectrum Wind Direction Sudden Change
2009/1/8
The response of a wind-sea spectrum to a step function change in wind direction is investigated theoretically for a sequence of direction changes ranging from 30° to 180°, in increments of 30°. Two sp...
An Observation of the Directional Wave Spectrum Evolution from Shoreline to Fully Developed
Surface Contour Radar Directional Wave Spectrum Evolution Fully Developed
2008/12/30
The Surface Contour Radar (SCR) is a 36-GHz computer-controlled airborne system, which produces ocean directional wave spectra with much higher angular resolution than pitch-and-roll buoys. SCR observ...
