• Estimation of a 2D Surface Current Field Using Radial Current Velocities Measured by HF Ocean Radar

抄録

A method for estimating a 2D surface current field has been developed by using radial current velocities measured by HF ocean radar. The method includes the second order partial differential equations in terms of a potential function and a stream function, which can describe a general 2D flow and are related with the current velocity components in the beam and azimuthal directions and their derivatives. The 2D current fields were estimated under the appropriate boundary conditions including the true or measured azimuthal current velocities and were compared with the target current fields. The estimated results generally show good agreements with the target current fields, whereas they show the non-negligible differences between them for the cases that the current velocities are large and vary rapidly in space.
