High resolution directional wave spectrum data were obtained from two NASA airborne radars during the Frontal Air‐Sea Interaction Experiment (FASINEX) in February 1986. The observations show a significant change in the wave number spectrum across the front. On the basis of surveys from a towed sensor and on satellite imagery, the front location and current field are estimated. A numerical model is developed for the wave‐current interaction and is used to model the wave refraction across the frontal current. A parametric study is performed to demonstrate the effects of current meandering. The main consequence of meandering is the formation of caustics and shadow zone regions in which the wave energy is significantly enhanced or reduced. Spectral simulation along the aircraft track reveals a reduction of more than 60% in wave energy in the shadow zone; this is consistent with the observations. |
