Subseasonal coastal-trapped wave propagations in the Southeastern Pacific and Atlantic Oceans : 1. A New approach to estimate wave amplitude

The Humboldt and the Benguela upwelling systems are connected to the equatorial variability through the coastal waveguide, so that a large variance of the coastal sea level and current variability can be described as an infinite sum of orthonormal free Coastal-Trapped Wave (CTW) modes. The objective of this study is to infer the CTW mode contributions to the coastal variability in both systems at subseasonal timescales (
