Sea level, tide, tidal prediction, tidal constants, statistical analysisAbstract
The sea level behavior was studied at Cartagena, Coveñas and Santa Marta areas, three important cities of Colombia's continental region in the Caribbean. The tide (due to astronomical forces) and the non tidal residual were analyzed by separate. Tidal series were predicted by harmonic analysis, using in situ sea level series or generated by a long wave numerical model with tide information from a worldwide database as boundary conditions. The non tidal residual was obtained subtracting the tide from in situ sea level series. Series of non tidal residual were generated using statistical simulations, which were added to the tide series to obtain the expected sea level behavior that was presented as mean and extreme patterns. Homogeneity was founded in the tide behavior at the area of interest, catalogued as microtidal, having also a range between the maximum and minimum values of the same magnitude as the range of the no tidal residual, which also presented higher values toward the Greater Antilles than on the south-western Caribbean, due to the more frequent transit of tropical storms and hurricanes. Differences of the order of centimetres were founded on the heights of the mean and extreme patterns of sea level at the three locations studied.Downloads
