Sentences with phrase «nonlinear sea level trends»

Not exact matches

And Kate is right, that a 4 - or 5 - year trend is pretty meaningless anyway since sea level changes are decidedly nonlinear.

Different approaches have been used to compute the mean rate of 20th century global mean sea level (GMSL) rise from the available tide gauge data: computing average rates from only very long, nearly continuous records; using more numerous but shorter records and filters to separate nonlinear trends from decadal - scale quasi-periodic variability; neural network methods; computing regional sea level for specific basins then averaging; or projecting tide gauge records onto empirical orthogonal functions (EOFs) computed from modern altimetry or EOFs from ocean models.
