Linear seas
Nettet[1] Linear trend analysis is commonly applied to quantify sea level change, often over short periods because of limited data availability. However, the linear trend computed over short periods is complicated by large-scale climate variability which can affect regional sea level on interannual to inter-decadal time scales. Nettetthe linear sea as explained further on. It is to be noted that using prescribed standard values, = 0 .07 and 0 .09 leads to optimal parameters with decay rate of power 5, but a much

Nettet8. des. 2015 · In previous work, researchers have started with a wave-group which matches the average shape of an extreme wave in a linear sea—the so-called NewWave. This was run backwards in time for a given number of periods under linear evolution before being run forwards using a nonlinear model (or in a physical wave-tank). Nettet6. jun. 2011 · Chao, Y. H. Yu, and Y. S. Li (Science, 320:212-214) have shown that sea level rise for the last eighty years has been linear, with a slope of 2.46 millimeters per year. Theirs is the sea level that has been corrected for the effect of water held in storage by all dams built since the year 1900.
