Seasonal variation of the M 2 tide | Ocean Dynamics - Springer
2014年1月9日 · The barotropic seasonal tidal variability is dominant in coastal and polar regions with relative changes of the tidal amplitude of 5–10 %. A comparison with the observations shows that the ocean circulation and tide model captures the seasonal pattern of …
The amplitude and phase of the M2 tidal constituent at LGM, as...
At LGM, the amplitude of M2 is much higher than in the modern ocean, as seen in panel (a) of Figure 4. Of particular note is the amplitude increase in the North Atlantic, between Greenland...
A likely role for stratification in long-term changes of the global ...
2024年5月17日 · Amplitude trends are predominantly negative, implying enhanced energy transfer to internal tides since the 1990s. Effects of stratification are also a relevant forcing of contemporary M 2...
Direct measurements of World Ocean tidal currents with surface …
2015年9月21日 · Tidal current characteristics (amplitude of semimajor axis, rotary coefficient, tidal ellipse inclination, and Greenwich phase) are mapped over the World Ocean from direct observations. The M2 currents dominate on all the shallow continental shelves with magnitude exceeding 60 cm/s.

2016年6月1日 · Two-dimensional plane wave fit. b. Parameters in the global mapping. a. Generation sources. b. Internal tidal beams. d. Interference pattern. Alford, M. H., 2003: Redistribution of energy available for ocean mixing by long-range propagation of internal waves. Nature, 423, 159–162, doi: 10.1038/nature01628.
Global tide simulations with ICON-O: testing the model ... - Springer
2020年12月8日 · The global tide is simulated with the global ocean general circulation model ICON-O using a newly developed tidal module, which computes the full tidal potential. The simulated coastal M2 amplitudes, derived by a discrete Fourier transformation of the output sea level time series, are compared with the according values derived from satellite ...
Global M2 internal tide and its seasonal variability from high ...
2012年10月10日 · The RMS amplitude for each 1° × 1° square in regions of the deep ocean (deeper than 1000 meter) has been computed, and shown inFigure 1. The results from satellite altimeter and model simulation show the same regional hot spots of internal tide generation, where local surface amplitudes of internal waves exceed 20 mm.
Seasonal amplitude of principal tidal constituents in shallow shelf ...
2024年10月15日 · Long-term trend of amplified seasonal amplitude caused by enhanced stratification is predicted. Understanding the seasonal variation (annual cycle) of tides is crucial for coastal management and the planning of coastal infrastructure, as well as pivotal for navigation safety, prediction of extreme sea levels and so on.
Ocean tides and resonance | Ocean Dynamics - Springer
2010年9月4日 · The LGM run shows a significant increase in the M2 tidal amplitude in several areas compared to the present-day control (Figs. 2a, 3a and 6a). The North Atlantic—especially Hudson Bay and the European shelf, the Weddell Sea, and parts of the Caribbean—experienced increases of over 1 m.
DGFI-TUM - Empirical ocean tide modeling
The amplitude (in cm) of the M2 ocean tidal constituent derived from the EOT20 tide model for the global ocean. The long time series of precise and nearly global altimeter measurements from missions with different sampling characteristics allow a comprehensive and very accurate empirical modeling of ocean tides.
