Global Ocean Tides. Part IV. The Diurnal Luni-Solar Declination Tide (K1), Atlas of Tidal Charts and Maps

摘要

In Part I of this report (A060 913), a unique hydrodynamical interpolation technique was introduced, extensively tested, and evaluated in order to partial global ocean tides in great detail and with a high degree of accuracy. This novel method has been applied to construct the diurnal luni-solar declination (K1) ocean tide with a relative accuracy of better than 5 cm anywhere in the open oceans. The resulting tidal amplitudes and phases are tabulated on a 1 deg x 1 deg grid system in an atlas of 42 deg x 71 deg overlapping charts covering the whole oceanic globe. A corresponding atlas of global corange and cotidal maps is included to provide the reader with a quick general overview of the major tidal phenomena. The specifying hydrodynamical parameters of the model are listed along with quoted sources of empirical tide data, and significant tidal features are explained and discussed. The diurnal K1 ocean tide is found to resemble qualitatively the semidiurnal M2 and S2 tides presented in Parts II (AD-A084 694) and III (AD-A104 333) of this report. However, major shifts of the positions of the amphidromes are apparent.
