Tidal prediction, and the variation of the observed tide from the predicted tide at Newport, Oregon

Swanson, R. Lawrence (Robert Lawrence), 1938- 11 March 1965 (has links)
A tidal and sea level survey was begun in Yaquina Bay, Oregon, on 8 May, 1964. A continuous recording tide gage was installed at the pier of the Oregon State University Marine Science Center. An harmonic analysis of the observed data was made, and the major tidal constants were compared with those published by the Coast and Geodetic Survey. A program was written for the IBM 1410 computer, so that the tide could be predicted at any time using the tidal constants for the Newport area. An investigation of the "meteorological tide" was made by comparison of the predicted and observed tides. River stage, sea level variation, barometric pressure, and wind were considered. Lastly, a comparison was made between the predicted tide at Newport and the predicted maxima and minima of the tide at Newport as determined using the Coast and Geodetic Survey's tide table. / Graduation date: 1965

Forcing of the Quarterdiurnal Tide

Geißler, Christoph, Jacobi, Ch. 26 September 2018 (has links)
Ensemble calculations for the period from 2000 to 2010 were carried out with the middle and upper atmosphere model (MUAM), and an analysis of the quarterdiurnal tide is performed. The global temporal and latitudinal distributions of the quarterdiurnal tide are modeled with MUAM, and their forcing mechanisms are examined. The quarterdiurnal tides show a similar distribution over the year in the northern and southern hemisphere, with maxima of the amplitude in late winter and spring as well as in autumn. In the latitude-height distribution is also shown that the largest amplitudes of the quarterdiurnal tide are seen at midlatitudes. Due to the decreasing density with height, there is a general increase of the tidal amplitudes with height. The results of the forcing analyses show that direct solar forcing is most important, but also that non-linear forcing and gravity wave interaction with other tides have a non-negligible influence on the quarterdiurnal tide in the middle and upper atmosphere. / Mit dem Modell für die mittlere und obere Atmosphäre MUAM wurden Ensemble-Berechnungen für den Zeitraum 2000 bis 2010 durchgeführt und die vierteltägigen Gezeiten analysiert. Es wird auf die globale zeitliche und räumliche Verteilung der vierteltägigen Gezeiten eingegangen und deren Anregungsmechanismen untersucht. Die vierteltägigen Gezeiten zeigen einen ähnlichen Verlauf über das Jahr auf der Nord- und Südhalbkugel mit Maxima der Amplitude im späten Winter und Frühjahr sowie im Herbst. Ein ähnliches Bild zeigt sich auch für die Verteilung im Breiten-Höhen-Schnitt, wo die größten Amplituden der vierteltätigen Gezeiten in den mittleren Breiten zu finden sind. Aufgrund der abnehmenden Dichte mit der Höhe ist eine allgemeine Zunahme der Amplituden mit der Höhe zu beobachten. Es zeigte sich, dass der direkte solare Antrieb am stärksten ausgeprägt ist, aber auch, dass der nichtlinearer Antrieb und die Interaktion von Schwerewellen mit anderen Gezeiten einen nicht zu vernachlässigenden Einfluss auf die vierteltägigen Gezeiten in der mittleren und oberen Atmosphäre haben.
