Effects of Vertical Viscosity on Kelvin Waves
Publisher: American Meteorological Society
Abstract: An analytic theory is presented for free, barotropic Kelvin waves subject to constant, vertical eddy viscosity on a semi-infinite, f-plane shelf of constant depth bordering a straight, vertical coast. A coastal boundary ...
An Analytic Theory on How Friction Affects Free Internal Waves in the Equatorial Waveguide
Publisher: American Meteorological Society
Abstract: We study theoretically the effects of linear (Rayleigh) friction on free internal waves in the equatorial wayeguide. The waves may be vertically propagating or in standing vertical modes. Analytic solutions on a beta-plane ...
Barotropic Rossby Waves in a Zonal Current: Effects of Lateral Viscosity
Publisher: American Meteorological Society
Abstract: The behavior of a barotropic Rossby wave in a zonal current is studied theoretically using a beta-plane ocean of constant depth in which the current depends only on latitude. The wave may be reflected or absorbed, depending ...
Near-Inertial Internal Waves Observed on the Outer Shelf in the Middle Atlantic Bight in the Wake of Hurricane Belle
Publisher: American Meteorological Society
Abstract: On 10 August 1976 Hurricane Belle passed rapidly over the highly stratified shelf of the New York Bight. Records from Aanderaa current-meter moorings show that the response to the hurricane depended strongly on bathymetry. ...
Interpretation of North Pacific Variability as a Short- and Long-Memory Process
Publisher: American Meteorological Society
Abstract: A major difficulty in investigating the nature of interdecadal variability of climatic time series is their shortness. An approach to this problem is through comparison of models. In this paper a first-order autoregressive ...
Seasonal and Regional Variation of Pan-Arctic Surface Air Temperature over the Instrumental Record
Publisher: American Meteorological Society
Abstract: Instrumental surface air temperature (SAT) records beginning in the late 1800s from 59 Arctic stations north of 64°N show monthly mean anomalies of several degrees and large spatial teleconnectivity, yet there are systematic ...
The Harmonic Constant Datum Method: Options for Overcoming Datum Discontinuities at Mixed–Diurnal Tidal Transitions
Publisher: American Meteorological Society
Abstract: The harmonic constant datum (HCD) method is a computationally efficient way of estimating tidal datums relative to mean sea level, without the need to compute long time series. However, datum discontinuities can occur ...
Effects of Tides on Maximum Tsunami Wave Heights: Probability Distributions
Publisher: American Meteorological Society
Abstract: A theoretical study was carried out to understand how the probability distribution for maximum wave heights (?m) during tsunamis depends on the initial tsunami amplitude (A) and the tides. It was assumed that the total ...
Characterizing the European Sub-Arctic Winter Climate since 1500 Using Ice, Temperature, and Atmospheric Circulation Time Series
Publisher: American Meteorological Society
Abstract: This study describes winter climate during the last 500 yr for the greater Baltic Sea region through an examination of well-documented time series of ice cover, sea level pressure, and winter surface air temperatures. These ...
