Short-Period Variations in a Great Lakes Coastal Current by Aerial Photogrammetry
Short-Period Variations Short-Period Variations
2009/3/24
Measurements of the surface velocity structure off the Keweenaw Peninsula of Lake Superior were obtained in 1971 and 1972, using aerial photography to track surface drift cards. Variations in the curr...
A theory of barotropic, nondivergent, zonally propagating waves on an equatorial beta-plant with topography is presented. The bottom contours are assumed to be parallel to the equator, so that the dep...
On Wind-Driven Current and Temperature Profiles with Diurnal Period in the Oceanic Planetary Boundary Layer
Wind-Driven Current Diurnal Period Temperature Profiles
2009/2/13
This paper describes a physically reliable model of the ocean surface layer. A Richardson-number-dependent stability function obtained from atmospheric boundary-layer data is applied to the oceanic la...
Normal Modes of the World Ocean. Part II：Description of Modes in the Period Range 8 to 80 Hours
World Ocean Period Range 8 80 Hours
2009/2/9
We have calculated normal modes with period between 8 and 80 h for a domain consisting of the Arctic, Atlantic, Indian and Pacific oceans. In this period range the numerical model has 56 modes, of whi...
A Statistical Study of Large-Scale, Long-Period Variability in North Pacific Sea Surface Temperature Anomalies
sea surface temperature Large-Scale Long-Period Variability
2009/2/7
Frequency domain principal components analysis, a technique which involves extracting the eigenvalues and eigenvectors of the cross spectrum of a multivariate time series, is used to analyze the devel...
The Generation of Diurnal Period Shelf Waves by Tidal Currents
Diurnal Period Shelf Waves Tidal Currents
2009/2/7
Continental shelf waves of diurnal period are shown to be generated by tidally induced Reynolds stresses within a bottom Stokes-scale boundary layer. The theory is applicable to a uniformly rotating, ...
Equatorial Currents at Semi-Annual Period in the Indian Ocean
Equatorial Currents Indian Ocean Semi-Annual Period
2009/2/7
Moored records of zonal velocity in the western equatorial Indian Ocean are dominated by motion of semi-annual period. The motion is coherent over an array spanning more than 1000 km along the equator...
Diurnal-Period Continental Shelf Waves along Vancouver Island：A Comparison of Observations with Theoretical Models
Diurnal-Period Theoretical Models Continental Shelf Waves
2009/1/21
Current and sea level data from the Coastal Oceanic Dynamics Experiment conducted of Vancouver Island from May 1979 to September 1980 reveal shelf waves of diurnal period whose motions dominate the fl...
High-Height Long-Period Ocean Waves Generated by a Severe Storm in the Northeast Pacific Ocean during February 1983
Long-Period Ocean Waves Northeast Pacific Ocean February
2009/1/20
Unusally severe storms occurred in the northeast Pacific Ocean between January and March 1983, and waves from these storms caused extensive erosion and damage along the U.S. west coast. Wave condition...
An Objective Analysis of the POLYMODE Local Dynamics Experiment. Part II：Streamfunction and Potential Vorticity Fields during the Intensive Period
Local Dynamics Experiment Streamfunction Potential Vorticity Fields Intensive Period
2009/1/10
An analysis is made of the geostrophic streamfunction, potential vorticity and dynamical balances for the mesoscale flow during the intensive Period of the POLYMODE Local Dynamics Experiment The metho...
Generation of Annual-Period Rossby Waves in the South Atlantic Ocean by the Wind Stress Curl
Annual-Period Rossby Waves South Atlantic Ocean Wind Stress Curl
2009/1/9
The properties of first-mode annual-period baroclinic Rossby waves generated by the observed wind stress curl in a numerical model of the South Atlantic and Southwest Indian oceans are presented. The ...
Observations of 20-Day Period Meridional Current Oscillations in the Upper Ocean along the Pacific Equator
Meridional Current Upper Ocean Pacific Equator
2009/1/6
Prominent oscillations of the meridional current, with a mean period of approximately 20 days, have been observed in the upper ocean over several years from May 1979 to October 1985 using moored curre...
Variability of Structure and Transport of the Florida Current in the Period Range of Days to Seasonal
Florida Current Period Range Seasonal
2009/1/6
Current measurements with five repeated moored arrays were carried out from April 1982 to June 1984 across the Florida Current between West Palm Beach and Grand Bahama Island; a reduced sixth array wa...
Long Period Swell Wave Events on the Norwegian Shelf
Long Period Swell Wave Norwegian Shelf continental shelf
2009/1/5
Wave records obtained by Waverider and heave/pitch/roll data buoys on the Norwegian continental shelf have been analysed in order to gain information on spectral characteristics (bandwidth, peak frequ...
