  • Nonlinear adjustment of a localized layer of buoyant, uniform potential vorticity fluid against a vertical wall 

    Helfrich, Karl R. (2006-01-29)
    The nonlinear evolution of a localized layer of buoyant, uniform potential vorticity fluid of uniform depth H, width w0 and length L released adjacent to a wall in a rotating system is studied using reduced-gravity ...
  • Nonlinear disintegration of the internal tide 

    Helfrich, Karl R.; Grimshaw, Roger H. J. (American Meteorological Society, 2008-03)
    The disintegration of a first-mode internal tide into shorter solitary-like waves is considered. Since observations frequently show both tides and waves with amplitudes beyond the restrictions of weakly nonlinear theory, ...
  • The nonlinear downstream development of baroclinic instability 

    Pedlosky, Joseph (Sears Foundation for Marine Research, 2011-07-01)
    The downstream development in both space and time of baroclinic instability is studied in a nonlinear channel model on the f-plane. The model allows the development of the instability to be expressed on space and time ...

    Flierl, Glenn R.; Pedlosky, Joseph (American Meteorological Society, 2007-04)
    The nonlinear dynamics of baroclinically unstable waves in a time-dependent zonal shear flow is considered in the framework of the two-layer Phillips model on the beta plane. In most cases considered in this study the ...
  • Nonlinear generation and loss of infragravity wave energy 

    Henderson, Stephen M.; Guza, R. T.; Elgar, Steve; Herbers, T. H. C.; Bowen, A. J. (American Geophysical Union, 2006-12-08)
    Nonlinear energy transfers with sea and swell (frequencies 0.05–0.40 Hz) were responsible for much of the generation and loss of infragravity wave energy (frequencies 0.005–0.050 Hz) observed under moderate- and low-energy ...
  • Nonlinear interactions among standing surface and internal gravity waves 

    Joyce, Terrence M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1972-06)
    A laboratory study has been undertaken to measure the momentum transfer from surface to internal gravity waves in a nonlinear, resonant interaction. The interacting waves form triads for which σ1s - σ2s ± σI = 0 and κ1s - ...
  • Nonlinear internal waves over New Jersey's continental shelf 

    Shroyer, Emily L.; Moum, James N.; Nash, Jonathan D. (American Geophysical Union, 2011-03-23)
    Ship and mooring data collected off the coast of New Jersey are used to describe the nonlinear internal wave (NLIW) field and the background oceanographic conditions that formed the waveguide on the shelf. The subinertial, ...
  • Nonlinear stratified spindown over a slope 

    Benthuysen, Jessica A.; Thomas, Leif N. (Cambridge University Press, 2013-06-05)
    Nonlinear stratified spindown of an along-isobath current over an insulated slope is shown to develop asymmetries in the vertical circulation and vertical relative vorticity field. During spindown, cyclonic vorticity is ...
  • Nonlocal transport due to Langmuir circulation in a coastal ocean 

    Kukulka, Tobias; Plueddemann, Albert J.; Sullivan, Peter P. (American Geophysical Union, 2012-12-11)
    We present observations and simulations of large-scale velocity structures associated with turbulent boundary layer dynamics of a coastal ocean. Special purpose acoustic Doppler current profiler measurements revealed that ...
  • A nonparametric test for change in variability using a proxy record with an application to ENSO 

    Solow, Andrew R.; Beet, Andrew R. (American Geophysical Union, 2008-10-09)
    A common problem in climate science is determining whether the pattern of variability in a particular process or variable has changed over time. When the modern observational record is short, this problem can be addressed ...
  • Nonvolcanic seafloor spreading and corner-flow rotation accommodated by extensional faulting at 15°N on the Mid-Atlantic Ridge : a structural synthesis of ODP Leg 209 

    Schroeder, Timothy; Cheadle, Michael J.; Dick, Henry J. B.; Faul, Ulrich; Casey, John F.; Kelemen, Peter B. (American Geophysical Union, 2007-06-28)
    Drilling during ODP Leg 209, dredging, and submersible dives have delineated an anomalous stretch of the Mid-Atlantic Ridge north and south of the 15°20′N Fracture Zone. The seafloor here consists dominantly of mantle ...
  • Nonvolcanic tectonic islands in ancient and modern oceans 

    Palmiotto, Camilla; Corda, Laura; Ligi, Marco; Cipriani, Anna; Dick, Henry J. B.; Douville, Eric; Gasperini, Luca; Montagna, Paolo; Thil, Francois; Borsetti, Anna Maria; Balestra, Barbara; Bonatti, Enrico (John Wiley & Sons, 2013-10-24)
    Most oceanic islands are due to excess volcanism caused by thermal and/or compositional mantle melting anomalies. We call attention here to another class of oceanic islands, due not to volcanism but to vertical motions of ...
  • North American climate in CMIP5 experiments. Part II: evaluation of historical simulations of intraseasonal to decadal variability 

    Sheffield, Justin; Camargo, Suzana J.; Fu, Rong; Hu, Qi; Jiang, Xianan; Johnson, Nathaniel; Karnauskas, Kristopher B.; Kim, Seon Tae; Kinter, Jim; Kumar, Sanjiv; Langenbrunner, Baird; Maloney, Eric; Mariotti, Annarita; Meyerson, Joyce E.; Neelin, J. David; Nigam, Sumant; Pan, Zaitao; Ruiz-Barradas, Alfredo; Seager, Richard; Serra, Yolande L.; Sun, De-Zheng; Wang, Chunzai; Xie, Shang-Ping; Yu, Jin-Yi; Zhang, Tao; Zhao, Ming (American Meteorological Society, 2013-12-01)
    This is the second part of a three-part paper on North American climate in phase 5 of the Coupled Model Intercomparison Project (CMIP5) that evaluates the twentieth-century simulations of intraseasonal to multidecadal ...
  • North Atlantic climate variability in coupled models and data 

    Kravtsov, Sergey K.; Dewar, William K.; Ghil, M.; Berloff, Pavel S.; McWilliams, James C. (Copernicus Publications on behalf of the European Geosciences Union, 2008-01-18)
    We show that the observed zonally averaged jet in the Northern Hemisphere atmosphere exhibits two spatial patterns with broadband variability in the decadal and inter-decadal range; these patterns are consistent with an ...
