    Riemenschneider, Ulrike; Sheremet, Vitalii A. (Cambridge University Press, 2006-09-15)
    Motivated by work on tilted convection (Sheremet, J. Fluid Mech., vol. 506, 2004, p. 217), a set of experiments is presented here using the same set-up of a tilted tank attached to a rotating centrifuge with a 2.5 m arm. ...
  • The baroclinic adjustment of time-dependent shear flows 

    Poulin, Francis J.; Flierl, Glenn R.; Pedlosky, Joseph (American Meteorological Society, 2010-08)

    Pedlosky, Joseph (American Meteorological Society, 2010-05)
    A quasigeostrophic, two-layer model is used to study the baroclinic circulation around a thin, meridionally elongated island. The flow is driven by either buoyancy forcing or wind stress, each of whose structure would ...
  • Baroclinic instability of a meridionally varying basic state

    Pedlosky, Joseph; Thomson, James M. (Cambridge University Press, 2003-08-19)
    The baroclinic instability of a zonal current on the beta-plane is studied in the context of the two-layer model when the shear of the basic current is a periodic function of time. The basic shear is contained in a zonal ...
  • Baroclinic vortices over a sloping bottom 

    LaCasce, Joseph H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-09)
    Nonlinear quasigeostrophic flows in two layers over a topographic slope are considered. The evolution depends on the size of two parameters which indicate the degree of nonlinearity at depth. The first measures the ...
  • Barotropic Rossby waves radiating from tropical instability waves in the Pacific Ocean 

    Farrar, J. Thomas (American Meteorological Society, 2011-06)
    Tropical instability waves are triggered by instabilities of the equatorial current systems, and their sea level signal, with peak amplitude near 5°N, is one of the most prominent features of the dynamic topography of the ...
  • Barotropic tide in the northeast South China Sea

    Ostrom, William M.; Kemp, John N.; Krishfield, Richard A.; Proshutinsky, Andrey (Woods Hole Oceanographic Institution, 2004-01)
    The Beaufort Gyre Freshwater Experiment (BGFE) observational program was designed to measure the freshwater content of the upper ocean and sea ice in the Beaufort Gyre of the Arctic Ocean using bottom-tethered moorings, ...
  • Beaufort Gyre freshwater reservoir : state and variability from observations 

    Proshutinsky, Andrey; Krishfield, Richard A.; Timmermans, Mary-Louise; Toole, John M.; Carmack, Eddy C.; McLaughlin, Fiona A.; Williams, William J.; Zimmermann, Sarah; Itoh, Motoyo; Shimada, Koji (American Geophysical Union, 2009-06-24)
    We investigate basin-scale mechanisms regulating anomalies in freshwater content (FWC) in the Beaufort Gyre (BG) of the Arctic Ocean using historical observations and data collected in 2003–2007. Specifically, the mean ...
  • Bermuda’s tale of two time series : Hydrostation S and BATS 

    Phillips, Helen E.; Joyce, Terrence M. (American Meteorological Society, 2007-03)
    This paper describes the oceanic variability at Bermuda between 1989 and 1999, recorded in two overlapping hydrographic time series. Station S and Bermuda Atlantic Time Series Study (BATS), which are 60 km apart, both show ...
