DESCRIPTION:Please join us as we welcome Dr. Andrew Wilmot from the School 
 of Marine Science and Technology at Newcastle University for his seminar t
 itled 'Source-sink and wind stress curl driven planetary flows in a polar 
 basin'. Coffee will be served.\n\nAbstract\n\nAnalytical process models ar
 e developed to study linear\, steady-state\, source-sink and wind stress c
 url driven barotropic planetary flows in a circular polar basin on the sph
 ere with two open boundaries and simple shelf topography. The leading orde
 r dynamical balance is geostrophic except near the boundary of the basin a
 nd the shelf edge\, where dissipation in the form of either linear bottom 
 friction or eddy diffusion becomes significant. Full spherical geometry is
  retained in the derivation of the barotropic vorticity equation. Subseque
 ntly\, an overlooked approximation in the refereed literature of the sixti
 es is adopted whereby the latitudinal dependence in the coefficients of th
 e vorticity equation are suppressed\, hence allowing analytical solutions 
 to be obtained. The approximation is justified a posteriori and the study 
 compares the analytical solutions with numerical solutions obtained from t
 he NEMO Ocean modelling system configured for the same spherical cap domai
 n. The NEMO model is then used to investigate the impact of a shelf and si
 mple representation of the Lomonosov Ridge on the structure of both wind a
 nd source—sink driven flows\, where analytical solutions cannot be obtaine
 d. The study concludes with a discussion about how these experiments shed 
 light on the subtle interplay between the complex Arctic basin topography 
 and the wind and boundary driven sea ice-ocean circulation.\n
