Synopsis

The motion of a density-stratified fluid in a rotating frame of reference; important parameters and their magnitudes; 'homogeneous flows' in the atmosphere and ocean; shallow-water and Rossby-wave motion; western boundary currents; gradient-wind balance and vortex motion; dynamics of stratified fluids, including stability, blocking, internal gravity waves and thermal-wind balance.

Objectives

Upon the completion of this unit, students will:

  1. understand the equations of fluid motion in an inertial reference frame, and be able to extend them to both a rotating frame of reference and a density-stratified fluid;
  2. appreciate how to approximate the full equations in circumstances which are relevant to motions in the atmosphere and/or oceans of various scales;
  3. recognise the constraints that rotation places on fluid motion and understand how this affects the motion of the atmosphere and ocean;
  4. understand the dynamics of wave motions, including Rossby waves, and be able to determine and interpret the group velocity of a dispersive wave disturbance;
  5. recognise the role of rotation in atmospheric vortices of different scales;
  6. appreciate the key effects introduced by density stratification, including stability, blocking and the dynamics of internal gravity waves;
  7. be able to interpret observational data and recognise evidence of the dynamics that were examined in the approximated theoretical analysis related to objectives 3-6 above;
  8. be able to communicate clearly the key concepts covered in the unit, both verbally and in written form.
