A two-scale approach for the turbulent mixing of momentum in an unstable
stratified boundary layer is proposed in an attempt to eliminate existing inconsistencies
between parameterized mixing of heat and momentum. The parameterization
of the large eddy stress is suitable for simple boundary layer models where computational
efficiency is important. We test the proposed formulation in a simple
boundary layer model and compare predicted momentum profiles with Lidar mean
momentum profiles from FIFE 1989. We examine the sensitivity of the proposed
mixing scheme to baroclinicity. While the proposed two-scale approach is able to
better predict observed conditions of well mixed momentum profiles, the complexity
of momentum transport in baroclinic conditions is not well approximated. / Graduation date: 1994
