Frontal wave development over the Southern Ocean
Thesis (Ph. D.)--University of Washington, 2003. The development of frontal waves over the Southern Ocean is described using SeaWinds-on-QuikSCAT scatterometer surface winds. A planetary boundary layer model is used to construct surface pressure fields and correct the wind errors due to rain contami...
