Analysis of Horizontal Shear Data.

Abstract

The purpose of this study was to assess the value of drifter data taken by NRL for determining horizontal shears in the ocean. The first issue is an evaluation of shears from the smoothed data supplied by NRL along with an assessment of the significance of these evaluations. The other issue is a general assessment of the use of drifters for inferring horizontal shears. It appeared that three tasks were required to resolve these issues. These were: (Task 1) Perform an analysis on drogues 1, 3, 5, 9, 16 and 20 to obtain the differential kinematic properties (shear deformation, normal deformation, vorticity, and horizontal divergence) in a geographic coordinate system (i.e. north and east components); (Task 2) Perform the analysis as stated in Task 1 but with a coordinate system moving with the center of mass of the clusters. Both the large and small scale clusters were analyzed. The results are presented in tables and accompanied by graphs of the functions versus time; and (Task 3) Make a qualitative assessment of the calculation and the effect of turbulent processes.
