Winter 1976 Data Systems Test wind data was used to produce a number of global kinematic fields. An interpolation scheme was developed to move the wind data from sigma levels to constant pressure levels. Time-averaged fields of the zonal wind component, meridional wind component, divergence, vorticity, steady energy and transient energy were computed for 200 mb, 500 mb and 850 mb. In addition, the standing kinetic energy and transient kinetic energy were decomposed by wavenumbers into energy spectra 200 mb and 500 mb for different latitudes. Results of this research were compared with other similar studies and showed favorable correlation. Resolution of synoptic scale features was good. Organized areas were found in the time-averaged divergence fields indicating that divergence features can be resolved in this data.
