Abstract : An analysis of jet stream structure and energetics is performed using an objective scheme that calculates wind components normal and parallel to the jet axis, with provisions to explicitly calculate the eddy components of variables. Most of the meteorological data used is generated by a diagnostic-balanced, omega-equation model. Results indicate that above 500 mb observed winds and temperatures should be used versus computer generated data. There is some indication that between the jet entrance and exit regions the mean transverse vertical circulation reverses from thermally direct to thermally indirect. Kinetic energy is imported from below the jet into the jet stream region primarily by the mean pressure interaction at 500 mb. Thermal balance calculations indicate that the mean horizontal temperature advection and vertical transverse motion are primarily responsible for maintenance of the temperature structure about a jet.
