A diagnostic analysis was undertaken to determine whether a theorized mechanism for lower atmospheric (tropospheric and stratospheric) wave energy shifts could be driven by solar forcings through changes in stability. The proposed mechanism assumes that when the atmospheric stability changes, the energy in the atmospheric long waves (Rossby waves) must shift to accommodate the modified state. The results were summarized for the wave energy analysis that compared solar maximum and minimum years for three solar forcing timescales: the 11-year solar sunspot cycle (decadal scale), the annual cycle (due to astronomical geometry changes causing variations in solar output as received at the Earth), and the 28-day solar rotational cycle (monthly). The analysis used the temperature fields in the National Center for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) Reanalysis Data. The solar radio flux (10.7 cm) was used as the proxy for solar short wave output since daily observed values were available daily for the entire 50 year plus record of the Reanalysis Data.
