A diagnostic analysis was undertaken to determine whether vertically propagating waves in the lower atmosphere (tropospheric and stratospheric) were associated with solar forcings. The vertically propagating waves were identified by the wave energy changes in the vertical from 925 mb to 10 mb. The vertically propagating waves were compared with solar forcings and atmospheric stability changes. The analysis results were summarized for the solar maximum and minimum years (based on sunspot records) 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.
