An analysis of solar driven circulation changes in the earth’s upper troposphere and lower stratosphere using the integrated global reanalysis data
The Global Reanalysis Data Set with integrated worldwide observations will be the basis for a global circulation solar impact analysis The solar ultraviolet flux varies with the key periodicities: the 11-year solar cycle and the 28-day average rotation rate of the sun. This investigation reviews the possible connection with a proposed solar-terrestrial coupling mechanism through the change in solar UV flux over these two repetitive periods. The 200 mb surface was chosen as region for investigation since the circulation changes are driven by changes in the static stability via heating through ozone absorption. A discussion of the temperature and gradient variations at solar minima versus solar maxima and with the 28-day solar rotation is presented to demonstrate possible climate variations due to changing solar UV flux levels.
