H. Van Loon et Dj. Shea, A probable signal of the 11-year solar cycle in the troposphere of the northern hemisphere, GEOPHYS R L, 26(18), 1999, pp. 2893-2896
The existence of a signal of the 11-year solar cycle in the geopotential he
ights of the lower half of the stratosphere implies, through hydrostatic ar
gument, an association with the temperatures in the troposphere. We have de
fined this association for the layer between 750hPa and 200hPa by means of
the NCEP/NCAR re-analyses for the period 1958-1997. In the zonal average it
is estimated to be 0.15 degrees C-0.2 degrees C for the whole of the North
ern Hemisphere in summer, and about the same for the tropics-subtropics in
March-December.
