ABSTRACT

Somerville et al. 1976

Somerville, R.C.J., W.J. Quirk, J.E. Hansen, A.A. Lacis, and P.H. Stone, 1976: A search for short-term meteorological effects of solar variability in an atmospheric circulation model. J. Geophys. Res., 81, 1572-1576.

A set of numerical experiments is carried out to test the short-range sensitivity of the GISS (Goddard Institute for Space Studies) global atmospheric general circulation model to changes in solar constant and ozone amount. These experiments consist of forecasts initiated with actual atmospheric data. One set of forecasts is made with a standard version of the model, and another set uses the model modified by very different values of the solar constant (two thirds and three halves of the standard value) and of the ozone amount (zero and twice the standard amount). Twelve-day integrations with these very large variations show such small effects that the effects of realistic variations would almost certainly be insignificant meteorologically on this time scale.
