- Lambert, F. H., N. P. Gillett, D. A. Stone, and C. Huntingford, 2005: Attribution studies of observed land precipitation changes with nine coupled models. Geophys. Res. Lett., 32, doi:10.1029/2005GL023654.
Global-land mean observations of 20th century
precipitation are compared to modelled values using an
optimal regression technique for nine general circulation
models. The combined influence of major anthropogenic
and natural forcings is detected in five cases. Comparing the
accuracy of precipitation and temperature simulation of
each model, we find that low temperature simulation
accuracy produces low precipitation simulation accuracy,
but temperature accuracy does not determine precipitation
accuracy in general. Model formulation appears to be more
important for accurate precipitation simulation than
inclusion of a more complete set of forcings. The
implications for possible constraints on land precipitation
are discussed.
