Mj. Airey et al., EVALUATION OF SIMULATIONS OF TERRESTRIAL PRECIPITATION IN UK MET OFFICE HADLEY CENTER CLIMATE-CHANGE EXPERIMENTS/, Geophysical research letters, 23(13), 1996, pp. 1657-1660
This paper evaluates the simulation of precipitation in four successiv
e versions of the UK Met. Office/Hadley Centre global climate model (G
CM) that have: been used to perform climate change experiments. The pr
ecipitation fields over land from the control integrations of these fo
ur experiments are compared with observed precipitation on a global sc
ale and for selected regions. Globally, improvements in simulating mea
n monthly precipitation patterns occur with successive simulations. Th
e poorest correlations and highest root mean square errors occur in th
e boreal summer months. A major improvement in the simulation of the S
outh Asian summer monsoon by the most recent versions of the model is
noted. The pattern of temporal variability in the later versions over
global land areas is generally well simulated. The observed pattern of
temporal correlation between the Southern Oscillation Index and preci
pitation anomalies has improved in the latest model version.
