Abstract:
We would like to examine the atmospheric stationary wave responses to greenhouse warming using the IPCC AR4 experiments, particularly those with multiple ensemble members. Past results with the CMIP2 experiments show that there are large variations among the different models in their stationary wave responses. Given the marginal statistical significance of these responses, it is necessary to have multiple ensembles to get robust stationary wave responses. IPCC AR4 experiments provide an ideal dataset for this purpose. Once a statistically robust stationary wave responses are established, they will be compared to different models’responses and the maintenance mechanisms will be examined using simple stationary wave models.
