8. Conclusions

The, climatological data sets used in this study and also those reported elsewhere by Mary Selvam and her group (see references in this paper References ) show that in a majority of cases interannual variability in atmospheric flows can be represented by the model predicted universal spectrum. Model concepts, if correct, rule out unambiguously, linear trends in climate. Climate change will only be manifested as increase or decrease in the natural variability. However, more stringent tests of model concepts and predictions are required before applications to such an important issue as climate change.
