A climate model is supposed to predict the probability for the formation of Bermuda highs, not use the Bermuda high as an empirical input.

A change in the ridge position of the Atlantic subtropical ridge (often referred to as the "Bermuda high," or "Azores high") has a direct impact on the tracks of tropical cyclones which typically form to its southern and western periphery.

For example, details about a “Bermuda high” today are essential empirical input data to let a weather model forecast what my Princeton weekend weather will be.
