We consider a class of Bayesian dynamic models that involve switching among various regimes. As an example we produce a model for a runoff time Series exhibiting pulsatile behavior. This model is a mixture of three autoregressive models which accommodate 'rising,' 'falling,' and 'normal' states in the runoff process. The mechanism for switching among regimes is given by a three-state Markov chain whose transition probabilities are modeled on the basis both of past runoff values and of a time series of rainfall data. We adopt the Bayesian approach and use the Gibbs sampler in the numerical analyses. A study of a daily runoff series from Lake Taupo, New Zealand, is given.
