Suppose we have a methereological model which describes the weather change as a Markov chain: we assume that the weather on each day depends only on the weather of the previous day. Suppose further that we extended this model so as to consider season change. defining a different transition table for each season. Would this violate the Markov property of the season change? I think it would not, since the weather would still depend just on the previous day, no matter if it was another season. Am I right?
