"CIR 4507." Includes bibliographical references (page 5). "A first order Markov chain probability model is shown to conform closely to the long term average distribution of wet and dry spells at Winnipeg during the months of April to October, inclusive. Consequently, other parameters, such as" (a) probability of changeable weather, from wet to dry, and vice-versa, (b) number of wet days per month, and (c) average lengths of wet and dry spells, were calculated using the model. These values are shown to be in fair agreement with actual average values over the long term period. However, short term deviations from the model may be large"--Abstract.
