Abstract : The range at which good forecasts of the weather are possible is limited by the rate at which separate solutions of the governing dynamic equations diverge from one another. Studies aimed at determining this rate have thus far employed a dynamical approach, an empirical approach, or a dynamical-empirical approach. A comparison of these three approach points to a value of about three days as the best estimate of the average doubling time for small differences between solutions. (Author)
