Time Evolution of Initial Errors in Lorenz's 05 Chaotic Model
Original language description
Initial errors inweather prediction grow in time and, as they become larger, their growth slows down and then stops at an asymptotic value. Time of reaching this saturation point represents the limit of predictability. This paper studies the asymptotic values and time limits in a chaotic atmospheric model for five initial errors, using ensemble prediction method (model's data) as well as error approximation by quadratic and logarithmic hypothesis and their modifications.We show that modified hypothesesapproximate the model's time limits better, but not without serious disadvantages.We demonstrate how hypotheses can be further improved to achieve better match of time limits with the model. We also show that quadratic hypothesis approximates the model'sasymptotic value best and that, after improvement, it also approximates the model's time limits better for almost all initial errors and time lengths.
