Evolution of daily temperature due to global change

Abstract

We consider the problem of estimating non-stationary temperature normals (the mean), at a daily timescale, which take into account deformations due to the global change of the annual cycle. In a second step, we consider not only the mean, but the whole distribution. Thus, we will present our methodological choices in a quantile regression framework to acquire the evolution of centiles throughout the 21st century. Although this technique provides a very convenient and powerful tool for studying changes in the distribution of a climate variable, this point of view raises issues that need to be addressed, such as quantile crossing.
