| Zusammenfassung |
| The purpose of this paper is to provide a method for perturbing Weather
Generators (WGs) for future decades and to assess its effectiveness. Here
the procedure is applied to the WG implemented within the UKCP09 package and
assessed using data from a Regional Climate Model (RCM) simulation which
provides a significant "climate change" between a control run period and a
distant future. The WG is normally calibrated on observed data. For this
study, data from an RCM control period (1961–1990) was used, then perturbed
using the procedure. Because only monthly differences between the RCM
control and scenario periods are used to perturb the WG, the direct daily
RCM scenario may be considered as unseen data to assess how well the
perturbation procedure reproduces the direct RCM simulations for the future. |
