| Zusammenfassung |
| This paper presents a stochastic weather generator based on analogues of
circulation (AnaWEGE). Analogues of circulation have been a promising
paradigm to analyse climate variability and its extremes. The weather
generator uses precomputed analogues of sea-level pressure over the North
Atlantic. The stochastic rules of the generator constrain the continuity in
time of the simulations. The generator then simulates spatially coherent time
series of a climate variable, drawn from meteorological observations. The
weather generator is tested for European temperatures, and for winter and
summer seasons. The biases in temperature quantiles and autocorrelation are
rather small compared to observed variability. The ability of simulating
extremely hot summers and cold winters is also assessed. |
