| Zusammenfassung |
| A single-site Neyman-Scott Poisson cluster model of
rainfall, with convective and stratiform cells, is fitted to data for 112
sites scattered throughout the UK using harmonic variables to account for
seasonality. The model is regionalised by regressing the estimates of the
harmonic variables on site dependent variables (e.g. altitude) to enable
rainfall to be simulated at any ungauged site in the UK. An assessment
of the residual errors indicates that the regression models can be used
with reasonable confidence for urban sites. Furthermore, the regional variations
of the model parameter estimates are found to be in agreement with meteorological
knowledge and observation. Simulated I h extreme rainfalls are found to
compare favourably with observed historical values, although some lack-of-fit
is evident for higher aggregation levels. |
