High-Frequency and Low-Frequency Variability in Stochastic Daily Weather Generator and Its Effect on Agricultural and Hydrologic Modelling
Original language description
The high frequency and low frequency variabilities, which are often misreproduced by the daily weather generators, have a significant effect on modelling weather dependent processes. Three modifications are suggested to improve the reproduction of the both variabilities in a four variate daily weather generator Met&Roll: (i) inclusion of the annual cycle of lag0 and lag1 correlations among solar radiation, maximum temperature and minimum temperature, (ii) use of the 3rd order Markov chain to model precipitation occurrence, (iii) applying the monthly generator (based on a first order autoregressive model) to fit the low frequency variability. The tests are made to examine the effects of the three new features on (i) a stochastic structure of the synthetic series, and on (ii) outputs from CERES-Wheat crop model (crop yields) and SAC-SMA rainfall-runoff model (monthly streamflow characteristics, distribution of 5 day streamflow) fed by the synthetic weather series.
