| Zusammenfassung |
| The paper introduces a stochastic model to forecast rainfall heights at
site: the P.R.A.I.S.E. model (Prediction of Rainfall Amount Inside Storm
Events). PRAISE is based on the assumption that the rainfall height Hi+1
accumulated on an interval Δt between the instants iΔt and
(i+1Δt is correlated with a variable Zi(ν),
representing antecedent precipitation. The mathematical
background is given by a joined probability density fHi+1, Zi(ν)(hi+1 ,zi(ν)) in which
the variables have a mixed nature, that is a finite probability in
correspondence to the null value and infinitesimal probabilities in
correspondence to the positive values. As study area, the Calabria region,
in Southern Italy, was selected, to test performances of the PRAISE model. |
