Rainfall nowcasting by at site stochastic model P.R.A.I.S.E.

Abstract: Abstract. 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+1)Δt 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… Show more

“…In this period, correlation structure, mean and variance of the sample appear significantly homogeneous (Sirangelo et al, 2007). So the d/p ratio is equal to about 2050 and about 150 considering only rainy intervals.…”

“…the parameter ν, has been determined for every raingauge starting from sample partial autocorrelogram, and using the technique cited at point 2.1 (Sirangelo et al, 2007). The value of χ r,cr has been fixed equal to 0.025, and the estimate of ν has beenν=8, as depicted in Fig.…”
