V članku so predstavljeni temelji modeliranja meteoroloških polj v mezometeorološki skali (velikost pojavov od 10 do 100 km) in način modeliranja z večkratnim gnezdenjem, kakršen se uporablja v sistemu ARPEGE, ALADIN-LACE, ALADIN-SI. Opisane so nekatere lastnosti modela ALADIN in značilnosti modelskega prostora. Za primer intenzivnih padavin v zahodni Sloveniji (6.11.1997) so prikazani podatki meritev s klimatoloških postaj in rezultati modelskih izračunov akumulacije padavin. Analizirali smo možnost uporabe rezultatov izračuna padavin z modelom ALADIN-SI za napoved odtoka s pomočjo modela HEC-1.

Abstract
A mesometeorological modelling in a regional scale (the dimensions of the phenomena studied are from 10 to 100 km) with multiple nesting within the ARPEGE ALADIN models framework is introduced. Some characteristics of the ALADIN -SI model are described, and, for a selected case of intense precipitation, the operational outputs of the mesoscale meteorological ALADIN-SI model precipitation accumulation are evaluated with the use of operationally available data from the rain-gauge network. The mesoscale features of synoptic situations associated with the intense precipitation events are discussed. The possibility of using forecasted precipitation for predicting surface run-off with a hydrological model is discussed.
