This paper presents the results of numerical modelling of extreme precipitation on the southern coast of the Caspian sea using the WRF-ARW model with realistic and idealised conditions aimed at evaluating the orographic and lake effects. Verified against the observational data, this model reproduces the spatial distribution and the total amount of precipitation in selected episodes reasonably well, with a certain set of physical parametrizations. Sensitivity tests showed that the lake effect is evident only in the presence of orography. The total contribution of the warm Caspian sea and orography to the amount of precipitation is, on average, 50%.
